Frequently asked questions
Are my files uploaded to a server?
No. All processing happens in your browser using open-source libraries, so your files stay on your device.
Is ToolNest free to use?
Yes, every tool is free with no account, no watermarks, and no page limits.
Can I merge or split large PDF files?
Yes. Large files are handled in the browser; very large documents just take a little longer depending on your device.
Does the PDF password remover crack passwords?
No. You must already know the password. The tool only creates an unprotected copy of a PDF you can open.
