How to compress WebP files online
Add your WebP files
Drop WebP files into the box, choose them from your device, or paste them from your clipboard. You can add hundreds at once.
Compress WebP privately on your device
Each WebP is encoded again on your device with more effort, at the lowest quality that still looks the same. Transparency is kept.
Download your smaller WebP files
Save each file on its own, or take them all in one ZIP. Your files stay private: they never leave your device, so there is no upload to wait for.
How WebP compression works
WebP is already one of the most efficient formats, so the saving is smaller than for a JPG or PNG. Files exported with a quick default setting can still shrink noticeably when they are encoded again with more effort.
Sanil.app picks the smallest file that still looks the same and keeps transparency. The result is a WebP, so it loads fast in every current browser.

Questions about compressing WebP files
How much smaller will it get?
Less than a JPG or PNG would, because WebP is already efficient. The biggest savings come from files that were exported quickly or straight from a camera app.
Do all browsers open WebP?
Current versions of Chrome, Firefox, Safari and Edge do. Some older apps and email programs don't, so keep a JPG or PNG copy for those.
Is transparency kept?
Yes. A WebP with a transparent background stays transparent.
Should I use WebP or JPG on my website?
For a website, WebP is usually the better choice: it stores a photo in less space than a JPG at similar quality, and every current browser opens it. Keep a JPG for email attachments, print shops and older apps.
Are my WebP files private?
Yes. Sanil.app compresses your WebP files on your device, so they are never uploaded and never reach a server. They stay yours.
