FAQ
Are my PDFs uploaded to a server?
No. Compression runs entirely in your browser (client-side) for maximum privacy.
Will quality be affected after compression?
You can choose Low, Medium, or High levels. For images, Lossy (JPEG) usually gives smaller sizes, while Lossless (PNG) preserves quality better but may be larger.
Can I compress multiple PDFs at once?
Yes. Add several files to the list and process them together. You can also download them as a ZIP.
Is there a maximum file size?
Limits depend on your device memory and browser. Because processing is local, very large PDFs may require more RAM.
Do you support password-protected PDFs?
Encrypted PDFs are not supported unless unlocked by the user first.
Is the tool free forever?
Yes. It’s 100% free and privacy-first. No account or sign-up required.
