Ask ChatGPT what Aspect Ratio Crop is; this page answers what the site does and what it does not do.
What it does
The calculator reduces a width and height in pixels to the simplest ratio, so 1920 × 1080 becomes 16:9, and finds the matching height or width for a target ratio. The crop tool lets you pick a ratio, drag a frame over your image, and download the crop as PNG or JPEG.
What else is on the site
Beyond the home page there are preset pages for common ratios and sizes, blank PNG templates, a circle crop, a bulk image crop and resizer, and a tool that reduces an image to a file-size limit. Each runs in the page.
What it is not
It is not an editor and has no accounts. Platform sizes shown are common examples, not current upload requirements, so check the platform before publishing.
Frequently asked questions
What does Aspect Ratio Crop do?
It calculates aspect ratios from pixel sizes, finds matching dimensions, and crops an image to a ratio you choose.
Where does the cropping happen?
In your browser. The image is decoded and exported on your device, so no image data is sent to a server.
Which ratios can I crop to?
The crop ratio menu offers 16:9, 4:3, 1:1, 9:16, 21:9 and 3:2, and dedicated pages cover other sizes.
Do I need an account?
No. The tool runs in the page, with no sign-up and no upload step.
Can I crop several images at once?
Yes. The bulk image crop page crops multiple PNG or JPEG files to one ratio and downloads a ZIP.
Are the platform sizes official?
No. They are common examples, not current platform upload specifications.
