How to compress a PDF to 400 KB
- Choose your PDF. Pick it or drop it on the box.
- Check the size. 400 KB is already selected; choose another from the list if your form allows more or less.
- Compress. The smaller PDF downloads straight away, and the status line shows the new size.
We tested it: three PDFs compressed to 400 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.
| After | ppi | How it reads | |
|---|---|---|---|
| CV, 3 pages | 383 KB | 150 | Sharp, small print too |
| Scan, 4 pages | 365 KB | 120 | Sharp, small print too |
| Brochure, 6 pages | 366 KB | 120 | Sharp, small print too |
At 400 KB the 4-page scan reads as “sharp, small print too” at 120 ppi. In Black and white it came out at 364 KB instead of 365 KB, at the same 120 ppi, so keeping colour costs almost nothing.
Typed documents of fifteen pages or more, or about ten scanned pages, fit under 400 KB. How the PDF compressor works.
How many pages fit in 400 KB?
| Pages | 400 KB |
|---|---|
| Typed pages (no photos) | 15+ |
| Scanned pages, still clear | 10 |
A 400 KB limit is common on job and finance portals for supporting documents: a CV with certificates, a few pages of bank statements, salary slips, or an address proof scanned front and back. See the official limits for SSC, IBPS, SBI, NEET, JEE and GATE.
Tips for a clear, small PDF
- Download statements as PDFs from your bank rather than scanning paper copies; they are far smaller.
- Salary slips and letters made on a computer rarely need more than lossless compression.
- Scans: about ten pages fit; Black and white barely changes that.

Can I fit bank statements under 400 KB?
Usually, yes. Statements downloaded as PDFs from a bank are text, so several months compress without any loss. Scanned paper statements fit about ten pages and stay clear.
