Do my PDF bytes or password go to DevToolsAtlas servers?

No. The QPDF module is downloaded by the browser, but your selected PDF bytes and password are processed in browser memory and are not uploaded by this tool.

Can I unlock any PDF?

Only when you have the correct password or authorization to remove restrictions. DevToolsAtlas does not bypass unknown passwords.
