Why convert WEBM to MP4?
- Editing apps like Premiere, Final Cut and DaVinci Resolve handle MP4 far better than WEBM.
- PowerPoint, Keynote and Google Slides embed MP4 natively; WEBM often shows a black box.
- Most phones and TVs made before 2020 can't play WEBM at all.
About WEBM
WEBM is Google's open web video format (VP8/VP9/AV1 video with Vorbis or Opus audio). It's the default for many screen recorders, Discord clips and HTML5 video — but it won't play in most editors or on older devices.
About MP4
MP4 with H.264 is the one format that plays everywhere: editing apps, phones, TVs, PowerPoint, you name it. Converting WEBM to MP4 makes your recording editable and shareable.
WEBM to MP4 — FAQ
How do I convert WEBM to MP4 for free?+
Upload the WEBM to VidFlip, choose MP4 as the output, and download. It runs in your browser — no install, no account. Launching soon; join the waitlist above to get notified.
Why did my screen recording save as WEBM?+
Many free screen recorders (OBS in default settings, browser-based recorders, Discord clips) save as WEBM because it's royalty-free and streams well on the web. Converting to MP4 afterward is the standard workflow before editing.
Will converting WEBM to MP4 lose quality?+
VP9 and AV1 video usually has to be re-encoded to H.264 for MP4, which is a lossy step. At a sensible bitrate (VidFlip defaults to high quality) the loss is not visible for screen recordings and gameplay footage.
Can I convert WEBM to MP4 on my phone?+
Yes — VidFlip works in mobile browsers on both iPhone and Android. Open the page, pick your WEBM file from Files or Downloads, and save the MP4 back to your device.
