About Web Utility Lab
Web Utility Lab is a practical collection of browser-based tools for everyday website code and text workflows.
What we build
Web Utility Lab focuses on small, useful tools that help developers, website owners, students, and technical editors work faster with front-end code and common web text formats.
Current tools include an HTML online editor, HTML formatter and compressor, CSS formatter and compressor, JavaScript formatter and compressor, MD5 hash generator, and Base64 encoder and decoder.
The goal is simple: paste code or text, choose an operation, review the result, and copy it back into your workflow.
Our principles
Fast by default
Pages are designed to load quickly and keep the main tool interaction direct.
Browser-first
Tool operations are designed to run in the browser whenever practical.
No account required
The tools are available without signup, login, or account setup.
Clear boundaries
We explain important limits, such as MD5 being a one-way hash and Base64 being encoding, not encryption.
Tool categories
Built around common website tasks
HTML tools
Preview HTML snippets, clean up markup, and compress HTML fragments for easier reuse.
Code formatting
Format or compress CSS and JavaScript snippets for quick cleanup and inspection.
Encoding and hashing
Generate MD5 hashes, compare hash values, and encode or decode Base64 text with Unicode support.
Privacy-minded workflow
The current static version of Web Utility Lab is designed so tool input is processed in your browser. We do not require an account, and the core utility workflows do not need server-side processing.
Even with browser-based tools, you should avoid pasting secrets such as passwords, private keys, access tokens, payment information, or sensitive personal data into any online tool.
