Convert Video to MP4 Online
Convert supported video files locally to MP4 when your browser supports it, or WebM otherwise. Check the actual output format before sharing. Codec support and quality depend on your browser and source.
Convert a video to MP4
Pick a video, convert it to MP4 in your browser, then download the result. When your browser can't output MP4, it saves a WebM file instead.

A quick fix for the wrong file type
Get a file that plays everywhere
Convert supported video files locally to MP4 when your browser supports it, or WebM otherwise. Check the actual output format before sharing. Codec support and quality depend on your browser and source.
Your video stays on your device
The file is converted in your browser and never uploaded to DojoClip, so private and unreleased clips stay yours.
Fix "won't play" or "won't upload"
When a clip is rejected by an app or a player shows a black screen, converting the format is usually the fix.
Works with the files you already have
Import MP4, MOV, MKV, AVI, and WebM when your browser can decode them. Downloads are MP4, or WebM as a fallback.
Free, no sign-up, no watermark
Download the converted file with no account, no queue, and no DojoClip watermark added to your video.
Fast for everyday clips
Processing time depends on duration, resolution, codecs and your device. Larger files need more time and memory. Keep this tab open until the result is ready.
Input and Output Formats
Support depends on the file container, its codecs and your browser. Try an H.264 MP4 first; MOV and WebM support depends on their contents. A file extension alone does not guarantee compatibility.

Turn any clip into a file that just works
A video that plays fine on your phone can still be rejected by an upload form, refuse to open in an editor, or show a black screen on someone else's device. That usually comes down to the format, not the video itself. Converting the clip to MP4 - the format almost everything accepts - is the quickest way to make it play and upload where you need it.
Convert without uploading your video
This tool processes your media locally in your browser. Your source files are not uploaded to DojoClip. Keep the tab open while processing and save the result before leaving.
Shrink or trim while you're at it
If the converted file is still too big to share, reduce it with the free video compressor, cut it down with the video trimmer, or reframe it with the video cropper.
FAQ
Is the video converter free?
Yes. This tool is free, with no account or added DojoClip watermark. Processing happens on your device; browser support and available memory still limit the files you can use.
Does it always convert to MP4?
It creates an MP4 when your browser supports MP4 output. If it doesn't, the tool saves a WebM file instead, which most modern apps and browsers also accept.
Is my video uploaded to a server?
No. Your browser decodes and re-encodes the file locally, so the video never leaves your device - useful for client drafts and private footage.
Why should I convert a video to MP4?
Convert supported video files locally to MP4 when your browser supports it, or WebM otherwise. Check the actual output format before sharing. Codec support and quality depend on your browser and source.
Which browsers work best?
Chrome and Edge give the most reliable results for browser-based conversion, including MP4 output. MP4, MOV, and WebM sources are the safest inputs.
