HextEdit is a native hex editor for macOS, built for anyone who needs to look inside a file at the byte level. Open any file and you see its raw bytes beside their text form, ready to inspect or change. Developers use it to patch executables, check file headers and hunt down data problems a text editor cannot show. It stays quick even with big files.

FAQs

What is a hex editor used for?

It shows and edits the raw bytes inside a file, which helps with patching, checking headers and fixing data.

Should I edit my only copy of a file?

No. Always work on a copy. Changing the wrong byte can make a file unreadable, and a spare copy lets you start again safely.

Does HextEdit work on Apple Silicon?

Yes. It runs natively on Apple Silicon and on Intel Macs, so both kinds of machine get full speed without translation layers.
