Frequently asked questions

How much can I compress a PDF?

It depends on the content — pages with a lot of text and detail compress less than photo-heavy pages. The tool rasterizes pages and binary-searches quality until it hits your target size, or reports the smallest size it could reach.

Will compressing lose quality?

Compression rasterizes each page (text becomes an image), so it's best for hitting a size limit — like a portal upload cap — rather than for a document you'll edit later.

Is my file uploaded to compress it?

No. Compression runs entirely in your browser using client-side JavaScript — nothing is sent to a server.
