How it works

Upload, choose settings, process locally, download

ClearPDF validates file type, shows the processing mode, prepares a preview/workspace, and exposes result actions for download, continuing to another tool, or saving later when accounts are available.

Help

Common questions

Does ClearPDF upload my file for this tool?

Phase 1 local tools run in your browser. The file stays on your device unless a page explicitly says cloud, AI, or API processing.

Do I need an account?

No account is required for Phase 1 local tools. Paid accounts are planned for cloud, OCR, AI, batch, team, and API usage.

Will there be a watermark?

ClearPDF local tools are designed without watermark or pay-to-download traps.

What if my PDF is password protected?

Encrypted or password-protected files may need the original password. ClearPDF should show an actionable error instead of processing silently.

Can I use this on mobile?

Yes. Upload, settings, progress, download, and continue actions are designed for mobile and desktop.
