Compress PDF to 300 KB
Bring a PDF under 300 KB at the best quality that fits. That is room for a few clear scanned pages or a long typed document, without guessing at a compression level.

What fits at this size
| What you are uploading | Fits in 300 KB? |
|---|---|
| Typed PDF, up to about 50 pages | Usually yes, text stays selectable |
| 2–4 page colour scan of certificates | Yes, with seals and stamps legible |
| Mark sheets for several semesters in one file | Often; check every page's grades are readable |
| Scanned book chapter of 20 or more pages | Too blurry at this size; send fewer pages |
Before you submit
- Every attempt starts again from your original file, never from the previous attempt, so quality is only lost once.
- When a form takes several documents with 300 KB each, compress them one at a time. Merging them first makes all the pages share a single 300 KB.
- A typed PDF that fits keeps selectable text, which matters when a portal or a recruiter searches inside it.

For two to four pages, yes in most cases. Zoom into the seal, the signature and the smallest print in the result before you submit.
The text-preserving levels could not reach 300 KB, so the pages were saved as images. The pages look the same, but text cannot be copied. Remove pages if you need it selectable.
It varies, so the tool aims about 3% under the upper limit and, where there is a lower limit, just above it in 1,024-byte KB. The file is accepted either way.
