Graphic formats without loss of brightness. Graphic format. JPEG, GIF and PNG are the most widely used graphics formats

Most Popular graphic formats, іz yakim be able to stick to the Internet - JPEG, GIF and PNG. Let's talk about the peculiarities of their skin, lady short description that vkakamo sphere zastosuvannya. It is also possible to understand how you can quickly reformat the image for the help of other programs and navigate graphic editors, even if it is far from being skin-friendly, you can read new or small image formats.

What is a graphic format?

For the cob, let's say a few words about the understanding of the graphic format, in order to make it clearer, with which we can rightly. Given to the appointed persons, a way is assigned to save those different images and photographs. The leather graphic format has its own methods, especially in the area of ​​congestion. Fallow in the same image, which may be different, may be different in size, deep in color, especially in victoria.

Change raster, vector and complex formats. And in this article, we will only talk about raster graphics and ways of saving, more files can be expanded, as if showing the relevance of the image itself to it.

JPEG - old and new

Pochnemo, maybe, from the most popular that extended extension. So, JPEG (which is also designated for the help of another shorthand - JPG) is most commonly used on the Internet. Guess: Navigate your photos, expand on the camera or phone, expand.jpeg.

In this format, the method is widely distinguished, which is sometimes indicated on the quality of the picture. Vіn dosit popular, regardless of those that a license is needed for this vikoristannya. The depth of the color is 24 bits.

GIF - creations for creating animated images and more

Otzhe, rozіbravshi for you jpeg format, we are guilty of guessing and others for popularity - GIF. Vin - one of the oldest in the world of raster graphics. Vikoristovuetsya also for the exchange of images for the help of the Internet, especially - email. It is squeezed without wasting power, and the depth of the color becomes 8 bits. Encourage not only transparency, but also animation.

Here varto respect that when converting the effect of animation is used, it is obvious that the format of the file does not support it.

PNG is the latest analogue of GIF

We have chosen the JPEG and GIF formats for you, now let's talk about PNG. Yogo richly koristuvachіv the Internet is called a shortened version of GIF. The reason for this is that it is based on the very methods of saving that files with the .gif extension have. Immediately guess about those, on the vіdmіnu vіd svogo opednik, vіn not vіmagає licenzії, which is important.

When the information is compressed, the quality of the picture does not suffer, like the front format. With whom the head is the head of the one who allows the vicorist to make an uncircumscribed number of colors. Varto indicates that the depth of the color can reach 48 bits. Through the format, it is completely new, without yet taking away the popularity of the world, and even then you can spread it on the Internet.

How to convert babies? Program change extensions

So, we have chosen the JPEG, GIF and PNG formats - the largest extensions that can be shown on And now let's talk about those, how to change the format of that other image.

Some people have to deal with such a problem, if the browser, program, attachment does not support the file with other extensions, especially if it is old, but the format is clearly new. In such situations, there is a need for reformatting the image. How to solve the problem as quickly as possible?

In order to change the format, you can speed it up with the standard Paint program. For example, let's figure out how to translate the JPEG format, whether it's an image. For whom it is sufficient, I will need a photograph for help Paint programs otherwise, pressing on need an image right mouse button, select "Change". After seeing the picture, select in the "File" menu (for newer versions of the main program menu) the "Save Yak" item, and then select the format you need in the window, to this particular type- JPEG or JPG.

For these purposes, it is good to use CorrelDRAW, PhotoShop, as well as special photo converters: PicJet Converter, FastStone PhotoResizer and many others. Acts from them allow you to work batch processing an image that means that an hour of work from her will pass.

Podbag

You and I have sorted out what is a graphic format, have indicated on the basis of the main popular graphic formats, their application, have given a short description of the dermal format. It was also appreciated by those that the JPEG format is the most popular for the whole hour.

We have recognized, how to quickly change the image format for help standard programs on a computer or laptop. So they said a couple of words about those that are special converters, for the help of which you can quickly and easily change

Qia article є a short look three main graphic formats to get to the Internet. Flash (SWF) was not taken from rozrahunok, but for this review, a plugin is needed and the format is vector, not raster.

For accuracy, we will put a plate in which all three formats we have looked at are characterized.

Looking at the tables above, we can see the following:

GIF or PNG-8 is best suited for saving image details (when working in a color range, which is 256 colors) and for web graphics, which can erase text.

JPEG (or JPG) is best suited for photographers, small files have a small file size and a wide color range. . GIF is suitable for simple animation (we don’t talk about PNG in this mode, windows don’t support animation).

