Compress PDF to 100 KB
Drop in a PDF and it comes back under 100 KB, at the best quality that fits. It tries the text-preserving levels first and only turns pages into images when nothing else gets the file small enough.

What fits at this size
| What you are uploading | Fits in 100 KB? |
|---|---|
| Text-only PDF from Word, up to about 20 pages | Usually yes, with text still selectable |
| 1–2 page scan in black and white | Yes, pages become images |
| 3–5 page colour scan | Only at low sharpness; check it is readable |
| Photo-heavy brochure | Rarely readable; split it or send fewer pages |
Before you submit
- 100 KB is one of the tightest limits in common use. A single colour phone scan is often 1–3 MB before compression.
- If the result is blurry, rescan in grayscale at 150 DPI, or upload only the pages the form asks for with the Page Extractor.
- Blank back pages from a duplex scan cost as much as real ones. Remove them first with the Page Remover.

❓ Frequently Asked Questions
Common Questions
The text-preserving levels could not reach 100 KB, so the pages were saved as images. The page looks the same, but you cannot copy text from it. If you need selectable text, reduce the page count instead.
You get the smallest version it could make, with its size shown. Remove pages, or scan in grayscale at a lower resolution, then try again.
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.
