Compress PDF online

Adjustable quality in your browser: high quality repacks only (good for text). Lower quality rasterizes each page as JPEG—much smaller for scans and image-heavy PDFs, but text may look soft.

Pages are rasterized and JPEG-compressed—smaller files, but text and thin lines may look soft. Use ~92%+ for repack-only if you need sharp text.

FAQ

Is my PDF uploaded?
No—loading and saving happen in your browser.
Why is it still large?
At high quality we only repack and strip metadata—embedded images aren’t resampled, so size may barely change. Lower the quality slider to rasterize pages as JPEG; scans and photo-heavy PDFs shrink a lot, but body text can look softer. Pick what fits your document.
Password-protected PDFs?
Some encrypted files can’t be processed. Decrypt locally or export an editable copy first.
