Video without the upload

Compress and edit video in your browser.

Trim, resize, extract the audio, or make a GIF — no watermark, no length cap, and nothing uploaded to a server.

GhostVideo compresses and edits video entirely in your browser — no upload, no watermark, no signup. Compress a clip to a smaller size, resize or rotate it, trim it, remove the audio track, extract the MP3, or turn it into a GIF. It runs on ffmpeg compiled to WebAssembly, so even large recordings are processed on your own device and never sent to a server — which is why there's no upload wait and no file-length cap.

How it works

  1. 1

    Add your video

    Drop an MP4, MOV, WebM or other video. It loads locally — no upload progress bar because nothing is uploading.

  2. 2

    Compress, trim, or convert

    Compress to shrink the file, trim to a clip, remove audio, extract the MP3, or make a GIF.

  3. 3

    Download the result

    Save the finished video, audio, or GIF straight from the browser.

Questions, answered

Can I compress a video in the browser without a watermark?

Yes. GhostVideo compresses locally with ffmpeg (WebAssembly) and never adds a watermark. Pick a quality level and download — the file is never uploaded.

Isn't in-browser video processing slow?

The first run downloads the ffmpeg engine (a few seconds), then processing runs at native-ish speed on your device. For short-to-medium clips it's comparable to a desktop app, with the upside that nothing uploads.

How do I turn a video into a GIF?

Add the video, use Trim to pick the segment, then the Make GIF operation. Everything runs locally.

Can I extract the MP3 audio from a video?

Yes. Use Extract MP3 to pull just the audio track out of a video file in your browser.

How do I remove the audio from a video?

Use the Remove Audio operation to strip the soundtrack and export a silent video.

Everything runs in your browser. Your files are never uploaded — for the single-file tools there's no upload endpoint to send them to.
