No. The video is read, cropped and saved by your own browser, so the file stays on your device. The page and its video engine load from our site like any web page, but your video is not sent to us or anyone else. Browsers without their own AAC audio encoder (Firefox, and Chrome or Edge on most Linux systems) may download one from dragbin.com the first time a soundtrack has to be re-encoded, for example Opus audio in a WebM going into an MP4. Only that encoder is downloaded; your video stays on your device. ### Which aspect ratios can I crop to? Free, the original ratio, 1:1, 4:5, 9:16, 16:9 and 4:3. Drag the box over a frame of the video, or type X, Y, width and height in video pixels. The box and the numbers stay in sync, and a chosen ratio stays locked while you resize. ### Why does my width or height change by one pixel? The cropped video is saved as H.264, which needs an even width and height. The tool rounds each size down to the nearest even number and shows the exact size that will be saved. ### Does cropping lower the quality? The picture inside the box keeps its full resolution, with no scaling, but the video has to be encoded again, so it is not bit-for-bit identical to the original. AAC sound is copied unchanged; other audio formats, such as the Opus sound in WebM files, are converted to AAC. ### Will a portrait phone video come out the right way up? Yes. Phones often store portrait clips sideways with a rotation flag. The tool reads that flag, shows you the upright picture, measures the crop on it, and saves the result upright. ### Which files and browsers work? MP4, MOV, MKV and WebM files your browser can decode, up to 2 GB on a computer or 500 MB on a phone or tablet. It needs WebCodecs: current Chrome, Edge and Firefox on a computer, or Safari 16.4 and later. Firefox for Android can't process video yet, and Firefox can't decode HEVC. MOV and MKV stay in their format; other files are saved as MP4.
