BMP stores every pixel uncompressed, so files are huge. PNG keeps the exact same pixels but applies lossless compression, typically shrinking a bitmap by 60-90% with no quality loss — and it supports transparency, which BMP does not.
Drop your BMP file above and Morphix decodes it locally, then re-encodes it as PNG using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
