How Image Conversion Works Under the Hood
What image formats are, why you would convert between them, and how client-side HTML5 canvas and Web Workers transform pixel streams.
Zero-Upload Client Architecture Research
Client-Side Image Conversion processes graphic files directly inside the user's web browser without transmitting bytes to external servers. Using the HTML5 Canvas API and multi-threaded Web Workers, the browser decodes source binary formats into an uncompressed RGBA pixel buffer in device memory, applies formatting rules, and encodes the stream into target formats (WebP, PNG, JPG, ICO, SVG) instantly and securely.
What is an image format?
An image format is simply a standardized way of storing visual information in a file. Different formats store that information differently, which affects file size, rendering speed, and what features are supported (like transparency or vector scalability).
Why convert between formats?
Different web situations demand different formats. A hero photograph on a marketing website should be WebP for fast loading. A brand logo requires PNG or SVG for clean transparency. A browser favicon must be ICO for universal compatibility.
Zero-Upload In-Browser Processing
Unlike traditional conversion websites that upload your personal documents and client graphics to unknown remote servers, Squeeze runs 100% inside your browser's sandboxed memory. Your files are never stored, tracked, or sent across the internet.
