Is it safe to convert WMV to MP4 here?

Yes — free with no watermark. Signed-out visitors can convert 25 files a day, and a free account raises that to 250.

MP4 is a lossy format, but our defaults are tuned to be visually indistinguishable for most files. You can raise the quality under Options.

Can I convert multiple WMV files at once?

Yes. Add up to 5 files at a time without an account, 10 with a free account and up to 500 on paid plans, then download them individually or as a single ZIP.

Can I convert MP4 back to WMV?

Yes — use our MP4 to WMV converter. Note that converting back and forth between formats can't recover detail lost to lossy compression.
