Everything runs on your device. Nothing is uploaded until you save.
The whole encoder runs in your browser
Every other free online video editor works the same way: you upload your footage, their servers encode it, and you download the result. That means your unpublished video sits on someone else's disk, and it means a queue when they are busy.
This one ships a WebAssembly build of ffmpeg with the page and runs it on your own machine. Your file never leaves your computer. There is no queue, no upload wait, no file-size ceiling other than your own memory — and once the page has loaded, no network at all.
Trimming is instant. Everything else re-encodes.
Worth understanding, because it explains the speed difference you will notice. Trimming, splitting and joining copy the existing video stream without touching a pixel, so they finish in seconds regardless of length.
The moment you crop, reframe, or add a layer, every frame has to be drawn and re-compressed. That runs single-threaded on your CPU, so a six-second clip is a couple of seconds and a ten-minute one is a coffee. If you only need a shorter clip, trim first and export — you will get it back almost immediately.
Layers
- Video — drop a second clip on top, trim inside it, and move it anywhere on the timeline.
- Image — logos, end cards, stickers, held for as long as you like.
- Sound — music or voiceover, with the original audio ducked underneath automatically.
- Text — real fonts, colours, outlines and backgrounds, positioned anywhere in the frame.
Whatever sits at the top of the stack is the main layer. Move a clip up and it becomes the video everything else composites onto.
Common questions
- Is my video uploaded anywhere?
- No — and this is the unusual part. The entire encoder runs inside your browser, so your footage never leaves your computer. Most free online video editors upload your file, process it on their servers and hand you a link; this one does the work on your own CPU.
- Do I need ffmpeg installed?
- No. A WebAssembly build of ffmpeg is shipped with the page and runs in the tab. There is nothing to install and nothing to configure.
- How long does a render take?
- Trimming, splitting and joining are stream copies — a few seconds, because nothing is re-encoded. Anything that changes the picture (cropping, reframing to 9:16, layers, text) has to re-encode, and that runs at roughly real-time-and-a-bit on a modern laptop. A very long clip on an older machine will take a while; the progress bar is honest about it.
- What can I do with it?
- Trim and split, cut a section out of the middle, reframe to 9:16, 1:1 or 4:5 with a crop you control, and stack layers — extra video, images, sound and text — on top, each with its own timing. Export straight to MP4.
- Why is there no AI?
- Because it does not need any. Trimming a clip and putting text on it are solved problems that should be instant and free. Adding a model would make the tool slower, more expensive and less private for no gain.
