Why convert JPEG to PNG?

PNG stores pixels losslessly, so once a JPEG becomes PNG no further generation loss creeps in while you crop, annotate, or composite it. It's also the format most design tools, documentation systems, and app-store screenshot uploaders expect. Note that PNG cannot undo compression artefacts already baked into the JPEG — it only stops new ones appearing.

How it works

Drop your JPEG 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.
