Get a photo under 20 KB without losing clarity

The compressor tries quality levels from high to low and keeps the best one that fits under 20 KB. Only if quality alone isn't enough does it shrink the pixel dimensions slightly. The output is always a JPG, the format nearly every Indian exam and government portal requires.

Where a 20 KB limit is common

Exact limits change with every notification, so always check the official instructions for your exam or portal before uploading.

  • Signatures on recruitment and exam applications
  • Photos for some SSC, railway and state-level forms
  • Thumb impressions and small ID scans

Before you upload

  • Crop to the required shape first (passport photos are usually taller than wide)
  • Use a plain light background and even lighting
  • Check whether the portal also asks for exact pixel dimensions or a date on the photo
  • Keep the original — compress again with a different target if the portal rejects it

Private by design

Files are uploaded over HTTPS, processed on our own servers in India and deleted automatically as soon as your download starts. We do not keep copies, add watermarks or ask you to sign up.

Frequently asked questions

How do I compress a photo to 20 KB on my phone?

Open this page in Chrome or Safari, tap the upload box, choose your photo and tap Compress. A JPG of 20 KB or less downloads straight to your phone.

Will the photo be blurry?

No for typical passport-size photos. 20 KB is enough for a clear face photo at the dimensions portals expect.

Can I compress a PNG to 20 KB?

Yes. PNG, WebP and GIF are converted to JPG automatically, with any transparent background turned white.

My signature still looks too big — what can I do?

Crop tightly around the signature before uploading, sign with a dark pen on white paper, and scan or photograph in good light.
