Bitmap BMP is a mostly outdated image file format that maps individual pixels with little to no compression. That means BMP files can easily become extremely large and are impractical to store or handle. In theory, the compression is almost twice as efficient as JPEG, leading to images of up to double quality with identical file sizes. The Scalable Vector Graphics file format, usually referred to as SVG, was developed by W3C as a markup language to render two-dimensional images right within the browser.

Like SVG files, EPS is actually a text-based document that outlines shapes and lines with code, rather than mapping pixels and colors. As a result, EPS files also support lossless scaling. You probably associate PDF with storing, saving, and reading mostly-text based documents.

But PDF files are actually based on the same PostScript language that powers EPS vector image files and can be used to save images and illustrations as well.

As the name suggests, the PSD file format is an image format used for saving image documents and works in progress with Adobe Photoshop.

AI is another image format specifically developed by Adobe to not just save the image, but also the project state. Tired of a slow host for your WordPress site?

Although sometimes referred to as an image file format, it tends to link to visual elements beyond text. Raw image formats are the file types a digital camera uses to store full-quality images for later post-production and editing.

Rather than the shades per color channel 8 bit available in a JPEG file, RAW files offer up to 16, shades per color channel 14 bit in a single picture. That gives you more flexibility when tweaking colors and contrast in post-processing. These two factors, along with its universal browser and OS support, make it the most popular image file type on the web. Lossy means that some image quality is lost when the JPG data is compressed and saved, and this quality can never be recovered.

JPEG images: —. The format supports up to 8 bits per pixel thus allowing a single image to reference a palette of up to distinct colours. The colors are chosen from the bit RGB color space. It also supports animations and allows a separate palette of colours for each frame. The color limitation makes the GIF format unsuitable for reproducing colour photographs and other images with continuous colour, but it is well-suited for simpler images such as graphics or logos with solid areas of color.

GIF images are compressed using the Lempel-Ziv-Welch LZW lossless data compression technique to reduce the file size without degrading the visual quality. This compression technique was patented in Controversy over the licensing agreement between the patent holder, Unisys , and CompuServe in spurred the development of the Portable Network Graphics PNG standard; since then all the relevant patents have expired.

As of , it is under the control of Adobe Systems. This is a picture of a woman Pict…. Was this guide helpful? Rate this Guide! How helpful was this guide? Very Helpful. Somewhat Helpful.

However, editing requires the appropriate software. Therefore, the PSD format is often unsuitable for individuals and for collaborative work. You can work around this problem by using Adobe Photoshop and converting the file to another image file type. Conversion is also necessary before printing. With the PSD format, each image consists of several layers that can be easily edited. In principle, these files are raster graphics, but they can also contain vector graphics.

This image file format is therefore ideal for extensive image editing. Adobe Photoshop is available as part of the Adobe Creative Cloud at a cost. Free Photoshop alternatives are gaining in popularity these days, as many of them boast a similar spectrum of features.

In contrast to pixel graphics, which are fixed in size, vector graphics are much more flexible and therefore ideal for displaying geometric shapes and fonts. Lossless scaling also makes it easier to create responsive web elements. In most cases, special graphics programs are required for processing these files. Therefore, the following image file formats are usually exclusively used by graphic designers. But individuals are increasingly also taking a liking to the easily adaptable vector graphics thanks to free software alternatives.

The PDF image file format is developed by Adobe, but, unlike other Adobe formats, does not require any company-specific software although Acrobat Reader is the corresponding standard. The PDF format has established itself as a reliable exchange format and can be viewed without paid editing software — on any device, any operating system, and any web browser.

The format is particularly popular to showcase print files. With the Adobe range of programs, which are subject to a fee, PDFs can be processed in a versatile and flexible way. The foundation of this picture format particularly shows its strength for vector graphics, but also maps pixel graphics. Even in the free version, PDFs can be expanded on with additional features such as notes, comments, or file attachments.

Appropriate security settings can be used to prevent editing by third parties. The vector-based format can be scaled flexibly and offers the possibility to embed or link raster graphics. The image file format is mostly used to save logos and other marketing materials, which are required in different sizes. With Adobe Illustrator, files can also be saved in any other common image file format.

This facilitates the exchange of files between graphic designers and private individuals. Another advantage is that you can save multiple variations in a single file by hiding and unhiding layers. Among professional graphic designers this image file format has established itself as the industry standard. Today, the image format has largely been replaced by the more widely used PDF , which is also based on PostScript. EPS was the first format that made it possible to display documents exactly as they appear in print.

The most common program to open EPS files is Adobe Acrobat Reader, but there is a wide range of alternatives available. The lossless format integrates pixel and vector graphics and is characterized by a particularly high degree of adaptability and scalability.

One of the disadvantages is that EPS files are limited to one document page and do not distinguish between vector and bitmap. Since not all users, especially individuals, have access to Adobe Creative Suite, AI files are sometimes unsuitable for sharing.
