About PDF Compressor

Compression can reduce the size of scanned images and other heavy PDF content. The reduction depends on what is already in the source file.

Stronger settings may soften photos or scans. Digital text often remains readable, but always inspect fine print, signatures and diagrams in the result.

This tool uploads the PDF for server-side processing. Temporary input and output files are scheduled for cleanup after two hours.

Frequently Asked Questions

Which setting should I try first?

Start with Medium. If the file is still too large, try Strong and compare readability. If the file is already optimized, the size may barely change.

Will text or images lose quality?

Compression can affect scanned pages and photos. Open the output and inspect important details before using it.

Can I compress an encrypted PDF?

You may need to unlock a password-protected PDF before the tool can process it.

Are documents uploaded to a server?

Yes. Compression runs on our server. Temporary input and output files are scheduled for removal after two hours; avoid uploading sensitive files if server processing is unsuitable.
