Smart Cropper

What does Smart Cropper do?

Smart Cropper is a precision image cropping tool with built-in presets for social media (Instagram, Facebook, LinkedIn, YouTube), print paper sizes at 300 DPI, and common aspect ratios — or set an exact custom size in pixels or centimetres. Drag the crop box directly, resize from any corner, or use the 9-point alignment grid to snap it to a specific position instantly.

The Scale Image slider resizes the source image itself (useful for working with a smaller preview of a very large photo), which is separate from cropping — crop selects a region, scale changes the underlying image size. Export as JPG, PNG, or WebP once you're happy with the selection.

Frequently asked questions

Is Smart Cropper free to use?

Yes, completely free with no account or usage limit.

What preset sizes are included?

Social media presets (Instagram Square/Portrait/Story, Facebook Post/Cover, LinkedIn Banner, YouTube Thumbnail), print paper sizes at 300 DPI (A4, A5, US Letter), and common ratios (4:3, 3:2, 21:9), plus a free-form option with no restriction.

How does image scaling differ from cropping?

Scaling resizes the entire source image up or down. Cropping selects a rectangular region of whatever the current scaled image looks like. They work together: scale first if you need to fit a very large image into the workspace, then position your crop box.

Is my image uploaded anywhere?

No. Cropping and scaling happen locally in your browser using the Canvas API — your image never leaves your device.

Can I crop to an exact custom size in centimetres?

Yes — switch to the Custom tab, select "Centimeters" as the unit, and enter your width and height. This converts to pixels at 300 DPI, matching the same standard used by the built-in paper size presets.
