Key takeaway
Cropping reframes an image to a target aspect ratio so faces and products stay in frame on each channel.
A perfect square crop for one app may chop heads on another — plan safe zones.
What it means
Aspect ratio examples: 1:1, 4:5, 16:9, 9:16.
Composition matters more than raw resolution once size is adequate.
Cropping is destructive to the exported frame — keep masters.
When you would use it
Social posts, ads, avatars, YouTube thumbs, product tiles.
How to use the tool
Use the matching TCB Tools page and work top to bottom:
- Open Image Cropper.
- Load image.
- Choose ratio/presets.
- Position the subject.
- Export per channel.
No account is required. Results update as you type.
How the process works + example
Example: shoot wider than 1:1 so you can crop both 1:1 feed and 9:16 story from one master.
Keep critical text inside central safe areas.
How to read the result
Zoomed previews can mislead — check at display size.
Different channels trim previews differently.
Local processing limits still apply.
Common mistakes
- Cropping from an already tiny export. Start large.
- Text near edges. Leave padding.
- One crop for all platforms. Make variants.
- No master kept. Archive originals.
