Why convert WMV to MP4?
Both WMV and MP4 use lossy compression, so the conversion mainly changes compatibility, not quality. The main reason to convert WMV to MP4 is compatibility: MP4 plays back smoothly in browsers and on mobile without a codec pack, while WMV doesn't always. If you're sharing a file with someone else, sending it to a tool that expects a specific format, or archiving it for the long term, MP4 is usually the safer target.

Frequently asked questions
Is converting WMV to MP4 free?
Yes — the first 50 conversions every month are free on any plan, including WMV to MP4.
Will I lose quality converting WMV to MP4?
MP4 is the default web and mobile video container. We use the highest-quality encoder settings by default so visual or data loss is minimized.
Do you keep a copy of my file?
No, not by default. You choose a retention window at upload — immediate, 1 hour, 24 hours or 7 days — and the file is permanently deleted after that.
What is WMV?
Windows Media video format.
Will my converted file have a watermark?
On the Free plan, MP4 output includes a small "Converted with Convyx" mark. Pro ($9/mo) removes it, along with the 25 MB file size cap.
What happens if a conversion fails?
You get a clear error message and the job is marked failed in your history — we never silently drop a file. Retry is one click, and nothing is charged against your quota for a failed job.
