How Resizing Works
When you upload an image:
- The tool reads the original width and height.
- Based on your settings:
- If both Width & Height are set → it uses those exact dimensions.
- If only Width is set → height is calculated automatically to keep the same ratio.
- If only Height is set → width is calculated automatically.
- The image is then drawn on a hidden HTML canvas at the new size.
- If you choose a target Size (KB), the tool adjusts the image quality step-by-step to match that size as closely as possible.
- Finally, it creates a new image file (JPG or PNG) ready to download.
You don’t have to worry about the technical part — just pick the size you want and download the result.
