How does PNG to JPG conversion work?
PNG to JPG conversion involves moving from a lossless format to a lossy one. The JPG compression algorithm divides the image into 8x8 pixel blocks and uses a technique called Discrete Cosine Transform (DCT) to discard color frequencies that the human eye doesn't easily perceive. This is what allows JPG to be drastically smaller than PNG.
Our converter uses WebAssembly to run this process locally. When processing the file, the engine flattens any PNG transparency layers onto a solid white background and applies high-quality quantization. The result is an optimized JPG file, perfect for fast sharing, while maintaining security and privacy as your photos are never uploaded to external servers.
