JPG to WebP
WebP typically produces noticeably smaller files than JPG at the same visual quality, which makes it a good default for website images. This tool converts JPG photos to WebP with a quality control.

Why use JPG to WebP?
Images arrive in whichever format the camera, phone or app happened to produce, and that is rarely the format you need next. Converting and resizing lets you meet an upload limit, strip a format a website refuses, keep a transparent background where it matters, or cut a photo from several megabytes down to something an email will accept — without losing the original, which stays untouched on your device.

Your privacy
This tool runs entirely in your browser using JavaScript and WebAssembly. The file you select is read into your device's memory, converted there and offered back as a download — it is never uploaded to our servers. Closing or reloading the page clears it. If you are signed in, we store only the tool name, the number of files and their total size so you can see your own activity history; the file contents are never sent.
Tips for the best result
- Start from the highest-quality original you have; converting an already-compressed file twice loses detail.
- If you need transparency, keep the output in PNG or WebP — JPG cannot store an alpha channel.
- When resizing for the web, set the width you actually display at rather than shrinking a huge image in CSS.
- Compress last, after cropping and resizing, so you are not re-encoding the same pixels repeatedly.
Frequently asked questions
Is WebP supported by all browsers?
All current versions of Chrome, Edge, Firefox and Safari support WebP. Very old browsers may not.
How much smaller will the files be?
It depends on the image, but a 25–35% reduction at comparable quality is common for photographs.
Can I convert back later?
Yes, use the WebP to JPG or WebP to PNG tool. Note that each re-encode loses a little quality.
Are files uploaded?
No. The conversion runs in your browser with JavaScript and WebAssembly, so the file never leaves your device and nothing is uploaded to our servers.
