HexEd.it

HexEd.it is a browser-based tool for inspecting and editing binary files and hexadecimal data. The site says processing happens in the browser and file data is not uploaded to its server. After the first visit downloads the app, it can be used without an internet connection. Editing tools include viewing data in multiple numeric formats, bit-wise editing, search and replace, bookmarks, and multiple selections.

The editor 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 describes testing 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 is not open-source. It is listed for web, Windows, macOS, Linux, iOS, and Android.

HexEd.it combines browser-based binary editing with offline use after its initial download. It is free for commercial and non-commercial use, but the maker says it is not open-source.

HexEd.it may suit people who need to inspect or modify binary data in a browser, including when offline after the initial visit. Its format decoding and hash lookup tools may help with file analysis.

Overview

HexEd.it is a browser-based editor for inspecting and changing binary files and hexadecimal data. It is best suited to people who want a capable hex editor without installing one. Local browser processing and offline use are compelling advantages; the lack of an open-source license will rule it out for some.

Key features

HexEd.it offers inspection in multiple numeric formats, bit-wise editing, search and replace, bookmarks, and multiple selections. That mix supports focused changes as well as analysis, making it useful when a file needs more than a quick look at its hexadecimal values.

It can decode and encode Motorola S-Record and Intel HEX files, and identify more than 20,000 file types. Hash lookup can query Google, VirusTotal, MetaDefender Cloud, BitBaan MALab, and Hybrid Analysis without sending the file itself. These capabilities extend the editor into file identification and hash research while keeping the file local.

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 tested figure offers a more concrete guide for demanding work, while neither claim guarantees performance on every file or device. The site 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 has no external service providers.

Pricing

There is one free plan, with no paid tier to unlock. That makes it a straightforward choice for individual and commercial use alike, subject to the restriction on copying the code to another server and selling it. Free software does not mean open-source here: the maker explicitly says HexEd.it is not open-source, a meaningful drawback for users who need to inspect or modify the source.

Platforms

HexEd.it supports web, Windows, macOS, Linux, iOS, and Android. Its browser-based design avoids a conventional installation, and after the first visit downloads the app, it can work without an internet connection. That combination suits users who move between devices or need to work offline, though offline use depends on having made that initial visit.

Who it's for

Choose HexEd.it for browser-based binary analysis, targeted hex editing, file-type identification, or hash lookups when keeping the file off the editor's server matters. Its broad platform support and offline mode help when a desktop installation is inconvenient. Look elsewhere if open-source software is a requirement.

Pros and cons

Pros

• Files are processed in the browser and are not uploaded to HexEd.it's server, according to the maker.
• It can work offline after the initial download, useful when connectivity is unavailable.
• Editing, file identification, S-Record and Intel HEX support, and hash lookup cover more than basic hex viewing.
• Commercial and non-commercial use are both free.

Cons

• It is not open-source, which makes it a poor fit for users who require source access.
• Offline access requires an initial visit to download the app.
• The privacy policy names several hosting, CDN, and error-reporting services, so the site still relies on external providers.

Alternatives

Hex Editors is the category directory for comparing more options. Consider BinEd if you want a free, open-source editor with broad desktop and web platform support, including Android; GNU hexedit if Linux and the GNU GPL are the priorities; or Hex Fiend if you use macOS and want an open-source option under a BSD-style license. Hecate is another free option for Linux, macOS, and Windows, with MIT-licensed software and no plan limits stated. dhex is a free alternative for Linux and macOS. For a different specialized use, Bedrock Viz is free, GPL-2.0 licensed software for Minecraft Bedrock Edition worlds; CombineZP is a free, GPL-licensed Windows option whose referenced compiled version is 1.0 (x86). Windows users who want a freemium product can consider Hex Editor Neo, whose free tier has basic editing features and limited or no support.

Verdict

HexEd.it is a strong choice for people who need a versatile hex editor across desktop and mobile platforms, especially when local file processing, offline access, or a zero-cost commercial license matters. Its focused editing and analysis tools give it practical range without requiring a desktop installation. The main reason to choose something else is the lack of open-source access; users who need that should consider BinEd, GNU hexedit, or Hex Fiend according to their platform.
