About formats

MP4

MP4 (MPEG-4 Part 14) is a digital multimedia container format standardized by the Moving Picture Experts Group (MPEG). It stores video, audio, subtitles, and still images in a single file and is the most widely used format for streaming and sharing video across the web, mobile devices, and living-room hardware. MP4 offers an excellent balance between compression efficiency and quality, typically using the H.264 or H.265 (HEVC) video codec together with AAC audio. Its near-universal support makes it the default choice for social media platforms, browsers, phones, and modern TVs.

Frequently Asked Questions

Is converting MP4 to WMV free?

Yes. This MP4 → WMV converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert MP4 to WMV?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my MP4 files uploaded to a server?

No. Files never leave your device. The entire MP4 → WMV conversion runs locally in your browser, so your data stays private.

Can I convert multiple MP4 files at once?

Yes — batch conversion is supported. Add as many MP4 files as you like and convert them to WMV in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting MP4 to WMV reduce the quality?

Because both formats use lossy compression, the WMV output will not bring back any quality that has already been lost in your MP4 file. Avoid repeated re-encoding to keep the best quality.

Does WMV support transparency?

No — WMV has no alpha channel. Transparent areas of your MP4 file will be filled with a solid background colour in the converted file.

How will the file size change after converting MP4 to WMV?

Both formats use comparable compression, so the WMV output will be similar in size to your MP4 file — typically within 10–20% of each other.
