Is it safe to upload confidential legal documents to ConvertHub?

Yes, 100%. All uploads are encrypted with end-to-end 256-bit SSL encryption. We enforce zero data logging and permanently auto-purge all files from our servers after 2 hours.

How many PDF files can I merge together for free?

You can merge unlimited PDF files up to a combined size of 50 MB completely free without registering or providing an email address.

How does PDF compression reduce file size without losing text sharpness?

Our compression engine removes orphaned font descriptors, deduplicates internal object streams, and re-encodes embedded raster images at optimized DPI (72 or 150 DPI) while keeping vector text 100% crisp.

Can I unlock a password-protected PDF file?

Yes. If you know the password, ConvertHub decrypts the document and provides an unlocked copy with all printing and editing restrictions permanently removed.
