How to convert images to or from WebP
- Add your images: JPG, PNG, GIF, AVIF, HEIC or WebP, as many as you like.
- Choose the output format. Pick WebP to make images smaller for a website, or JPG or PNG to convert WebP images into a format every program can open.
- Set the quality for WebP or JPG. 75–85 is a good balance for websites. PNG output is lossless, so the quality setting is hidden.
- Download the converted files one by one or as a ZIP.
What is WebP?
WebP is an image format created by Google for the web. It can be lossy like JPG or lossless like PNG, supports transparency like PNG, and even supports animation like GIF. Its main advantage is size: according to Google, lossy WebP images are 25–34% smaller than JPGs of comparable quality, and lossless WebP images are about 26% smaller than PNGs. Every current browser displays WebP, including Safari since 2020.
| Format | Compression | Transparency | Best for |
|---|---|---|---|
| JPG | Lossy | No | Photos, maximum compatibility |
| PNG | Lossless | Yes | Screenshots, logos, text, graphics |
| WebP | Lossy or lossless | Yes | Websites: photos and graphics |
| AVIF | Lossy or lossless | Yes | Websites, even smaller but slower to encode |
| GIF | Lossless, 256 colors | Yes (on/off) | Simple animations |
Why use WebP on your website?
Images are usually the heaviest part of a web page. Smaller images load faster, especially on mobile data, and page speed is one of the signals in Google's Core Web Vitals, particularly Largest Contentful Paint (LCP), which is often an image. Converting a site's JPG and PNG images to WebP is one of the simplest speed improvements available, and it doesn't require changing the design.
For best results, resize images to the size they're actually displayed at before converting (the image resizer does both in one step), and serve them with an <img> tag that sets width and height to prevent layout shift.
Why convert WebP to JPG or PNG?
Images saved from websites are often WebP. Some older software, print services, document editors and upload forms still don't accept them. Converting to JPG gives you a photo that works everywhere; converting to PNG keeps sharp edges and transparency for logos and graphics.
A note about Safari
Safari can display WebP but, for now, can't create WebP files from a web page. On Safari you can still convert WebP to JPG or PNG. To create WebP files on a Mac or iPhone, use Chrome, Edge or Firefox.
Animated GIF and animated WebP files are converted using their first frame.
Frequently asked questions
Is WebP better than JPG?
For websites, usually yes: WebP gives similar quality at a 25–34% smaller size and also supports transparency. JPG is better when you need a file that every program and device can open.
Does converting WebP to JPG lose quality?
Re-encoding a lossy image always discards a little detail, but at quality 85–90 it's not noticeable. Choose PNG if you need to avoid any additional loss.
Why does my converted PNG have a larger file size?
PNG is lossless and stores every pixel exactly, so a photo saved as PNG is much larger than the same photo as WebP or JPG. Use PNG for graphics and screenshots, not photos.
Can I convert animated GIFs to WebP?
This tool converts the first frame of an animation to a still image. Animated conversion isn't supported yet.
Do all browsers support WebP?
All current versions of Chrome, Edge, Firefox, Safari, Opera and Samsung Internet display WebP images.
