JPG to PNG converter

This tool performs a JPG (JPEG) to PNG conversion focused on format change and color fidelity. It outputs a PNG image suitable for web, UI, and print tasks where transparency or higher fidelity is required. The process conceptually decodes the JPEG into a pixel array, standardizes color data to RGB(A), and re-encodes as PNG. If the source contains an alpha channel (rare for JPEGs, which are typically opaque), that transparency is preserved in the PNG; otherwise the output is fully opaque. The tool emphasizes deterministic results, stable color handling, and a predictable file size, enabling reliable asset pipelines. Core features include single-file input, lossless PNG encoding, optional alpha preservation, and straightforward error reporting. Use cases include preparing product imagery with transparent backgrounds for catalogs, UI assets that require alpha channels, and marketing graphics that demand PNG compatibility across platforms.
