Video Crop
Crop a video: play to the frame you want, capture it, then drag to select the crop area
Crop a Video to an Exact Region or Aspect Ratio
Because a video file doesn't have a single frame you can click on ahead of time, this tool has you play the video to whatever moment you want, capture that exact frame to a canvas as a reference image, then drag a selection box over it. Once you confirm the crop rectangle, those x/y/width/height coordinates are passed to ffmpeg.wasm's crop filter and applied to every single frame of the video, re-encoding the picture with libx264 while copying the audio track through untouched.
The two-step play-then-capture flow exists because auto-grabbing a frame the instant a video loads is unreliable across browsers, especially on mobile, so you explicitly choose the reference frame and confirm the capture before drawing a crop box. Aspect ratio presets (16:9, 9:16, 1:1, 4:3) are built into the selector for cropping straight to a target platform's shape, or you can drag freely for an arbitrary rectangle.

Key Features
- →Use 9:16 for TikTok/Reels, 16:9 for YouTube, 1:1 for Instagram.
- →Pause the video on the most representative frame before capturing.
- →The crop area applies to ALL frames of the video, not just the reference frame.
- →If the captured frame doesn't match what you expected, click Recapture rather than trying to fix the selection against a stale frame.
- →The output resolution equals your selection's exact pixel dimensions, so a tighter crop produces a smaller output video.
- →Audio is copied without re-encoding, so cropping the picture doesn't touch audio quality or sync.
Frequently Asked Questions
How do I crop a video online for free?
Upload to ezyimg's Video Crop, play to any frame, click Capture, drag to select the crop area, then click Crop. Works on all devices including mobile.
Can I crop a video to 9:16 for TikTok?
Yes. Capture any frame, select the 9:16 aspect ratio preset, drag to position, click Crop.
Why do I have to click a button to capture a frame instead of it happening automatically?
Some browsers, especially on mobile, don't reliably expose a video frame to canvas the instant a file loads. A manual capture button guarantees a frame is actually ready before you try to crop against it.
Does cropping re-compress the whole video or just the cropped area?
The whole video is re-encoded with libx264 at the new dimensions, since every frame needs the same crop applied. The audio track is copied as-is, without re-encoding.
