Image Resizer

Resize by exact pixels or by percentage. Only changes dimensions — for compression, use the Image Optimizer instead.

Drag & drop an image here, or

Give just one dimension and the other is calculated automatically. Give both with this checked and the image fits within that box without distorting; uncheck it to stretch to the exact box (both required then).
