Frequently Asked Questions
Yes — completely free, no limits, no watermarks, and no account required. Convertlo runs entirely in your browser using the open-source qpdf engine compiled to WebAssembly.
If the PDF has an open password (it prompts you before it will open), yes — enter that password so the tool can decrypt it. If the PDF opens fine but blocks copying or printing (owner restrictions only), you can leave the password blank and just remove those restrictions.
No. Everything happens locally in your browser. Your PDF and the password you type never leave your device, which is essential for confidential documents.
No. This tool removes a password you already have the right to use — it does not guess, brute-force, or bypass unknown passwords. That is by design and keeps it a legitimate tool.
Some PDFs are saved with owner-permission flags that restrict printing, copying text, or editing, even though the file opens without a password. If you have the right to use the document, this tool can remove those flags.
No. Unlocking only removes the encryption and permission flags. All pages, text, images, and formatting are preserved exactly as they were.
