How does the QTool.io Image Resizer work?

Accepted Answer

The QTool.io Image Resizer uses the HTML5 Canvas API to resize images entirely in your browser. No images are uploaded to any server. You select or drag images, choose a target size (preset or custom), pick an output format, and download the results instantly.
