GOOD TO KNOW

Frequently asked
questions

Answers to the most common questions about using SupUser.

Do I need to create an account?

No. The tools listed here can be used without a SupUser account.

Are my selected PDFs uploaded to your server?

The tools process the selected PDF and image content locally in your browser. Your browser may load JavaScript libraries from third-party content delivery networks, but the tools do not intentionally transmit selected document contents to our servers.

Is every PDF feature guaranteed to be preserved?

No. Certain PDFs have encryption, interactive forms, signatures, annotations, or unusual structures. Keep your original and verify every downloaded result.

Does the site work on mobile?

Yes, the layout is responsive. Very large PDFs may be more comfortable to process on a device with additional memory.
