At 50 KB a one- or two-page scan can stay clearly readable, as long as the PDF is compressed the right way. This page has 50 KB set; it works out the best resolution and quality that fit.

How to Compress a PDF to 50KB

  1. Choose your PDF – a scan from the phone, a downloaded certificate or a document from DigiLocker.
  2. Target is 50 KB. Change it only if your form says otherwise.
  3. For text documents, tick Black & white; for photos or colour stamps, leave it off.
  4. Click Compress PDF and download. The new size appears before you save.

Pages vs Quality at 50KB

  • 1 page: about 50 KB per page – sharp text, even in colour.
  • 2 pages: 25 KB each – clear in black & white, fine in colour for large print.
  • 4+ pages: 12 KB or less each – small print becomes difficult; consider a larger limit or fewer pages.

Typical 50KB Documents

Caste, income and residence certificates, class 10 and 12 mark sheets, Aadhaar and PAN copies, experience letters and NOCs. Many portals ask for each one as a separate PDF under 50 KB, so compress them one after another – there is no limit.

Starting from Photos?

If your documents are JPG photos, crop each one first and convert straight to a PDF at the right size with JPG to PDF Under 100KB – type 50 KB as the maximum. That is often sharper than converting first and compressing afterwards.

Text Is Turned into an Image

Exact-size compression re-renders each page as an optimised image, so text cannot be selected afterwards. If you need selectable text and a moderate reduction, use PDF Compressor.

Private and Free
