FAQ

Do my files ever leave my device?

No. All processing happens locally in your browser. If a feature ever needs a server in the future, we will label it clearly.

Does it work offline?

Yes. Add it to your Home Screen or keep the tab open; most tools continue to work without a network connection.

Is there a file size limit?

Limits are primarily determined by your device memory. We optimize operations to handle large PDFs gracefully.

Is it free?

Yes. Core tools are free to use. Advanced features may arrive later, but the basics will stay free.
