Need to remove black bars, change aspect ratio, or focus on a specific area of your video? The MyPDF Video Crop tool lets you crop the video frame to any dimensions or aspect ratio.
How to Crop a Video
- Upload your video file (MP4, MOV, AVI, WebM).
- Drag the crop box or select a preset aspect ratio (16:9, 9:16, 1:1, 4:5).
- Download the cropped video instantly.
Common Crop Ratios
| Ratio | Dimensions | Platform |
|---|---|---|
| 16:9 | 1920x1080 | YouTube, desktop |
| 9:16 | 1080x1920 | TikTok, Reels, Shorts |
| 1:1 | 1080x1080 | Instagram feed |
| 4:5 | 1080x1350 | Instagram portrait |
| 4:3 | 1440x1080 | Classic TV format |
Practical Tips
- Crop to 9:16 to repurpose horizontal YouTube videos for TikTok and Instagram Reels.
- Remove letterbox bars (black bars top/bottom) from old videos by cropping to the actual content area.
- Center the crop on your subject — the tool lets you drag the crop area to any position within the frame.
Is cropping the same as trimming?
No. Cropping changes the frame dimensions (spatial). Trimming changes the duration (temporal). Use Video Trim to cut start/end times.
Will cropping reduce video quality?
Cropping removes pixels outside the crop area but does not degrade the remaining pixels. Quality stays the same within the cropped region.
