Most common graphic file formats




















A vector EPS file is one of the most preferred formats by printers, promotional product companies, silk screeners, banner and sign companies, and other third party creatives. PDF files can be shared, viewed and printed by anyone with the free Adobe Reader software. Most commonly used by designer and printers. PSD files can only be opened using Photoshop and may be created in layers.

The level of compression in JPG files can vary in resolution with high quality for desktop printing, medium quality for web viewing and low quality for email. When compressed repeatedly the overall quality of a JPG image is reduced.

Almost all browsers can support the use of GIF files, which use a compression scheme to keep the file size small. See the Chromium bug , and Firefox bug for more information. The following sections provide a brief overview of each of the image file types supported by web browsers. In the tables below, the term bits per component refers to the number of bits used to represent each color component. For example, an RGB color depth of 8 indicates that each of the red, green, and blue components are represented by an 8-bit value.

Bit depth , on the other hand, is the total number of bits used to represent each pixel in memory. Conceptually similar to the animated GIF format which has been in use for decades, APNG is more capable in that it supports a variety of color depths , whereas animated GIF supports only 8-bit indexed color. APNG is ideal for basic animations that do not need to synchronize to other activities or to a sound track, such as progress indicators, activity throbbers , and other animated sequences.

They're also commonly used for the animated portions of web browsers' user interfaces. Note: AVIF has potential to become the "next big thing" for sharing images in web content. It offers state-of-the-art features and performance, without the encumbrance of complicated licensing and patent royalties that have hampered comparable alternatives. AV1 is a coding format that was originally designed for video transmission over the Internet. The format benefits from the signficant advances in video encoding in recent years, and may potentially benefit from the associated support for hardware rendering.

However it also has disadvantages for some cases, as video and image encoding have some different requirements. AVIF does not support progressive rendering, so files must be fully downloaded before they can be displayed. For larger file size the impact can become significant, and you should consider using a format that supports progressive rendering.

The BMP Bitmap image file type is most prevalent on Windows computers, and is generally used only for special cases in web apps and content. Warning: You should typically avoid using BMP files for web site content. The most common form of BMP file represents the data as an uncompressed raster image, resulting in large file sizes compared to png or jpg image types.

More efficient BMP formats exist but are not widely used, and rarely supported in web browsers. BMP theoretically supports a variety of internal data representations. The simplest, and most commonly used, form of BMP file is an uncompressed raster image, with each pixel occupying 3 bytes representing its red, green, and blue components, and each row padded with 0x00 bytes to a multiple of 4 bytes wide.

While other data representations are defined in the specification, they are not widely used and often completely unimplemented. These features include: support for different bit depths, indexed color, alpha channels, and different pixel orders by default, BMP is written from bottom-left corner toward the right and top, rather than from the top-left corner toward the right and bottom.

In , the CompuServe online service provider introduced the GIF Graphics Interchange Format image file format to provide a compressed graphics format that all members of their service would be able to use. Each pixel in a GIF is represented by a single 8-bit value serving as an index into a palette of bit colors 8 bits each of red, green, and blue.

The length of a color table is always a power of 2 that is, each palette has 2, 4, 8, 16, 32, 64, or entries. To simulate more than or colors, dithering is generally used.

It is technically possible to tile multiple image blocks, each with its own color palette, to create truecolor images, but in practice this is rarely done. Pixels are opaque, unless a specific color index is designated as transparent, in which case pixels colored that value are entirely transparent.

GIF supports simple animation, in which following an initial full-size frame, a series of images reflecting the parts of the image that change with each frame are provided. GIF has been extremely popular for decades, due to its simplicity and compatibility. Its animation support caused a resurgence in its popularity in the social media era, when animated GIFs began to be widely used for short "videos", memes, and other simple animation sequences.

Another popular feature of GIF is support for interlacing , where rows of pixels are stored out of order so that partially-received files can be displayed in lower quality. This is particularly useful when network connections are slow. GIF is a good choice for simple images and animations, although converting full color images to GIF can result in unsatisfactory dithering. Typically, modern content should use PNG for lossless and indexed still images, and should consider using APNG for lossless animation sequences.

However, early versions of Internet Explorer introduced the ability for a web site to provide a ICO file named favicon. An ICO file can contain multiple icons, and begins with a directory listing details about each.

Since the license is a big catch, not all software support it. It is much-loved by 3D printers and somewhat loved by CAM. The biggest problem with STL is that it describes only the surface geometry of a three-dimensional object without any representation of color, texture or other common CAD model attributes.

Binary files are more common, since they are more compact. Another commonly used image format is PNG. It is a raster graphics image format. It was introduced in and got an ISO standard in PNG was originally designed to transfer images ross the internet and not for printing.

That is why it only supports the RGB spectrum. Though, the format is commonly used in designing due to its transparent background. Yes, ideally, PNG supports lossless compression. It supports bit RGB colors and follows a 2-stage compression process. Though, you should know that PNG offers a compression parameter. Users can choose if they want to maintain the original quality or implement some degree of lossy compression.

Learn how to recover lost PNG files. On the other hand, PNG is a lossless compression with a compression parameter. JPG formats are used to store photographs in general. The PNG format is used to store vectors, graphics, icons, text, drawings, and other editing-related files.

This is because PNG has a transparent background and can be overlaid on another picture easily. This is something you can't do with JPEG files. The BMP file format has been around for a long time, but it has gradually lost its popularity. Let's learn what is BMP image in detail. Microsoft originally developed the format to store colored and monochrome images. It is a simple compression technique that follows a lossless algorithm.

Mostly, 4-bit or 8-bit encoding techniques are implemented via Huffman or RLE encoding. Also, not all BMP files support transparency alpha channels. BMP follows a lossless and uncompressed technique. On the other hand, JPG follows a lossy and compressed technique. The file size of JPG is far less, but the quality is also compromised in the process.

If you are a photographer, then you must have seen RAW files in your camera. So what is the RAW format? Let's uncover it here. As the name suggests, RAW files are the unprocessed photos. That is, they are the original files that are not processed by the camera yet. Since they are unprocessed, they can't be edited by the usual applications. These are the pre-conversion formats that can later be used in high-level editing like with Photoshop.

Though, they are not suitable for printing. Ideally, RAW images give us more advanced editing options. For instance, we can adjust colors, brightness, polarization, etc. This is something we can't do with JPEG files readily. It is a raster graphics format that is mostly used in the publishing domain.

It also supports image publishing, printing, and even optical charter recognition. Adobe originally developed the format in the s. When we compare JPG vs.
