WebP

The WebP image format

WebP makes images lighter for the web. It handles photos and graphics, supports transparency and animation, and works in all current major browsers.

What it is

WebP is an image format introduced by Google in 2010. Its lossy mode is based on the VP8 video codec, and a separate lossless mode was added later. Both modes support transparency, and WebP files can also be animated.

The goal of WebP is simple: smaller image files for faster web pages. For photos, a lossy WebP is usually noticeably smaller than a JPG of similar visible quality. For graphics, lossless WebP is often smaller than PNG.

Strengths

  • Small files. Lighter than JPG for photos and often lighter than PNG for graphics.
  • One format for many jobs. Lossy and lossless modes, transparency and animation in a single format.
  • Browser support. All current major browsers display WebP.
  • Fast encoding. Creating WebP files is quick, which matters for large batches.

Weaknesses

  • Outside the browser, support varies. Some older programs, image viewers and many official upload forms still accept only JPG and PNG.
  • 8 bits per channel. WebP does not support high bit depths or HDR, unlike AVIF.
  • Maximum size. A WebP image can be at most 16383 pixels wide and high.
  • Reduced color detail in lossy mode. Fine colored details, such as thin red text, can look soft.

When to use it

WebP is a strong default for images on your own website: photos, product images, illustrations and banners. For the smallest possible photos, AVIF can do even better, and many sites serve both. The WebP vs AVIF guide explains the differences. For images that you send to other people or upload to forms, JPG remains the safer choice.

How to open and convert WebP

Current browsers open WebP files directly, and recent versions of Windows and macOS can usually preview them. When a program or form refuses a WebP, convert it.

  • WebP to JPG or PNG: the WebP to JPG converter saves JPG by default or PNG on request. Transparent areas are filled with a background color when saving JPG. For animated WebP files, only the first frame is saved.
  • Images to WebP: the WebP converter turns JPG, PNG and other images into WebP. It uses the browser's encoder, which is lossy; transparency is kept.
  • WebP to AVIF: the AVIF converter for even smaller files.
  • WebP to PDF: the image to PDF tool combines images into a document.
  • WebP to ICO: the PNG to ICO converter also accepts WebP files.

Conversion happens in your browser, so your images are not uploaded.

Frequently asked questions

Why do images I save from websites end up as WebP?

Many websites deliver WebP to browsers that support it, sometimes even when the address ends in .jpg. Saving the image gives you the WebP data. Convert it with the WebP to JPG converter if you need a JPG.

Is WebP lossless?

It can be. WebP has both a lossy and a lossless mode. Most WebP images on the web use the lossy mode because it gives the smallest files for photos.

Will converting WebP to JPG reduce quality?

JPG is lossy, so a tiny amount of detail is lost. At a quality of 85 or more, the difference is very hard to see.
