What this tool does

Resize an image to exact pixels, a percentage, or a useful preset.

Method

The browser decodes the image and applies the selected fit, fill, or crop transform to exact pixel dimensions before encoding the chosen output format.

Example

Resize a 4000×3000 photo to 1200×630 while preserving the center crop for a social preview.
