Why convert RAR to 7Z?

RAR needs licensed software to create and is often blocked by corporate policies. 7Z is free and open, compresses just as well, and is supported by 7-Zip, Keka and most modern archive managers.

How it works

Drop your RAR file above and Morphix decodes it locally, then re-encodes it as 7Z 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.
