Are my files uploaded?

No. On Free, files stay in your browser and are gone when you close the tab. Nothing is sent to a server unless you use the API, CLI, MCP, or apps.

Do bookmarks and forms stay?

Pages, size, and rotation stay. Forms copy when the source PDF allows it. Locked files need unlocking first.

Is there a file limit?

You can merge up to 40 PDFs at once. Very large scans work better after compressing.

Yes. Browser tools run on your device. Files are not stored on a server unless you use the API, CLI, MCP, or apps.

What happens to my file?

On Free, nothing is uploaded. The file stays in your browser and disappears when you close the tab. Pro and Studio add API, CLI, MCP, and apps, not a file locker.

Can I use this at work?

Yes. Use the site in the browser for free. For the same tools in your workspace, open Apps and start with the API, CLI, or MCP on Pro.
