⚠️ Technical Limitations & Best Practices
Converting lossy formats (like JPG) to lossless formats (like PNG) preserves existing visual quality but cannot restore detail lost in previous compression. Always maintain a backup of your original source files. Output metrics (such as exact byte size and visual sharpness) are determined by input quality, color depth, and complexity.
