PDF Compressor
Drop your .pdf files to compress entirely in your browser. Use the single Quality slider. Never-worse: if our output isn’t smaller, we keep your original.

We process per-page for stability.
Compression
Higher = bigger file, lower = smaller file. We automatically prevent size increases.
Why compress PDFs?
Smaller PDFs upload faster and save bandwidth. This tool lets you adjust a single quality slider, optionally do lossless cleanup for tiny/text files, or run an advanced WASM pass that keeps vectors and text intact.
Tips
- Try Lossless cleanup for small text-only docs.
- Use Advanced for slide decks or vector-heavy PDFs; it preserves selectable text.
- We never upload files—everything runs in your browser.
FAQ
Do you upload or store my PDFs?
No. Everything runs locally in your browser. Nothing leaves your device.
Will text and vectors be preserved?
Yes when Advanced is enabled—it uses a WASM Ghostscript pass that retains text/vectors while recompressing images.
