Frequently asked questions

Clear answers about privacy, offline use, and how OnDevicePDF works.

Quick answers

  • Works offline once loaded.
  • No accounts. No watermarks. Free to use.

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

Which browsers are supported?

We support current versions of Chrome, Edge, Firefox, and other Chromium-based browsers on desktop and mobile.

Can I use OnDevicePDF offline?

Yes. Once loaded, most tools work offline. Installing the app caches key assets for continued use without internet access.

Is there a file size limit?

There is no hard limit. Performance depends on your device memory. Very large PDFs may take longer to load or process.

How do I reset if something gets stuck?

Refresh the page or reopen the tool. Because nothing is stored on servers, reloading clears the current session.

Pricing & access

Is OnDevicePDF free?

Yes. No sign-up required, and we don’t add watermarks.
