Crop Video Online

Reframe horizontal footage for vertical Shorts, cut out letterboxing, or focus on the subject with preset 16:9, 9:16, 1:1, and freeform crops. See the safe area live, then export a new MP4 sized for TikTok, Instagram, YouTube, and LinkedIn.

Cropping runs in-browser with FFmpeg — your uncropped master file stays on disk unless you choose to share the export.

How to crop a video for social platforms

1

Upload

Load landscape or portrait source material.

2

Pick aspect preset

Choose 16:9, 9:16, 1:1, or drag a custom rectangle.

3

Position the frame

Center faces or products inside the crop box.

4

Export

FFmpeg crops and re-encodes to your selected dimensions.

5

Verify on phone

Open the output on mobile to confirm important content stays in frame.

Common use cases

  • Landscape to Shorts

    Turn webinar recordings into vertical clips without re-shooting.

  • Remove black bars

    Eliminate letterboxing from old downloads or screen caps.

  • Product focus

    Tighten frame on the item when the camera was too wide.

  • Talking-head social

    Keep eyes in the upper third for 9:16 Reels.

Best practices

  • Shoot 4K when possible — cropping throws away pixels; higher source resolution keeps sharpness.
  • Leave headroom for platform UI overlays (like buttons on Shorts).
  • Pair with compress when vertical exports are too large for DM limits.
  • Rotate first if the clip is sideways, then crop.
  • Trim dead air before cropping to save encode time.

Formats & compatibility

Exports MP4 (H.264). Crop dimensions depend on preset and source resolution. Extreme crops on 720p sources may look soft on large displays — prefer higher-resolution masters.
