Processed in your browser. Files are never uploaded.
Files stay on your device. The first run downloads the processing engine once (about 30 MB).
Drop a video file onto the converter or click to browse your device.
“Automatic” keeps the original quality whenever the codecs allow it. “Re-encode” always produces standard H.264 and AAC.
Press Convert, preview the MP4 on the page and download it.
Many MOV and MKV files already contain H.264 video. The converter detects this and rewrites only the container, which is fast and lossless.
VP8, VP9, AV1, MPEG-4 and other codecs are re-encoded to H.264 with sensible quality settings and the faststart flag for web playback.
Open MP4, MOV, WebM, MKV, AVI, M4V and 3GP files, including recordings from iPhone, OBS and screen recorders.
The converter is ffmpeg compiled to WebAssembly. It loads once, then works on your device without sending your video anywhere.
Turn MOV recordings into MP4 for Windows PCs, Android phones and web forms.
Convert MKV recordings from OBS to MP4 before editing or uploading.
Convert WebM screen captures to MP4 for slide decks and documentation tools.
Create new footage, plan your story or improve your source.
MP4, MOV, WebM, MKV, AVI, M4V and 3GP are supported, along with most other formats ffmpeg can read.
Not in Automatic mode when the video is already H.264 or HEVC: the stream is copied unchanged. When re-encoding is required, the converter uses a high-quality setting that is visually very close to the source.
Re-encoding decodes and compresses every frame on your device. A modern laptop handles a one-minute 1080p clip in roughly one to three minutes.
No. The tool runs inside your browser tab with WebAssembly. Your file is read from your device, processed in memory and offered back as a download. EveryGen never receives a copy of it.
Yes. Because the work happens on your own device, there is no processing cost for us to pass on. You do not need to sign in, nothing is added to your file and there is no daily limit.
Files up to 500 MB are accepted. Above about 200 MB the tool warns you first, because browser memory is limited and long, high-resolution videos take longer to process. A desktop browser handles large files better than a phone.