PNG-24, regardless of the size of the file, is an indestructible option, if you do not want to spend it like an image (you can see the details and add noise to the photo).

You can easily convert JPEGs with a low compression level, so you can show photos for cursive images without any problems. swedish internet", shards in any way, regardless of the size of the file, you take the image of good quality."

Otzhe, in summary. PNG-8 is suitable for simple images when published on the Internet. JPEG is suitable for photographs, PNG-24 is also useful for working with them, but in any case, you take a larger file size in JPG format. GIF is suitable for solving on the Internet.

Empirically

You can dwell on the topic for a long time, which of the formats is better, but it will be the most correct to marvel at, how the stench is practiced in practice - we’ll take care of it. Let's take three differences for a different image, and we'll check them out. So, the first sample of the image will be a photo of the cross.

To match the formats, the command File > Safe for Web was used in Photoshop CS2. How can we change the little one, first image, known as Original, maybe highest quality and the largest expansion (another pack, even if it’s a break :)). Here you can bypass PNG 24, but check that the JPG is original here, and it means that the compression ratio is the least - so you will select High for the Jpeg format in the settings of the Safe for Web dialog window, then the rozmir will be zovsіm іnshі, and іkіst іѕ nоt hіrе . Larger images to improve compression in different formats.

It is possible to extract images, which gives the best approximation to the original, the result is PNG-24, but the wine file is reduced by 50%, at that time how to finish the JPEG file high capacity(80) – more lower by 90%. Let's take a look at other similarities to the JPEG format.

The best option between the size and quality in this case would be JPEG with equal compression 60. I lost my "nearby" look at GIF and PNG-8.

Here we have an insignificant advantage in the end file and the quality of the picture in PNG-8 format before GIF. At the same time, JPEG formats are accepted, both for the quality and for the size of the file. In this way, when preparing an image for publication on the Internet for photographs, it will be rational to win JPEG with a quality of 60 - change the size of the file to a lower quality level, but you will not be satisfied with looking at such a picture.

Porada:

If you want to guess about other formats, I’ll say that if you want to save a file without defects in compression, then save it either in RAW, or in PSD, or in Tiff. And if you need to show the file to Merezh with minimal costs, but with the best value, then boldly choose JPEG with a quality of 100% - you won’t see any of the same visible defects.

JPEG, GIF, PNG and logos

Now, as far as we know, what kind of wicking format for photographs, we can see why for logotypes (their publications in Merezh) it’s better to vindicate PNG-8 :).
Let's get it from JPG. It is not important to remember the appearance of characteristic artifacts on both sides of the objects and the great number of other formats in the file expansion. For similar parameters of GIF and PNG, the rest allows you to take a smaller file size for saving optimal bitness. I think the additional comments are welcome here.

jpeg, gif, png ta tlo

Lost estimate, how to pour on types background images scho to be promoted by webmasters for their sites, other formats.

The difference between formats in this case is minimal, so I especially respect the need to add the size of the final file, and here, for obvious advantage, we change JPEG to quality 60.

Podbags

For painting images, so as not to avenge animation and transparency, best option Will win PNG-8, іnakshe - Gif. If an image is a photograph, or if you prefer photo elements, use JPEG. The variation of PNG-24 does not have any sense, so in which case you will not know the optimum between the quality and the size of the JPEG itself (name for quality 100).

When creating sites at the stage of layout, you need to specify the choice of the next format for saving the image. The image can be taken from any PNG, JPEG, GIF or dozens of other formats, or you can choose any format to transfer better quality with the minimum size of the image file?

What file format to choose?

GIF format surrounded by 256 colors. This format is without cost and with some variation, minimal image compression is achieved. The GIF format supports animation (the only one of all formats) that transparency, but save the picture in the dark. For the peculiarities of the algorithm, it is better to squeeze the image, in a way, vertical lines (for the web, for example, you can have vertical divisions of smog, single-color icons, graphic dots, too). Vіn can be used for choosing a chair, textual and symbolic graphics for a small file size.

PNG formatє format, in which the stisk is entered without cost. In this format, the leather pixel has 3 color channels (RGB - red, green, blue), and by this, a new color formation of the image is realized without confusion. For the brightness of color fermentation PNG format You can reverse the JPG, but after the expansion, the file will also be larger. The PNG format supports the difference in transparency (same transparency). For rahunok features, the algorithm of the wines is already kindly squeezed by the image, in which there are horizontal lines. If it is worth choosing to save the file in GIF or PNG format, for vipadkіv if the picture is a primitive line, then you should pay attention to the position of these lines - tobto. in the GIF format, choose to save the image with vertical lines, PNG - horizontal. png by hand selection for picking up a chair, text and iconic graphics in a small file.

