Compress WebP Images

Processed on your device — files are never uploaded.

WebP vs. AVIF

WebP is fast to encode and decode and works in all current browsers. AVIF can be 20–30% smaller again for photos but is slower to encode. Choose AVIF in the format picker when every kilobyte counts.

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.
