Your files are processed entirely in your browser and never sent to our servers.
Reduce PDF file sizes for easier email attachments, faster uploads, and cheaper storage. Compression removes metadata and recompresses embedded images while keeping text perfectly sharp.
Compression levels
| Level | Typical reduction | Best for |
|---|---|---|
| Low | 10–25% | Print-quality, archival PDFs |
| Medium | 30–55% | Email attachments, general use |
| High | 55–80% | Web downloads, large photo-heavy PDFs |
Pros and cons of PDF compression
Pros
- Much smaller file size — email-friendly
- Faster to upload and download
- Text remains perfectly sharp
- Cheaper to store in bulk
Cons
- Embedded images may look slightly softer at high compression
- Some interactive elements (forms, JS) may be stripped
- Digitally signed PDFs lose their signature after compression
Frequently asked questions
How much can you reduce a PDF?
PDFs with many high-resolution images can shrink by 50–80%. Text-only PDFs compress much less — typically 10–30% — because text is already efficiently stored.
Does compression affect text?
No. Text remains perfectly sharp and fully searchable. Only embedded images are recompressed.
Is there a size limit?
You can compress PDFs up to 50 MB for free.
Will form fields and links be preserved?
Yes, form fields, internal links, and bookmarks are preserved. Digital signatures are invalidated by compression (this is how all PDF compressors work).
