Crop screen recordings for demos and social video
Use 16:9 for a wide tutorial, 9:16 for a vertical clip, 1:1 for a square post, or 4:5 for a portrait post. Reduce the crop size to cut out desktop clutter. Check the full clip before export so the crop does not cut off text or cursor movements.
Need exact dimensions? Use the aspect ratio calculator. After cropping, use the video compressor for a smaller file or the video to GIF converter for a short demo.

Video cropper FAQ
How do I crop a video online?
Choose a video, select an aspect ratio, and adjust the crop size and position. The preview updates instantly. Select Export cropped MP4, then download the result. Export time depends on the video length and your device.
Is this video cropper free with no watermark?
Yes. The tool is free, adds no watermark, and needs no account or email address. Your video is processed on your device and is not uploaded.
Can I crop a screen recording on a Mac or phone?
Yes, if your browser supports the video's codec and H.264 encoding through WebCodecs. Choose your recording and use the crop controls to remove desktop edges or focus on an app window. If export fails, try a current Chrome, Edge, or Safari browser with an H.264 MP4 file.
Which video formats and file sizes can I use?
Choose an MP4, MOV, or WebM video up to 600 MB. Codec support depends on your browser. The result is an H.264 MP4. Short clips work best on phones because export uses your device's memory and processing power.
Does cropping reduce video quality or remove audio?
Cropping removes pixels outside the selected area. Export re-encodes the picture, so some quality loss is possible. This tool does not upscale the crop and keeps supported audio. It reports an export error if it cannot preserve an audio track.
What is the difference between cropping and trimming?
Cropping changes the visible area of each frame. Trimming removes time from the start or end of a clip. This tool crops the picture and keeps the full video duration.
