HexEd.it

Overview

HexEd.it is a browser-based editor for inspecting and changing binary files and hexadecimal data. It is a strong fit for people who want file analysis without installing a dedicated editor, but not for anyone who requires open-source software.

Because processing happens in the browser, files stay off HexEd.it’s server, according to the maker. Once the app has downloaded on the first visit, it can also work offline, a useful combination for limited-connectivity settings and local file work.

Key features

HexEd.it pairs inspection in multiple numeric formats with bit-wise editing, search and replace, bookmarks, and multiple selections. That makes it more capable than a read-only hex viewer: users can move from examining data to making targeted changes.

It can decode and encode Motorola S-Record and Intel HEX, and identify more than 20,000 file types. Hash lookup can search Google, VirusTotal, MetaDefender Cloud, BitBaan MALab, and Hybrid Analysis without uploading the file. Those tools make it useful for file identification and hash checks as well as direct binary editing.

The feature page says it can process files up to several terabytes, while the manual says it has been tested on files up to 150 GiB. The claims offer different measures of scale, so users working with exceptionally large files should treat the tested size as the clearer practical reference.

Site security measures include HTTPS, a restrictive Content Security Policy, Feature Policy, and Subresource Integrity. The privacy policy names Google Firebase Hosting, Uberspace hosting, Cloudflare CDN, and Sentry error reporting as services the site uses. Local file processing is a meaningful privacy advantage, but it does not mean the service has no third-party infrastructure.

Pricing

Free: free. HexEd.it is free for commercial and non-commercial use, so it suits individual users and organizations that need the editor without a paid plan. There are no paid tiers to weigh against it. The important restriction is licensing: copying the code to another server and selling it is prohibited, and the maker describes the software as not open-source.

Platforms

HexEd.it supports web, Windows, macOS, Linux, iOS, and Android. The browser-based approach gives it broad platform reach without requiring a separate desktop editor, while offline use is possible after the first visit has downloaded the app.

Who it's for

Choose HexEd.it if you need a free way to inspect or edit binary data across devices, identify unfamiliar file types, work offline after an initial visit, or query hashes without sending the file itself. It is less suitable when open-source licensing is a requirement or when your intended use involves reselling a copy hosted on another server.

Pros and cons

Pros

• Local processing and offline use: Files are processed in the browser rather than uploaded to HexEd.it’s server, and the app can run offline after its first download.
• Broad analysis toolkit: Numeric-format inspection, bit-wise editing, search and replace, bookmarks, multiple selections, and format conversion support both investigation and modification.
• File and hash identification: It identifies more than 20,000 file types and can query five named hash-search services without uploading the file.
• Free commercial use: The free plan permits commercial and non-commercial use.

Cons

• Not open-source: Users who need to inspect or modify open-source code should choose another editor.
• Resale restriction: Copying the code to another server and selling it is prohibited.
• Third-party services: Its privacy policy names hosting, CDN, and error-reporting providers, so local file processing should not be mistaken for an infrastructure-free service.

Alternatives

Hex Editors is the broader category directory for comparing options. Consider these alternatives when their licensing, platform coverage, or specific editing scope better matches your needs:

• Bedrock Viz is a free, GPL-2.0-licensed option for Minecraft Bedrock Edition worlds, with web, Windows, macOS, and Linux support. Pick it when that world-specific scope and open license matter more than HexEd.it’s general binary-editing purpose.
• BinEd is a free and open-source editor available on web, Windows, macOS, Linux, and Android. Choose it if open-source licensing is essential or you need an Android option.
• dhex is a free option for Linux and macOS. Consider it if those are your target platforms and you prefer an alternative to a browser-based editor.
• Hecate is free MIT-licensed software for Linux, macOS, and Windows. Pick it when that license and desktop platform coverage are a better fit.
• ImHex is a free, open-source hex editor for Linux, macOS, and Windows. Choose it if open-source desktop software is your priority.
• REHex is a free, GPL-2.0-licensed option with Windows, macOS, and Linux packages. Consider it when you want those desktop packages under that license.
• wxHexEditor is a free hex editor and disk editor for Linux, macOS, and Windows. Choose it if disk editing is part of your need.
• wxMEdit supports text, column, and hex editing on Linux, macOS, and Windows; its hex mode supports files up to 32GB. Pick it when those editing modes fit your work and that stated file limit is sufficient.

Verdict

HexEd.it is the right choice for people who want free, browser-based binary inspection and editing with offline use, broad file identification, and hash lookup. Its local processing is a practical strength, but the lack of open-source licensing and the restriction on reselling a hosted copy are clear reasons to look elsewhere.
