Frequently Asked Questions

Is converting MTS to WEBM free?

Yes. This MTS → 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 MTS 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 MTS files uploaded to a server?

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

Can I convert multiple MTS files at once?

Yes — batch conversion is supported. Add as many MTS 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 MTS 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 MTS file. Avoid repeated re-encoding to keep the best quality.

Does WEBM support transparency?

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

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

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