Frequently Asked Questions

Is converting MPG to WEBM free?

Yes. This MPG → WEBM 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 MPG to WEBM?

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 MPG files uploaded to a server?

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

Can I convert multiple MPG files at once?

Yes — batch conversion is supported. Add as many MPG files as you like and convert them to WEBM 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 MPG to WEBM reduce the quality?

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

Does WEBM support transparency?

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

How will the file size change after converting MPG to WEBM?

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