Steps on Android and iPhone

  1. Open the 50 KB tool in Chrome or Safari.
  2. Tap the box and pick a photo from your gallery or camera.
  3. Wait a few seconds while it compresses on your phone.
  4. Tap Save. The file lands in your Downloads (Android) or Files app (iPhone).

Why it doesn’t need an upload

MediaShift runs FFmpeg, a widely used media engine, inside your browser using WebAssembly. Your photo is processed by your phone itself, so it works for private documents and even without a stable connection once the page has loaded.

Other common sizes

  • 20 KB: signatures and strict government forms.
  • 100 KB: most job and university portals.
  • 200 KB and 500 KB: email attachments and websites.

Questions

Do I need to install an app to compress a photo to 50 KB?

No. MediaShift works in the phone’s browser, with no app to install.

Will compressing to 50 KB make my photo blurry?

MediaShift finds the highest quality that fits under 50 KB and only reduces the dimensions if it must, so most photos stay sharp.
