- Export locally, then preview and download the result before leaving. Cancel or clear to release temporary media.
What this tool does
Select playable video clips and set start/end seconds. Merge joins up to five clips in the displayed order. The Video Editor adds center-crop aspect presets, output-size presets, rotation, playback speed, audio gain/mute and a text overlay. Canvas and Web Audio feed the browser recorder. Output is re-encoded in real time and downloaded with the actual supported WebM or MP4 extension. This is a bounded single-sequence editor, not a multitrack timeline.
Supported files, limits & important details
Browser-local processing; no uploads or autosave. Up to five files, 20 MB each and 60 MB combined; up to 120 seconds of source media combined. Browser codec support determines which inputs decode. Video: maximum 1280-pixel output side and 30 fps target, real-time export, not frame-accurate/lossless. Keep the page visible; hiding it cancels export. Output container is negotiated, not a guaranteed MP4. Audio exports PCM WAV only; MP3/AAC encoding is not included. Encrypted/DRM, subtitles, multiple audio tracks, transitions and background exports are not supported. Large decoded media can still exceed device resources. Physical mobile/Safari support requires separate acceptance.
Input limits are enforced before processing. Clear removes your input and result from this page. This tool does not store your input between visits.
