What is Video Cropper?

Crop your videos to any dimensions or aspect ratio. Upload a video, select a crop region visually or choose a preset ratio (16:9, 9:16, 1:1, 4:3), preview the result, and export the cropped video.

Input accepts MP4, WebM, and MOV up to 500 MB. The eight built-in presets cover 16:9, 9:16, 1:1, 4:3, 4:5, 3:2, 2:1, and the 1.618:1 golden ratio, plus a free-form drag mode for any custom rectangle. An optional trim range lets you cut the start and end so a single export both reframes and shortens the clip, and a quality slider trades file size against sharpness before you export. The crop runs through a free video engine right on this page — audio is preserved, video is re-encoded as H.264 MP4. Processing time depends on duration and your device's CPU.

How to use

  1. Upload a video file. The original dimensions and duration are displayed automatically.
  2. Pick a preset aspect ratio or drag the crop handles to set a custom region. Use the frame scrubber to land on the exact moment, and optionally set a start and end time to trim the clip at the same time.
  3. Click export to process the video and download the cropped result as MP4.

When to use

  • Reframing a landscape 16:9 video as 9:16 vertical for Reels, Shorts, or TikTok.
  • Cropping a square 1:1 clip from a wide-format video for an Instagram feed post.
  • Removing letterboxing or unwanted edges from screen recordings or webcam captures.

Result

Say you shot a 16:9 landscape video but need a 9:16 vertical clip for Instagram Reels. Upload it, pick the 9:16 preset, drag the crop window to keep your subject centered, and export the vertical version.

FAQ

Will cropping reduce the video quality?
Cropping itself doesn't degrade quality — you're keeping a subset of pixels. The re-encode uses H.264 at the quality you set with the export slider, so there's a small generation loss similar to any video editor; nudge the slider toward best quality to keep it minimal. For most clips it's not visible.
Why does processing take so long for a short video?
All encoding runs locally on your CPU, not on a server. A 60-second 1080p clip usually takes 30–90 seconds depending on your hardware. Close other tabs while it runs — the encoder benefits from full CPU access.
Is the audio preserved when I crop?
Yes. The audio track is copied through unchanged, so there's no quality loss on the sound. Only the video stream is re-encoded for the new dimensions.
What's the maximum file size I can upload?
500 MB. Above that the engine on this page runs out of memory on most devices. If your clip is larger, use the built-in trim range to keep only the part you need, or lower the bitrate before cropping.
Can I crop without re-encoding to keep the file identical?
Lossless crop requires the original video's keyframes to align with the crop edges, which almost never happens. This tool re-encodes for clean output. For lossless trimming, look for tools using the `-c copy` flag in FFmpeg.
