Frequently Asked Questions
Will compression make my PDF unreadable?
No. Balanced compression keeps text sharp and images clear. It’s optimized for sharing while maintaining readability.
Can I compress multiple PDFs for email at once?
Currently, we process one file at a time. However, you can use our Merge PDF tool first to combine files, then compress the merged document.
Is there a limit to how much I can compress?
No file size limits. The tool works entirely in your browser, so it depends on your device's memory. We recommend files under 500MB for best performance.
