Make a 600 × 600 image
Upload a photo and keep the preset width and height. Crop creates exactly 600 × 600 pixels by keeping the centre and trimming excess from the edges. Select Prepare Image to see the result, then download. Choose Fit instead to keep every edge; it may produce a non-square result within the box.
Start with enough original detail
A source at least 600 pixels across the crop area will give a clearer result. Enlarging a smaller picture creates the requested pixel count, but cannot recover detail that was never in the original.
Exact pixels and a file-size limit
The preset preserves exact dimensions. You can add a maximum file size, but UploadMint will not quietly shrink your square to meet it. Enable smaller dimensions only if your destination permits them.
Your image stays with you
UploadMint processes supported images in your browser. Your image is not uploaded to a processing server, and no account is needed. Closing the page clears the working image.
