Frequently asked questions
How much smaller will my PDF get?
It depends on what is inside. PDFs full of photos or scans often shrink by 40–80%. Text-only PDFs are already small and may shrink very little — if no real saving is possible, you get your original file back unchanged.
Will text become blurry?
No. Only photos and scanned images are re-compressed. Text and vector graphics are left exactly as they are, so they stay perfectly sharp.
Which compression level should I choose?
Recommended works for email and web. Light keeps images close to the original for printing. Strong gives the smallest file but images look softer.
Can I compress a password-protected PDF?
Yes. Add the file and enter its password when asked — it is unlocked in your browser first. The compressed copy is saved without a password.
Is it safe to compress confidential documents?
Yes. The images are re-compressed on your own device, so contracts, payslips and ID scans never leave it — handy when an email or upload form has a size limit.
