Compress PDF
Make your PDF smaller while keeping the pages clear and readable.
Leave empty for default compression. Example: 5 MB PDF → type 2500 KB or 2.5 MB.
What is PDF compression?
PDF compression rewrites a PDF so it takes less storage space, usually by optimising images and repeated data inside the file. It matters when an application portal caps uploads at a few MB, or when a big report keeps bouncing back from email. A smaller file uploads faster, downloads faster and uses less mobile data.

Frequently Asked Questions
How much smaller will my PDF become?
It depends on the file. PDFs full of photos usually shrink a lot, while text-only PDFs shrink less. The tool balances size against readability so pages stay usable.
Is it free to compress a PDF here?
Yes. Upload your PDF, compress it and download the result without paying or signing up. Processing happens on the server.
Will compression blur my document?
The goal is a smaller file that still reads well. Text stays sharp in most cases, though very heavy image pages may show slight softening.
Can I compress a scanned PDF?
Yes, scanned PDFs can be compressed too. Results vary with scan quality - clean scans at reasonable resolution compress best.
