What HexEd.it is
HexEd.it is a free, browser-based hex editor for inspecting and editing binary files and hexadecimal data. Processing takes place in the browser, and the site says file data is not uploaded to its server. After the first visit downloads the app, it can be used offline. Editing and analysis tools include viewing data in multiple numeric formats, bit-wise editing, 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 search 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 says it has been tested on files as large as 150 GiB. The site lists HTTPS, a restrictive Content Security Policy, Feature Policy, and Subresource Integrity among its security measures. HexEd.it is free for commercial and non-commercial use, but the maker says it is not open-source.

The full review of HexEd.it
Overview
HexEd.it is a browser-based hex editor for inspecting and changing binary files. It is best for people who want broad file-analysis tools without installing a dedicated editor. Its main drawback is that it is free software, but not open-source.
Key features
HexEd.it supports inspection in multiple numeric formats, bit-wise editing, search and replace, bookmarks, and multiple selections.
It decodes and encodes Motorola S-Record and Intel HEX files, and can identify more than 20,000 file types. Hash lookup can query Google, VirusTotal, MetaDefender Cloud, BitBaan MALab, and Hybrid Analysis without uploading the file. These capabilities make it useful for identifying unfamiliar files and checking hashes alongside editing them.
File processing takes place in the browser, and HexEd.it says file data is not uploaded to its server. After the app has downloaded on the first visit, it can work offline. Those are meaningful advantages for people who want files to remain on their device or need to work without a connection. The site also uses HTTPS, a restrictive Content Security Policy, Feature Policy, and Subresource Integrity. Its privacy policy names Google Firebase Hosting, Uberspace hosting, Cloudflare CDN, and Sentry error reporting, so local file processing does not mean the site uses no third-party services.
The feature page says HexEd.it can process files up to several terabytes; the manual says it has been tested on files as large as 150 GiB. The tested-size figure is the more concrete guide for users deciding whether it suits exceptionally large files.
Pricing
HexEd.it has one plan: Free, at free. It covers commercial and non-commercial use, with no seat or quota terms stated. The restriction is on redistribution: copying the code to another server and selling it is prohibited. There is no paid tier described, so users who need open-source licensing should look elsewhere rather than expect a higher plan to change that limitation.
Platforms
HexEd.it supports web, Windows, macOS, Linux, iOS, and Android. The browser-based design gives it reach across desktop and mobile platforms; offline use is possible after the initial app download.
Who it's for
Choose HexEd.it if you want a free editor that combines binary editing, file-type identification, hash lookup, and offline access, particularly when keeping file contents off the editor's server matters. It is a poor fit if open-source software is a requirement, or if you need a file-size guarantee beyond the manual's tested maximum.
Pros and cons
- Pro: Local browser processing and offline use after the first download let users work without sending file data to HexEd.it's server or relying on a continuing connection.
- Pro: Numeric inspection, bit-wise editing, search and replace, bookmarks, and multiple selections support detailed work rather than read-only inspection.
- Pro: File identification and hash lookup add practical analysis tools, with hash searches that do not upload the file.
- Con: It is not open-source, which rules it out for users who need to inspect or adopt open-source software.
- Con: The manual's tested maximum is 150 GiB, even though the feature page describes processing files up to several terabytes; users with unusually large files should weigh that distinction.
Alternatives
For another free option with a published open-source editor and an Android app described as a free service, consider BinEd; it supports web, Windows, macOS, Linux, and Android.
Bedrock Viz is a free, GPL-2.0-licensed option for Minecraft Bedrock Edition worlds, if that is the kind of file you need to work with.
Hecate is a free MIT-licensed alternative for Linux, macOS, and Windows.
REHex is a free GPL-2.0 option with Windows, macOS, and Linux packages.
dhex is a free alternative for Linux and macOS.
ImHex is a free open-source hex editor for Linux, macOS, and Windows.
wxHexEditor is a free hex editor and disk editor for Linux, macOS, and Windows.
Bless is a free GNU GPL-2.0-or-later option for Linux and Windows, distributed as a source build.
Verdict
HexEd.it is a strong choice for people who want a free, cross-platform binary editor with local processing, offline use, and useful file-identification tools. Its range of editing and analysis features is the reason to choose it; its non-open-source status is the clearest reason to pick another editor.
