FAQ
How much will the file size be reduced?
It depends on the PDF content. Image-heavy PDFs typically see 40-70% reduction. Text-only PDFs may see minimal change.
Will the quality be affected?
Images inside the PDF are re-encoded at the selected quality level. Text and vectors remain sharp at any setting.
Is my file sent anywhere?
No. Processing happens entirely inside your browser using WebAssembly. Nothing is uploaded.
Can I compress a password-protected PDF?
Not directly. First remove the password using our Unlock PDF tool, then compress it.
Is there a file size limit?
Maximum 100 MB per file. Larger files may be slow depending on your device.