JPG formatє format, de є spend color. The algorithm of work in this format is such that in a new way the images with gradients are squeezed together (the colors of the first pixel are taken in the gradient of the rest, and when the image is displayed, all the intermediate colors between the images are calculated), smaller rozmіrі, lower BMP format. Photos, transfusions, logos, backgrounds are better saved in JPG format.

In this manner, with the development of sites, you can reach even more good results at the shvidkost for the rahunok the right choice image capture format.

Fitting the material - press, be kind, on the button =)

We are all interested in the image, creating a photo, robimo "memi", to share them social measures. A rich image should be created without thinking about it, but which format of a graphic file is most suitable for a particular type. Tsya article does not stop fakhіvtsіv raster and vector graphics. We won’t cover the rest of this short analysis of graphic formats, in order to better understand for some purposes to win that other format. So let's do it.

Short analysis of graphic file formats

1. JPG/JPEG/JFIF
2. TIF/TIFF

Raster vs vector

Let's go down to five selected file formats first, good to know that there are two main graphic families: raster and vector, and all image file formats, repackaged below, go up to the raster family.

For raster graphics, images are selected from pixels, just like vector graphics are selected from highways, about business lines.

Shrinking files

In addition, image file formats can be differentiated based on compression effects, which are called compression. There is a large number of different squeezing schemes, but the essence of their reasoning can be known in one task - squeezing a raster file is more efficient. squeeze graphic file there is no sense, the shards of yoga rosemir can not be deposited in terms of scale, like in a large number of paths in a new one.

Compression can even more effectively squeeze the image literally twice and bigger. Ale, if it is possible, it will always be a loss of brightness, so the main compression algorithm is to see a few pixels and replace them with one or two similar ones for the image. The compression file will in no way be faithful to the original, for some reason. Let's talk about tsedali. Shrinking files sound suitable for small photographs and not suitable for prof. small illustrations, presentations.

Compression without loss is the same as the same output file, compression scales without compression are exactly the same as the original.

Image JPG/JPEG/JFIF

Abbreviation vіd: Joint Photographic Experts Group - Joint Photographic Experts Group.

File extension: .jpg / .jpeg

The widest media format bitmap files image. Digital cameras capture images on their own in the same format. JPEG files are blocked by the embossing method, which can significantly change the size of the file without any significant corruption.

Minusi: this format is not protected from the degradation of generations. Tse means that in case of skin redagulation, the preservation of the quality of the image with the skin new version the file will be corrupted.

Zastosovnіst: opaque images, attachments for capturing images (gadgets, cameras, action cameras).

PNG image format

Abbreviation vіd: Portable Network Graphics - portable network graphics

File extension: .png

This is a cost-free alternative to GIF with a valid external code, which means 16 million colors, for a GIF, a maximum of 256-color palette. Tse best format files for images from saving dzherel colors. The format is suitable for transferring the balance tone. Animation PNG file available in APNG format. Qi files, as a rule, may background.

Minusi: Most suitable for files of great expansions. The PNG format itself does not support animated graphics.

Zastosovnіst: editing images, web images, images with improved balls, such as transparency or the effect of fading.

TIF file extension

Abbreviation vіd: Tagged Image File Format - format for saving raster graphic images.

File extension: .tif / .tiff

Gnuchky file format, easy to expand, save files with a great depth of color. Qi files mayut clear the ashes. The stench is ideal for company logos.

Minusi: Not ideal for web browsers

Zastosovnіst: A first stage of photographic files with a friend. OCR software packages.

GIF file format

Abbreviation vіd: Graphics Interchange Format - image exchange format.

File extension:.gif

If you want GIF, you can have a low level of compression in the majority of video formats, which format is the most popular medium for animation images.

Minusi: 8-bit color palette format (256 colors) and not suitable for photographic images or smoothing.

Zastosovnіst: Graphics, for example, using decals of colors, for example, simplified by diagrams, logos and animations, for example, add up to more than 50% of one color.

BMP image file format

Abbreviation vіd: Bitmap Picture - literally a format for taking bitmap images

File extension:.bmp

Tsey format rozroblenno Microsoft and destinations for saving large compressed files in the middle of Windows.

Minusi: This format is not embossed.

Zastosovnіst: the structure of the format was simplified to make bmp files ideal for Windows.

The most wide-ranging image file formats, like vikoristovuyut koristuvachі in a given hour. Now, if you know which of them is ideal for any purpose, you can better understand the files of some graphic formats to win for yourself.
