Frequently Asked Questions

How does PDF compression work?
PDFs are uploaded over HTTPS to our server, processed by Ghostscript at the chosen quality setting, then the compressed file is served for download. Files are deleted immediately after.
Will text become unreadable after compression?
No — text in PDFs is vector-based and stays perfectly sharp at any compression level. Only embedded images are quality-reduced.
What is the maximum PDF file size?
Up to 100MB per file.
Is it safe to compress confidential PDFs?
Yes — files are transmitted over HTTPS, processed immediately, and deleted from our server after download. We never store or read your documents.
