Features
Stitch Any Clips Into One
Combine multiple video files into a single seamless MP4. Reorder, remove, and merge — all without leaving the browser.
Multi-File Upload
Pick or drop several videos at once. The list grows as you add more — perfect for highlight reels and chapter compilations.
Reorder & Remove
Move any clip up or down with arrow controls, or remove the ones you do not need before merging.
Universal MP4 Output
Mixed sources (MP4, MOV, WebM, AVI, MKV) are normalized then concatenated into one universally playable MP4.
Smart Re-Encoding
Different cameras, codecs, and frame rates? No problem. Each clip is normalized to a common pipeline so the final concat is glitch-free.
H.264 Veryfast Preset
Each input is re-encoded to H.264 with a high-quality CRF — visually indistinguishable from the source.
Unified Audio Pipeline
All audio tracks are converted to AAC at 44.1 kHz so volume, sample rate, and codec match across every clip.
Faststart MP4
Output MP4 has the moov atom up front so it starts playing instantly when shared online.
100% Private & Free
Your footage never leaves your device — everything runs in the browser tab using WebAssembly.
Zero Server Upload
Files are read, normalized, concatenated, and written back entirely on your own machine.
No Watermark
The exported video is clean — no logo, no stamp, no branding overlay.
Works Everywhere
Any modern browser — desktop or mobile. Chrome, Firefox, Safari, Edge.
