A form needs 600 × 600 px: crop to square first with the Image Cropper, then resize to 600 × 600.

Frequently asked questions

Will enlarging an image add detail?

No. Upscaling interpolates existing pixels, so large enlargements look soft. Resizing down is where quality is preserved.

Which resampling is used?

The browser’s high-quality image smoothing. Large reductions are done in steps of one half, which avoids the jagged look of single-step downscaling.
