Which Format Is Best For Website Images? JPEG, PNG, GIF, or SVG

Images on the web come in many formats but if you go for a wrong format, you might end up with a slow-paced website, lower conversion rates, and higher bounce rates. And since Google hates the pages that load slowly, improving load time in one thing to make it happy. It impacts the website’s ranking which is a part of SEO strategy to gain more visitors

Each has advantages and drawbacks, and knowing which to choose can make a big difference in how your website design looks to visitors.

In this blog, We’ll go over the old favorites, JPEG, PNG, and GIFs and some of the next-gen ones like WebP and SVG.

JPEG, PNG, GIF, or SVG Image File Format

JPEG image file format

JPEG: JPEG stands for “Joint Photographic Experts Group”. It is an image saved in a compressed graphic format. The end result is a reduced size image that contributes to faster page loading but this benefit comes at the expense of quality. To compress the image when saved, the JPEG format sacrifices some of the information it contains, that’s why the format is called “lossy.” Besides image information, JPEG images files may also contain metadata that describes the contents of the file.

PNG image file format

PNG: PNG stands for “Portable Network Graphics“, with so-called “lossless” compression. This file format was designed specifically for transferring images on the Internet rather than for print graphics. Just like JPEG even PNG supports millions of colors, although you’re much better off using PNGs for images that contain fewer color data. The big plus point for using PNG is that this type of image format can be completely transparent which is important for png logo designs and similar. There are three kinds of PNGs: PNG-8, PNG-24, and PNG-32

JPEG vs PNG – Lossy or Lossless

Since both the image formats have their own pros and con, you should get the most of both formats.

In practice, it means that you should make use of .jpeg for photographs, and .png for graphics and screenshots to keep the balance.

At the end of the day, if you still have doubts about choosing the right image format for you, you can save a picture in both the image formats and then compare them and decide which one you think fits your needs best.

Let’s Move to other image formats

GIF: GIF stands for “Graphics Interchange Format”. It is basically an image file format that is animated by combining several other images or frames into a single file. You can optimize GIF files, but in most of the cases, the final version won’t be as good as the other image formats. GIFs have a limited color palette of 256 colors and use lossless compression. These are best for small web graphics, icons, buttons, and navigation images. Use GIFs only when you need to showcase an animation you can’t create any other way

SVG: SVG stands for “Scalable Vector Graphics”. They are not actually an image file format instead they are more like HTML than PNGs or JPEGs. SVGs were designed to display simple images based on geometric shapes, such as logos, flags, charts, and icons. Even though it is kind of a markup language, Google understands SVGs that’s why they are indexed by google. Moreover, they are compatible with all popular browsers. You can create SVGs in a vector program like Adobe Illustrator, Sketch, SVG-edit, Vectr, or Inkscape.

Important Note To Read Before Choosing Between JPEG & PNG:

JPEG Format Images are smaller and faster to load but the compression hurts the image quality. It is usually not a problem for photographs, but it can act bad for text or images containing a fine line.


PNG, on the other hand is the best option for screenshots, graphs, pics with text,  and designs that require the use of transparency, such as logo designs and similar. However, the biggest problem here is that PNG is greater in size and will surely slow down your website.
