Compress an MP4 — without uploading it
Fit under a size limit. No upload, no watermark, no cap.
Fit under a size limit. No upload, no watermark, no cap.
An MP4 is usually the largest file anyone routinely needs to shrink, and upload-based compressors handle that badly: you wait for the upload, wait in a queue, wait for the download, and frequently find a size cap or a watermark at the end of it.
ClipFit encodes in the browser using WebCodecs, the same engine your browser already uses to play video. There is no upload, so a large file costs local processing time and nothing else.
The single biggest reduction available is usually removing the parts you do not need. Thirty seconds of a three-minute clip is a 90% saving before any quality is touched — always trim first, then compress what is left.
Cropping helps too, particularly if the footage has letterboxing eating pixels you are paying to encode.
No fixed cap. The practical ceiling is your device's memory, since the video is processed locally.
No. No watermark and no sign-up, including on the output.
ClipFit needs WebCodecs, so an up-to-date Chrome, Edge, Firefox or Safari.
