hexed.it
What it is
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.

HexEd.it in depth
Read the full write-up
Overview
HexEd.it is a browser-based tool for inspecting and editing binary files, best suited to people who want a capable hex editor without installing one. Its combination of local processing and offline use is compelling; the clear drawback is that it is not open-source.
File processing happens in the browser, and the maker says file data is not uploaded to its server. After the app downloads on the first visit, it can run without an internet connection. That suits work on sensitive files, though hash lookups can still query external services.
Key features
HexEd.it supports inspection in multiple numeric formats, bit-wise editing, search and replace, bookmarks, and multiple selections. This makes it useful for both understanding binary data and making focused changes, rather than merely viewing a hex dump.
It can encode and decode 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 uploading the file. Those integrations add useful identification and lookup options, but users should distinguish a local file from the hash sent to an external service.
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 is the more concrete guide for especially large jobs. The site says it 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.
Pricing
HexEd.it is free for commercial and non-commercial use. The Free plan costs nothing, with no paid tier or trial described. The maker prohibits copying the code to another server and selling it. This is an unusually straightforward fit for individuals and organizations that need the editor without a subscription, but free use does not make the software open-source.
Platforms
HexEd.it supports web, Windows, macOS, Linux, iOS, and Android. The browser-based approach and offline mode make it a flexible option across desktop and mobile platforms, without requiring a separate installed editor.
Who it's for
Choose HexEd.it if you need broad binary inspection and editing tools, file-type identification, or Intel HEX and Motorola S-Record support, and value browser-based local processing. It is less suitable for people who require open-source software or want to copy and resell the code.
Pros and cons
Pros: Local browser processing and offline use reduce reliance on a server connection for file work.
Pros: Numeric inspection, bit-wise editing, search and replace, bookmarks, and multiple selections support more than basic hex viewing.
Pros: Free commercial and non-commercial use, with support for six platforms.
Cons: It is not open-source, which rules it out for users who require open code.
Cons: Hash lookup queries external services, so it is not entirely self-contained even though the file itself is not uploaded.
Alternatives
Hex Editors is the broader category directory for comparing options.
Bedrock Viz is a free, GPL-2.0-licensed option for Minecraft Bedrock Edition worlds, rather than a general-purpose hex editor.
BinEd is free and open source, with an Android app described as a free service; pick it if open licensing matters more than HexEd.it's specific file-identification and hash-lookup features.
REHex is a free GPL-2.0-licensed choice with Windows, macOS, and Linux packages for users who prefer a desktop editor.
010 Editor is a paid alternative with a free trial for Linux, macOS, and Windows.
Hecate is free MIT-licensed software for Linux, macOS, and Windows, with no plan limits stated.
Hex Editor Neo offers a free Windows plan with basic editing features and limited or no support, plus a free trial.
CombineZP is a free GPL-licensed Windows option.
dhex is a free option for Linux and macOS.
Verdict
HexEd.it is a strong choice for people who want a free, cross-platform binary editor with substantial inspection tools, file identification, and local offline processing. Choose another editor if open-source licensing is a requirement.
Verdict
HexEd.it sets out a substantial set of binary editing and identification tools, along with its browser-based processing and offline use. It is free, but the maker explicitly says the software is not open-source.
