FAQ

Are my files really not uploaded?

Yes. This site only serves static web pages. Your browser reads and converts the file in memory, then saves the result to your computer. You can check the Network tab in your browser's developer tools to confirm that no file is sent.

Does it work on a phone?

The image and subtitle tools work well on phones. The video tools also work, but phones have less memory, so long videos can fail. Use a computer for long videos.

Is there a file size limit?

There is no set limit. The browser has a memory limit, though. Videos up to about 1 to 2 GB work reliably.

Can I download YouTube or Instagram videos?

No. This site converts files you already have. It cannot download videos from other sites.
