Every platform has different dimensions. Crop once, post everywhere -- without awkward cuts.
Each social platform displays images at specific aspect ratios. If your image does not match, the platform crops it automatically -- often cutting off important content. Manual cropping gives you control over which part of the image viewers see.
| Platform | Post type | Size | Ratio | Tool |
|---|---|---|---|---|
| Square post | 1080 x 1080 | 1:1 | Resize | |
| Portrait post | 1080 x 1350 | 4:5 | Resize | |

If you need the same image for multiple platforms, start with the largest dimensions and crop down. A 1080x1080 Instagram square can be cropped from a 1080x1350 portrait, but not the other way around without stretching.
Different platforms crop differently. Keeping your main subject in the center of the frame ensures it is visible in every crop. Leave extra space around the edges (called safe area) for platform-specific cropping.
Instagram rounds profile pictures. YouTube overlays video duration in the bottom-right corner of thumbnails. Facebook mobile crops cover photos differently than desktop. Keep critical content away from corners and edges.
Our Image Cropper supports custom aspect ratios and exact pixel dimensions. Upload your image, select the crop area, and download the result. Everything runs in your browser -- your images never leave your device.
Not ideally. Each platform has different dimensions and aspect ratios. A single image will be auto-cropped differently on each platform, often cutting off important content. Create platform-specific crops for best results.
There is no single best ratio. Instagram favors 4:5 portrait for maximum screen real estate. YouTube and X use 16:9 landscape. TikTok and Stories use 9:16 vertical. Choose based on your target platform.
Edit first, crop last. This gives you the most flexibility. If you crop first and later realize you need more background space, you cannot get it back without starting over.
