Crop image to square
Upload your image and crop it to a perfect square (1:1 aspect ratio). The crop box is locked to equal width and height, so dragging automatically keeps it square. Download as PNG or JPEG. Everything runs in your browser.

How it works
The tool reads your image into browser memory and displays it in an interactive crop preview. Drag the crop box to reposition it, or pull the corner handles to resize. When you click Crop & download, the Canvas API draws the selected region to an offscreen canvas in your browser tab and exports it as a file.
Processing runs in your browser
The Canvas API processes the crop operation locally, and the resulting file is downloaded directly to your device. Our servers are not involved at any point.

After cropping, scale the result with resize image. To switch the saved format, use the image converter. For turning a sideways photo upright before cropping, see image rotate.
Frequently asked questions
- Is my profile photo uploaded while I crop it?
- The square is cut out in this tab: the Canvas API draws the selected area onto a new canvas the size of your selection and encodes it as JPEG or PNG. Our servers are not involved at any point.
- What size will the square crop be?
- The output size matches the pixel dimensions of your crop selection. Drag a larger crop area for a higher-resolution square.
- Can I use this for a profile photo?
- Yes. Most profile photo fields on social platforms accept square images. Crop to 1:1, then resize to the required pixel dimensions if needed.
- What format should I download?
- PNG for quality-critical images or those with transparency; JPEG for smaller file sizes. Profile photos typically work well as JPEG.
