Frequently Asked Questions
How much can PDF compression reduce file size?
Typically 20–70% reduction depending on content. PDFs with many high-resolution images compress the most. Text-only PDFs may compress less.
Will compression affect text quality?
Text quality remains sharp after compression. Only embedded images are compressed, not the text itself.
Is it safe to compress important documents?
Yes. Compression only reduces file size and never alters text content or meaning. We recommend keeping the original as a backup.
