Frequently Asked Questions

Is this tool really free?

Yes — 100% free with no signup, no subscription and no limits. All processing happens in your browser.

Are my files stored anywhere?

Never. Processing happens entirely in your browser. Files never leave your device.

Is it secure?

Yes. PDF.js (Mozilla's open-source library) runs locally and ignores scripts embedded in PDFs.

Does it work on mobile?

Yes — iOS Safari 14+, Chrome and Firefox on Android fully supported.

Will there be a watermark?

No. CuroPDF never adds watermarks to your output files.
