Crop creates exactly 300 × 300 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.
A 300-pixel square works best when the subject is easy to recognise at a small size. Tiny text may become hard to read. Inspect the downloaded file at 100% scale before using it.
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.
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.
Fit preserves the whole image and its aspect ratio. A 3:2 photo becomes 300 × 200 inside a 300 × 300 box. Keep the preset Crop mode when you need exactly 300 × 300; it trims the edges without stretching the subject.
JPG suits an ordinary photo and fills transparent areas with white. PNG or WebP can keep a transparent logo. Use a format accepted by the destination and inspect small text at the final 300-pixel size.
