Frequently Asked Questions

Why convert WebM to MP4?
MP4 is the most reliable format for sharing videos on social media and playing them on TVs, phones, and consoles across Australia. Unlike WebM, MP4 works everywhere without 'format not supported' errors.
Will converting WebM to MP4 increase file size?
MP4 files can be a bit larger than WebM at the same quality level because of different compression methods. However, the improved compatibility usually makes the small size increase worth it.
Does WebM to MP4 conversion lose quality?
Our tool uses efficient H.264 encoding to keep quality loss to a minimum. The difference is virtually undetectable, so your clips look just as good as the original.
What is the maximum file size?
You can convert WebM videos up to 50MB. If your file is larger than 50MB, we suggest trimming it or lowering the resolution before converting.
Are my videos safe and private?
Definitely! The conversion happens locally in your browser on your device in Sydney, Melbourne, or wherever you are. Your videos are never uploaded to our servers, ensuring total privacy.
