Join clips, trim, rotate, reframe to any aspect ratio, add text and a watermark, fix color, and export a real MP4 or WebM — all in your browser, using your device's own hardware encoder. Your video files are processed locally and are never uploaded.
This page loads consent-controlled analytics; your files and footage are never part of it.
This editor uses your browser's built-in WebCodecs engine — the same hardware-accelerated decoders and encoders the browser uses to play and record video. That means it can trim frame-accurately, join clips of different sizes, and export a genuine MP4 (H.264) or WebM (VP9) file, usually faster than real time, without your footage ever leaving your device. There are no accounts, no watermark forced onto your export, and no file-size games.
Join any number of clips in order; trim each one on a filmstrip with frame previews; rotate in 90° steps; reframe between aspect ratios (make a vertical 9:16 cut of a landscape video, or square for feeds) with fill-crop or letterbox; adjust exposure, contrast, saturation and hue per clip; set per-clip volume or mute; burn in text overlays with timing, position and outline; stamp a semi-transparent watermark image in any corner; choose your exact codec (H.264, HEVC, AV1, VP9, VP8); and export at up to 4K with quality presets. Large exports stream directly to disk in supporting browsers instead of filling memory.
HDR footage (common from recent phones) is tone-mapped through the browser canvas and exports as standard dynamic range, which can change its look. Surround audio is downmixed to stereo. Long, high-resolution exports are limited by your device's memory — a warning appears before very large jobs. Audio is re-encoded to AAC (MP4) or Opus (WebM) at 48 kHz stereo; if your browser can't encode audio, the editor tells you and offers a video-only export. Codec availability is detected on load and shown above the editor.
