Resize Image
Upload an image, adjust the width and height, and download the result.

How it works
With "Keep aspect ratio" checked, changing the width automatically adjusts the height (and vice versa), so the image never ends up distorted. Uncheck it if you want to set width and height fully independently. Cutting pixels cuts weight: a 4000 × 3000 photo (12 megapixels) taken down to 1600 × 1200 ends up with 84% fewer pixels, which usually shrinks the file a lot. For the web, blog images rarely need more than 1600 px of width; for icons and avatars, a few hundred pixels are enough. Making an image larger does not create new detail: the software just interpolates the pixels that already exist, and the result gets blurrier the bigger the enlargement. If you need a large version, start from the original image, not one that was already reduced.
