Frequently asked questions

Is there a file size limit?

Limits depend on the tool and your browser’s available memory. Large files usually work; if you run into constraints, try processing in parts or using a device with more memory.

Can I use it on mobile?

Yes. The site is mobile-friendly. For large PDFs, use a stable connection and ensure your device has sufficient storage.

Are my files uploaded?

No. Processing happens locally and your documents never leave your device. Anonymous analytics runs only if you opt in.

Is it free?

Core features are free. If advanced features are added in the future, we’ll announce details clearly on the site.
