Privacy & security
Do my PDFs upload to a server?
No. All tools run entirely in your browser. Your PDFs never leave your device.
How does on-device processing protect my privacy?
Every action — merging, rotating, stamping, converting — executes locally using your browser's compute. Nothing is sent to a backend, so you keep full control over sensitive documents.
Is my data tracked?
We collect minimal usage analytics such as page views when enabled. PDFs, filenames, and contents are never tracked or inspected.
Using the tools
Do I need an account?
No. All tools work without sign-up or registration.
Does OnDevicePDF work offline?
Yes. After your first visit, core assets are cached. You can continue working even without internet. Install OnDevicePDF as an app for full offline access.
Which browsers are supported?
OnDevicePDF works on all modern browsers (Chrome, Firefox, Edge, Safari). Some older browsers may have limited support.
Can I process large PDFs?
Yes, but performance depends on your device. PDFs over 100 MB may take longer to process. Consider splitting very large files first.
Are there file size limits?
No artificial limits. The only constraint is your device's available memory.
Features

No. All output is clean and watermark-free.
