Get a photo under 100 KB without losing clarity

The compressor tries quality levels from high to low and keeps the best one that fits under 100 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 100 KB limit is common

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

  • Scanned certificates and marksheets uploaded as images
  • University and college admission portals
  • Job applications that accept JPG documents

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.

Open this page in Chrome or Safari, tap the upload box, choose your photo and tap Compress. A JPG of 100 KB or less downloads straight to your phone.

Will the photo be blurry?

No for typical passport-size photos. 100 KB is enough for a clear face photo at the dimensions portals expect.

Can I compress a PNG to 100 KB?

Should I use JPG or PDF for documents?

Use whatever the portal asks for. If it needs PDF, convert the compressed JPG with our JPG to PDF tool.
