Native macOS hex editor with a brain for file formats
A native macOS hex editor for developers, reverse engineers and security researchers. Open files of any size instantly, decode the bytes under your cursor, parse Mach-O/ELF/PE/PNG/ZIP structure, run checksums and entropy, bookmark what matters
Hey Product Hunt 👋
I'm Shaun, and I built Hexel Editor because every time I needed to look at
raw bytes on my Mac I ended up in something that felt like it was ported from
2003 — or in a terminal, squinting at xxd output.
Hexel Editor is a native macOS hex editor that looks and behaves like a Mac
app. An Xcode-style document window: navigator on the left, a precise hex grid
in the middle, a live inspector on the right.
What it does:
• Opens anything, instantly. Large files are memory-mapped, so a multi-GB
binary opens as fast as a 2 KB one and stays responsive while you scroll.
• Tells you what the bytes mean. The inspector decodes Int/UInt 8–64,
Float32/64, binary, hex and strings at the cursor, little- or big-endian,
toggled instantly.
• Understands real file formats. Built-in parsers for Mach-O, PE, ELF,
PNG, JPEG, GIF, BMP, ZIP, gzip and PDF. Click a parsed field and it jumps
straight to those bytes.
• Finds anything. Hex pattern search with ?? wildcards for don't-care
bytes, text search in UTF-8/UTF-16 LE/BE/ASCII, and Go-to-Offset in hex,
octal or decimal.
• Analyzes. CRC32, MD5, SHA-1, SHA-256, plus entropy and a byte-frequency
histogram over a selection or the whole file.
• Annotates. Named, colored bookmarks and plain-text notes on any byte
range, exportable as .hexel files so you can share your findings.
• Edits safely. Insert/overwrite/delete, read-only mode, unlimited undo,
and atomic saves that won't corrupt the file.
And it's private by design: no network access, no analytics, no tracking. Your
files never leave your Mac.
I'd love to hear what formats you'd want parsers for next — that's the roadmap
I most want your input on. Happy to answer anything in the comments today.
