Helpful information and limitations

Image conversion can change compression, color profile, alpha transparency, metadata, animation, or file size. A TIFF/HEIC/RAW/CR2 input may rely on format-library or browser support. Always check the actual output MIME type and visual result. Keep an untouched original. Output can vary with file content, browser support, memory, and third-party library versions.
