Questions

Is the FLV to WebM converter free?

Yes, it is free with no sign-up and no watermark. There is no cap on how many files you can convert, and nothing to install.

Do my files get uploaded to a server?

No. The conversion runs entirely in your browser using code that loads onto your device, so the file is read, converted, and downloaded locally. It never reaches us or anyone else.

Will the conversion lose quality?

WebM uses lossy compression, so re-encoding can cost a little quality. Near the top of the quality setting the difference is hard to see, and for most uses it is not noticeable.
