HOW IT WORKS
Convert JPG to WebP in your browser
WebP is a modern image format that holds JPG-level quality at a noticeably smaller file size. This tool re-encodes your JPG and JPEG files to WebP on the HTML canvas, locally, so nothing is uploaded and the smaller file downloads straight away.
Drop in your JPGs
Add one JPG or a batch of JPG and JPEG files. Each one is read and decoded locally on your device.
Set the quality
Leave it at the default or slide it to balance size against sharpness. Resize the longest side too if you want smaller dimensions.
Download the WebP files
See the new WebP size next to the original JPG, then download each file. EXIF and location data are stripped on the way out.
WHAT THIS TOOL DOES
A focused JPG to WebP converter, nothing uploaded
Everything runs on the HTML canvas in your browser, so it is fast, private and works offline once the page has loaded.
25 to 35 percent smaller
WebP keeps the same visual quality as JPG at a smaller file size, so pages load faster and use less bandwidth.
Quality you control
Set the WebP quality, with the new size shown next to the original JPG so you can see the saving for yourself.
Resize while you convert
Cap the longest side to 1920px or any width you choose, to change format and dimensions in a single pass.
Many JPGs at once
Drop a whole folder of JPGs in together. Each is converted to WebP and downloaded one by one.
Supported everywhere
Chrome, Firefox, Safari and Edge all display WebP, so it is safe to use across the modern web.
Nothing leaves your device
No upload, no account, no queue. Your images are processed locally and re-encoding strips EXIF and GPS metadata.
