Understanding the Different Image Formats for Coding

Did you know GIF is the oldest graphic format? It is the most widely supported image format on the web since 1987.

It has plenty of weaknesses, however. It spurred the next generation of image formats to fix the issues. Now, we have JPEG, PNG, and more.

These formats allow us to use high-quality images, depending on usage. What are the most common ones in coding? Keep on reading to learn more about the different image file types.

JPEG

JPEG is one of the most popular image formats, more commonly used in digital cameras. It’s a solid choice for lossy compression since it can achieve 10:1 data compression with minimal loss in quality.

Its creators made JPEG 2000 to serve as an improved version. It delivers lossless data compression, producing higher-quality images. However, it’s not as popular as the original as fewer software applications support it.

PNG

For a more precise reproduction of source images, PNG is the preferred option. It supports lossless compression and 16 million colors. Images are bulky in this format, but it’s best for web designers because of transparent backgrounds.

GIF

GIF has a slightly better compression ratio than PNG, allowing for transparency. It supports both still and animated image files.

The main reason for its popularity is you can create motion graphics with it. You can then upload the file as an image. 

As an image file type, it allows you to use tools for images. For instance, you can extract the text using OCR in C#.

AVIF

AVIF is a high-performance format that supports both images and animation. It has much better data compression than PNG and JPEG. It supports transparency and higher color depths, but it has limited browser support.

WebP

WebP offers superior lossy and lossless data compression. It produces 26 to 34 percent smaller images than JPEG, making it better for web development and coded images.

Like AVIF, this file format supports transparent backgrounds and animated frames. Still, it has better browser support.

SVG

SVG is a web-friendly vector image format composed of mathematical formulas based on lines and points. It’s the perfect choice for logos and diagrams since it doesn’t lose quality after resizing. 

XML text files define the behavior of SVG images. You can edit them using any text editor and drawing software.

EPS

EPS is a vector image format with both text and images. It’s the best choice for professional and high-quality printing, such as billboards and large posters. For this reason, you can convert it to bitmap formats using Adobe Illustrator.
