Compress PDF — Free, No Signup

Reduce PDF file size while preserving quality. Preserve text & forms for a clean re-pack, or re-render as image for maximum compression. If a pass would not shrink the file, you get your original back — never worse. No signup required.

How it works

1. Upload a PDF: Any PDF you want to shrink — nothing is uploaded to a server.
2. Pick a compression mode: Preserve text & forms for a clean re-pack, or re-render as image for maximum size reduction.
3. Download the smaller file: If a pass wouldn’t actually shrink the file, you get your original back — never a worse result.

Frequently asked questions

How is this different from Smallpdf or ILovePDF?
Those upload your PDF to a server; this compresses it entirely in your browser, and guarantees you never receive a larger file than you started with.

Will compressing lose text or form fields?
The "preserve text & forms" mode is designed specifically to keep those intact while still reducing size; the image-re-render mode trades text/forms away for maximum compression on scan-heavy PDFs.

Is my PDF uploaded anywhere?
No — compression runs entirely on-device.
