Why Use This Tool
Unlike online image resizers that upload your images to remote servers, this tool processes everything locally using your browser's built-in Canvas API. There are no file size limits, no queue waiting, and your images never leave your computer. This makes it ideal for resizing sensitive images, batch processing, and situations where privacy matters.
Privacy
All image processing happens locally in your browser. Images are never uploaded to any server.
