Frequently Asked Questions

Is my PDF uploaded to your server?

For PDF processing, files are temporarily processed server-side and deleted immediately after. No copies are retained.

How much can PDF compression reduce file size?

Depending on content, files with embedded images can shrink by 50–90%. Text-only PDFs typically reduce by 20–40%.

Does compression affect text quality?

No. Text in PDFs is not affected by compression. Only embedded images and metadata are optimised.
