Compress Image to 50 KB

Drop a photo or scanned signature below — it is compressed to under 50 KB automatically, the limit many exam, visa and job portals use. The file is processed on your device.

Processed on your device — files are never uploaded.

How to compress image to 50 KB

  1. Drop your photo or signature scan.
  2. Keep the 50 KB target.
  3. Compress.
  4. Download.

Signatures and documents

For signatures, crop tightly first. A small, high-contrast image can be very sharp at 20–50 KB. For portrait photos, 600–800 px wide is plenty.

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.
