Frequently asked questions
How do I compress a PDF and reduce its size?+
Upload the file, choose a compression level, and click "Compress PDF". We'll show the new size, then you download it.
How much smaller will the file get?+
Scans and PDFs full of photos shrink dramatically. A text or vector document is already tightly packed, so the gain there is modest.
Does the text stay selectable after compression?+
Yes. Compression run via background WASM worker, and pages aren't converted to images, so the text layer stays intact: selection and search still work.
Do the files get uploaded to a server?+
No, everything is processed in your browser. The file is never uploaded anywhere.
Is it free?+
Yes, no signup and no watermarks.
