Image Resizer
Resize an image by exact width, height or percentage — the ratio stays locked unless you turn it off.

How it works
KadiTools draws your image onto an in-memory canvas at the new dimensions you set, then exports it in its original format. With the aspect ratio locked, changing the width updates the height for you, and the percentage slider scales both at once.
FAQ
Will resizing distort my image?
Not if you keep the aspect ratio locked — width and height scale together. Unlock it if you want to stretch the image to an exact box.
Can I make an image bigger?
Yes, up to 200%, though enlarging a photo beyond its original size can make it look soft since no new detail is added.
