Common questions
Do files leave my computer?
Files, pasted text and generated results are processed in this browser. They are not uploaded to a conversion server. Engine downloads can require internet access; large operations depend on the memory and CPU available on this device.
Can I convert files without internet access?
The website and required engine assets must load first. Processing runs on this device; a fresh visit or an uncached engine still requires internet access.
How long can I download completed results?
