Questions

Frequently Asked

Are my files safe?
Yes — 100%. All processing happens locally in your browser using JavaScript. Your files are never uploaded to any server. We can't see them even if we wanted to.
Is there a file size limit?
No hard limit from our side, but very large files (100MB+) may be slow depending on your device's RAM and CPU. Most images work instantly.
Does it work offline?
Once the page is loaded, all tools work offline since processing is done locally. You only need internet to load the page initially.
Will it add a watermark?
Never. AIFreePDF adds no watermarks, no branding, no hidden metadata. What you compress is what you get.
