Compress PDF to 100 KB
Shrink a PDF to 100 KB or less, the strict limit on many government and exam application portals. It's a best-effort ceiling: SnapOtter shrinks the images inside the PDF, lowering resolution only as far as the target needs. A PDF that is mostly text or vector drawings has little to squeeze, and if it can't get under 100 KB the result says so and gives you the smallest version it could make.

Frequently asked questions
- Why won't my PDF go under 100 KB?
- Text and vector content barely compresses, and a long document has a floor no matter how hard the images are squeezed. The result tells you the smallest size it reached, so you know to split the file or drop pages.
- Can I compress a confidential PDF to 100 KB?
- Yes. SnapOtter runs on your own server, so the document is never uploaded to a third-party service.
