Video tools in your browser: compress, trim, convert to MP4

27 free video tools that run entirely in your browser — nothing is uploaded, so there is no queue. Compress a video to a target size, trim, crop, resize and rotate, convert MOV, WebM, AVI and MKV to MP4, turn clips into GIFs, and export for WhatsApp, Instagram, TikTok or YouTube. No account; each page states its file limit (200 or 300 MB).

 

Edit video

Trim VideoKeep only the part of a video you need. Pick the start and the end, and the cut lands exactly on the frame you chose.Crop VideoCut a video down to the part of the frame that matters. Drag the box over the picture, keep the sound, upload nothing.Resize VideoChange a video's resolution to 1080p, 720p or a size of your own. Proportions are kept, and nothing is uploaded anywhere.Rotate VideoTurn a video 90, 180 or 270 degrees, or mirror it. The fast mode rewrites the orientation without touching a single frame.Change Aspect RatioFit a video into 9:16, 1:1, 4:5, 16:9 and the other shapes platforms ask for, with blurred sides, a colour, or a centre cut.Merge VideoJoin two or more videos into one file in your browser. Matching clips are joined without re-encoding, so quality stays identical and it takes seconds.
