Security
Security is built around a simple principle: your images never leave your device.
Browser-only processing
Image resizing, compression, and conversion run locally using the Canvas API, File/Blob APIs, and Web Workers. There is no server-side image processing and no file upload step.
Network access
The app only fetches the code and assets needed to render the interface. Your image data is kept in memory on your device and is not transmitted over the network.
Best practices
Use HTTPS to access the site and keep your browser updated. If you are working with sensitive files, consider running the tool offline after the page loads.
