In their own words
HexEd.it
HexEd.it is a browser-based editor for inspecting and changing binary files and hexadecimal data. Processing takes place in the browser, and the site says it does not send file data to its server. Once the app has been downloaded during a first visit, it can also work offline. Analysis and editing tools include viewing data in multiple numeric formats, bit-wise changes, search and replace, bookmarks, and multiple selections. HexEd.it can decode and encode Motorola S-Record and Intel HEX files, and identify more than 20,000 file types. Its hash lookup can query Google, VirusTotal, MetaDefender Cloud, BitBaan MALab, and Hybrid Analysis without uploading the file. The feature page says it can process files up to several terabytes; the manual reports testing on files up to 150 GiB. The site lists HTTPS, a restrictive Content Security Policy, Feature Policy, and Subresource Integrity as security measures. It is free for commercial and non-commercial use, but the maker says it is not open-source.
REHex
REHex is a free hex editor for reverse engineering and other work with binary data, available for Linux, macOS and Windows. It supports files larger than 1 TB, decodes integer and floating-point values, and displays machine-code disassembly inline. Users can compare whole files or selected regions side by side, map virtual addresses, and highlight or annotate byte ranges. Editing and analysis tools include bit editing, checksumming and bitmap visualization, along with common encodings such as ASCII, Unicode and ISO-8859-X. REHex imports and exports Intel HEX files. Binary Templates can annotate data automatically, while Lua scripting and plugins extend its functionality. Downloads include Windows installers and ZIP archives, a macOS DMG, and 32-bit and 64-bit Linux AppImages; packages are also documented for Debian, Ubuntu, Fedora, Red Hat Enterprise Linux, FreeBSD and openSUSE. The project identifies its license as GPL-2.0. The download page lists version 0.64.0, released on 2026-04-03, as the latest release. Bug reports and feature suggestions can be submitted as GitHub issues.
