Hex Editor Neo vs HexEd.it

Hex Editor Neo is Windows software for editing binary files, including files of any size and physical disks such as HDDs, SSDs, optical discs and USB disks. Editing tools cover typing, cutting, copying, pasting, filling, deleting, inserting, importing and exporting data. Search can match binary, hexadecimal, decimal, octal, float, double, character, ASCII and Unicode patterns, including wildcards; replacement supports arbitrary-length patterns and regular expressions. The editor provides unlimited undo and redo, with operation history that can be saved or loaded. It creates 32-bit and 64-bit binary patches, as well as self-installing executable patches with file-hash checking. Portable installation avoids registry changes, shell extensions and shortcuts. More than 130 text encodings are supported, including UTF-8 and UTF-16. Settings can be stored in the registry, local files or shared locations such as OneDrive and Dropbox. The Free Hex Editor Neo plan costs nothing and includes basic editing features. Free Edition users receive limited or no support; email and phone technical support is provided to registered users of Standard, Professional and Ultimate editions.

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.
