Convert JPG to WebP

Drop JPG images below to convert them to WebP — usually 25–35% smaller than the original JPG at similar quality, with full browser support. Convert in bulk and download a ZIP.

Processed on your device — files are never uploaded.

How to convert JPG to WebP

  1. Drop JPG files.
  2. Keep WebP selected.
  3. Compress.
  4. Download WebP files or ZIP.

Should I use WebP on my website?

Yes. Every major browser supports WebP, and smaller images improve Largest Contentful Paint, a Core Web Vitals metric. Use a <picture> element if you need a JPG fallback for very old software.

Private by design

ShrinkVid never uploads your files. The page loads once, then all decoding and encoding happens on your device using the browser’s built-in WebCodecs API (hardware-accelerated video) and WebAssembly image codecs. That makes it safe for personal, confidential or work files — and there is no queue, no file size cap and no watermark. Read how it works.

Frequently asked questions

Are my files uploaded to a server?

No. ShrinkVid runs entirely in your browser. Files are read and encoded on your own device with WebCodecs and WebAssembly, so nothing is uploaded, stored or seen by anyone else. You can even disconnect from the internet after the page loads and it keeps working.

Is it really free? Is there a watermark or file size limit?

It is completely free with no watermark, no sign-up and no server-side file size limit. Because processing happens on your device, the only practical limits are your device’s memory and speed.
