How to compress a PDF to 100 KB

We tested it: three PDFs compressed to 100 KB

Tested on October 28, 2026 with a CV with a photo (3 pages, 1.3 MB), a phone scan of a certificate (4 pages, 1.3 MB) and a brochure full of photos (6 pages, 3.6 MB). ppi: pixels per inch of the redrawn pages.

CV, 3 pages90 KB72Clear
Scan, 4 pages88 KB61Readable, a little soft
Brochure, 6 pages84 KB58Readable, a little soft

At 100 KB the 4-page scan reads as “readable, a little soft” at 61 ppi: for small print, send fewer pages. In Black and white it came out at 87 KB instead of 88 KB, at the same 61 ppi, so keeping colour costs almost nothing.

A text document of two to four pages usually fits under 100 KB. In our test a 4-page phone scan fitted too and stayed readable, though slightly soft; two or three pages stay crisp. How the PDF compressor works.

A 100 KB cap is common for supporting documents on recruitment, admission and scholarship portals: caste, income and domicile certificates, an ID card, or a single mark sheet. It is a tight limit, so these forms almost always expect one page per upload. See the official limits for SSC, IBPS, SBI, NEET, JEE and GATE.
