READY-TO-USE IMAGE TOOL
9:16 aspect ratio crop tool.
9:16 aspect ratio uses a 1080 × 1920 pixel frame (9:16). The calculator and local image crop below are already set to that shape, so you can enter dimensions or choose an image immediately.
This is an exact mathematical ratio, not a platform upload requirement. Your image stays in this browser.
Find the ratio
Enter your pixel dimensions. Whole-number dimensions reduce to an exact ratio.
Match a ratio
Set one dimension to find the other without stretching.
Matching height: 1920 px
Matching width: enter a height
Calculated values may have fractional pixels. Round to whole pixels when exporting a raster image.

No upload. The image never leaves your device; nothing is saved by this site.
Put this frame to work
A 1080 × 1920 portrait reduces to 9:16. A landscape source at 1920 × 1080 can only fill that shape by keeping roughly 608 pixels of its width and losing the rest.
Resizing preserves a source image's shape; cropping removes edges to fit a different one. Download the crop as PNG or JPEG above.
Common 9:16 pixel sizes
| Width | Height | Pixels |
|---|---|---|
| 720 | 1280 | 921,600 |
| 1080 | 1920 | 2,073,600 |
| 1440 | 2560 | 3,686,400 |
9:16 is 16:9 rotated upright; at the same width it is nearly twice as tall.
