How Local In-Browser Converters Protect Your Personal Privacy

When you click "Upload" on a standard conversion website, your file travels over the internet to a server owned by a third party. But what happens next?
The Security Risks of Server-Based Utilities
Many free online conversion services monetize by running analytical engines on your files. They may extract EXIF geolocation metadata, scan documents for text, or cache the photos indefinitely. For screenshots containing database credentials, business metrics, or personal faces, this is a severe privacy breach.
What is an In-Browser Converter?
An in-browser converter uses JavaScript scripts loaded into your browser. Your CPU and graphics processor decode the file and draw it onto a canvas local to your sandbox. The file never leaves your machine. Your network data is saved, and your data remains 100% secure.
