Frequently Asked Questions
Is converting MKV to WEBM free?
Yes, it is 100% free. We run ads to support the site, but the tool itself has no paywalls.
Is my data secure?
Absolutely. Unlike other online converters that require you to upload your confidential files to their servers, we use FFmpeg.wasm to process everything inside your browser. Your data never touches our servers.
Can I do batch conversions?
Yes! You can select multiple MKV files at once and convert them all to WEBM in a queue.
How long does it take?
It depends on your device's speed. Since it runs locally, a powerful computer will convert faster than a mobile phone. For most short clips, it's instant.
