Frequently Asked Questions
How much can I compress a PDF?▾
Photo-heavy PDFs often shrink by 60–90% using the recommended level. Text-only PDFs are already small and change little.
Does compressing a PDF lose quality?▾
Compression mainly recompresses embedded images. Text and links stay intact; choose a lighter level for print.
Is my PDF uploaded when I compress it?▾
No. The Compress PDF tool runs in your browser, so your file never leaves your device.
