Do I need an account to scan? No — and there’s nothing to sign into

No account exists to create. There's no registration form anywhere in the flow, no login wall before download, no “continue with Google”. Open the page, scan, save — done.

Why no accounts, structurally

Accounts exist so services can store things about you — files, history, preferences, marketing consent. ToPDF stores none of that: scans are processed on your device and saved to your storage; there's no server-side anything to attach an identity to. The account is absent because its purpose is absent. (The deeper case.)

What you might miss (and what covers it)

• Scan history / library: your file system is the library — better named, better backed up, yours.
• Cross-device sync: your existing file sync (Drive, iCloud, whatever) already does this for the PDFs you save.
• Preferences: the one setting (theme) is remembered by your browser locally.

Frequently asked questions

How do you prevent abuse without accounts?

There’s nothing to abuse server-side — no storage, no compute, no quotas. The economics of on-device tools make abuse-prevention infrastructure unnecessary.

Can I use it on a shared computer safely?

Yes — with no login there’s no session to forget to log out of. Downloaded PDFs go to that machine’s storage, so save to a USB/your cloud and clear Downloads if the machine isn’t yours.
