- How do I crop a video online?
- Upload the video, set Width × Height for the region you want to keep, set X / Y Offset for where the region starts, click Process. The video cropper runs in your browser via FFmpeg WebAssembly and finishes in seconds for short clips, minutes for long ones.
- How is this video cropper different from Clideo or Online-Convert?
- Speed and privacy. Clideo / Online-Convert upload your video to their server, queue it, re-encode, and send it back — slow on long videos and your file briefly lives on their disk. This cropper runs locally in your browser; nothing leaves your device and there's no queue. Free with no watermark or sign-up cap.
- How do I remove black bars from a video?
- Measure the visible content area (you can use the preview to eyeball it), then set Width × Height to the content size and X / Y Offset to skip the bars. Example: a 1920×1080 video with letterbox bars has content at 1920×800 starting at Y=140 — those four numbers crop the bars out cleanly.
- How do I crop a video to square for Instagram?
- For a 1920×1080 source, set Width=1080, Height=1080, X=420, Y=0 to extract a 1080×1080 square from the center. For TikTok / Reels vertical (9:16), use Width=1080, Height=1920 on a tall enough source (or pair with our video resizer after cropping).
- Does the cropper preserve audio?
- Yes — the audio track passes through unchanged. Only the video stream is re-encoded to the new dimensions.
- Can I crop an image instead of a video?
- Yes — drop a JPG, PNG, or WebP onto the same cropper and it'll crop the image with identical pixel-precise control. Output is a clean PNG or your chosen image format.
- What happens if I set the crop area larger than the video?
- FFmpeg clamps it: anything beyond the video boundary gets ignored, and you end up with the largest valid sub-region. To avoid this, keep Width + X Offset within the source width, and Height + Y Offset within the source height.
- How many pixels are the black bars on a letterboxed 1080p video?
- For 2.39:1 cinema content in a 1920x1080 frame, about 138 px top and bottom. Set Width 1920, Height 804, X 0, Y 138 to remove them. For 1.85:1 content the bars are far thinner, around 21 px each.
- Can I crop and trim a video at the same time?
- Not in one pass - crop sets the region, it does not change duration. Crop here, then cut the length with Cut Video. Trimming first is faster, because the crop then runs over fewer frames.
