How to Resize Images for Social Media Without Bad Crops
Prepare social images using aspect ratio, safe composition, export dimensions and compression without relying on quickly outdated platform lists.
Aspect ratio comes before pixel count
A 1080-pixel image can still crop badly if its shape does not match the placement. Feed posts, stories, banners and profile images use different containers, and interfaces may overlay buttons or crop previews differently.
| Placement shape | Common ratio | Composition concern |
|---|---|---|
| Square | 1:1 | Keep subject away from circular profile crops |
| Portrait feed | 4:5 | Protect top and bottom text |
| Vertical story/reel cover | 9:16 | Allow space for interface overlays |
| Landscape | 16:9 | Check mobile centre crop |
These ratios are compositional starting points, not a promise about every platform placement.
A durable workflow
- Check the platform’s current composer or official help for the exact placement.
- Duplicate the master.
- Use the cropper to set the required ratio.
- Position faces, text and logos inside a generous safe area.
- Use the resizer for the requested pixel dimensions.
- Export a JPG/WebP photo or PNG graphic and inspect the upload preview.
Build variants from one master
Do not repeatedly crop an already cropped derivative. Return to the uncropped master for square, portrait and vertical versions. A subject-aware composition will usually outperform a single automatic centre crop across every placement.
Common mistakes
- Using one image for every placement.
- Putting text against the extreme edges.
- Stretching width and height instead of cropping.
- Copying an old dimension chart without checking the current publisher.
- Exporting screenshots or text as heavily compressed JPG.
Frequently asked questions
Why does a platform crop my correctly sized image?
The display container, preview, device or placement may use another ratio. Check the live preview and keep key content inside a safe area.
Should I use PNG or JPG?
Use JPG for photographs and PNG for sharp text or graphics when the platform accepts it.
