Change Video Aspect Ratio Online

Free, simple to use online tool for changing the aspect ratio of your video files. You can use it to stretch the video to fill a specific aspect ratio (like 16:9, 4:3, 1:1 for Instagram, 9:16 for TikTok/Shorts) without cropping, or crop the video to remove black bars or focus on a specific area.

This tool supports various video formats including MP4, WebM, AVI, MPEG, FLV, MOV, 3GP and others. You can also choose the output format and encoding for the processed video.

Features

  • Change Aspect Ratio: Force the video to fit a new aspect ratio. You can choose to either stretch the video to fill the screen (may distort the image) or pad it (add black bars, letterbox/pillarbox) to fit perfectly without distortion.
  • Crop Video: Automatically detect and remove black bars (letterboxing/pillarboxing) or crop the video to a standard aspect ratio like 16:9, 4:3, square (1:1), or vertical (9:16).
  • Output Options: Save the video in its original format (if possible), or convert it to MP4 (H.264/AAC) or WebM (VP8/Vorbis) for better compatibility.
  • No Watermark: The tool is completely free and does not add any watermarks to your videos.
