Frequently asked questions
Are uploaded images sent to Tervix?
No. Decoding, resizing and export happen with browser APIs on your device.
Does Tervix connect to or publish on my accounts?
No. It requests no credentials, accesses no profiles and publishes nothing automatically.
Should I review the result?
Yes. Review text, links, dimensions and current platform rules before using it.
