What cropping a video actually does
Cropping cuts the edges of the frame. It does not cut the ends of the timeline.
The length of your video stays the same. What changes is what sits inside the picture. Three similar jobs get mixed up, so here is the split:
- Cropping: cuts the edges of the frame to change what is visible.
- Trimming: cuts the start or end of the timeline. Use the free video trimmer or read the trim how-to.
- Reframing: changes the shape of the video without losing the subject. Use the video reframer.
Which crop ratio should you pick?
The most common reason to crop is to turn a horizontal video into a vertical one. It fits TikTok, Reels or Shorts without black bars.
| Preset | Shape | Typical use |
|---|---|---|
| 9:16 | Vertical | TikTok, Reels and Shorts |
| 1:1 | Square | |
| 4:5 | Portrait | Social feeds that favor taller frames |
| 16:9 | Landscape | Standard widescreen video |
Not sure whether to crop, fit or reframe? This guide covers how to convert a horizontal video to vertical without cutting anyone off.
Why many free video croppers aren't really free
Plenty of "free" online croppers stamp a watermark across the export. Others make you sign up before you can download. You only find out after you have done the work.
Vidocu's cropper is free and exports without a watermark. It works on any device with no install.

When a crop will cut off something important
A straight crop is blunt. If you crop a wide shot to 9:16, anything outside the box is gone. That can chop off a person or a key element.
Use the reframer instead. It keeps the whole subject in view while switching aspect ratios.
- Use the cropper when you know exactly which part of the frame you want.
- Use the reframer when the subject must stay in view.
Crop, then add subtitles in the same workflow
A vertical video often plays with the sound off. Once you have cropped for TikTok, Reels or Shorts, add captions in the same Vidocu workflow.
The AI subtitles generator supports 90+ languages with word-level captions. You can also add voiceover and step-by-step docs without moving to another tool.
Create once. Use it everywhere.
