Video tools without the upload step

Trim, convert, compress, and join video in your browser. Unlike conventional online video sites, there is no upload: the frames are decoded and re-encoded on your own device, so the footage never leaves your machine.

Video is usually the most personal — and the largest — thing people push through an online converter. Uploading a multi-gigabyte file to a server is slow, capped by free-tier quotas, and leaves a copy of your footage on someone else’s infrastructure. Processing it locally removes all three problems at once: no waiting on an upload, no server quota, no copy to worry about. You can watch the Network tab while a tool runs to confirm nothing is transmitted.

Ads and aggregate analytics stay outside the video-processing path and never receive frames, audio tracks, file names or output buffers. The tools are also free, with no watermark or signup.

Questions

Is my video uploaded to a server?

No. The video is decoded, processed, and re-encoded in your browser using WebAssembly and WebCodecs. Its contents are never transmitted — you can verify this in your browser’s Network tab while a tool runs.

Is there a size or length limit?

No server quota — the practical limit is your own device’s memory and speed. Long, high-resolution videos take longer to process locally than short clips, but nothing is capped or paywalled.

Is there a watermark on the output?

No. The output is your video, unmarked, with no signup required.

Why are browser video tools faster to start with?

There is no upload step. With a server-side tool, a large video spends minutes uploading before processing even begins; here, processing starts immediately from the file on your disk.
