Frequently asked questions
How much smaller will my PDF get?+
It depends on the content. PDFs with photos or scans often shrink by 50–90%. Text-only PDFs are already small and change less.
Will compression reduce quality?+
Balanced keeps documents sharp on screen and in print. Strong makes images smaller with some visible loss — ideal for email.
Can I compress to a specific size?+
Yes. Set a target such as 1 MB or 500 KB and we’ll aim for it automatically.
Are my files uploaded?+
No. Compression runs in your browser, so your PDF never leaves your device.
