WEBM is the format of the web: screen recorders, browser capture APIs, and many recording tools produce it by default. But step outside the browser and support gets thin - iPhones won't play it, most video editors won't import it, and many platforms reject the upload.
MP4 with H.264 plays literally everywhere. Converting your WEBM screen recording to MP4 means you can edit it, share it in chat apps, upload it anywhere, and send it to anyone without playback issues.
Our converter decodes the VP8/VP9 video and re-encodes it as H.264 using your device's hardware-accelerated encoder, so conversions are much faster than typical WASM-based tools.
The entire conversion runs inside your browser - your video is never uploaded to any server. That matters for screen recordings, which often contain sensitive information like emails, dashboards, and internal tools.
Free, unlimited, no watermark, no registration.
