Frequently asked questions
Will compression reduce PDF quality?
No. The tool optimizes the internal structure of the PDF and recompresses images without changing their visible resolution. Text and vector graphics remain perfectly sharp.
How much smaller will my PDF be?
Typical reductions range from 30% to 70%, depending on how many images the PDF contains and their current compression level.
Is there a file size limit?
There is no practical limit. PDFs are processed in chunks locally in your browser, so even 100+ MB files work fine.
Is my PDF uploaded to a server?
No. The entire compression process happens locally in your browser. Your document never leaves your device.
