Frequently Asked Questions

Are these PDF tools really free?

Yes. All PDF tools are completely free with no sign-up required. There are no hidden fees, usage limits, or premium tiers.

Is my PDF data safe?

Your PDF is processed on your device and never stored on our servers. The one exception is the PDF Translator, which sends the extracted text to a translation service and discloses this on its page.

What's the maximum file size?

Processing is limited only by your browser's memory. Most files up to 100MB work smoothly. For very large files, try splitting first.
