💻 Code & Developer Tools

Minify, beautify, format, compare, and convert code. Built for developers, by developers.

Developers spend a surprising amount of time on tasks that are not writing actual application logic: formatting code for readability, minifying assets for production, testing patterns, converting between syntaxes, and comparing changes across versions. BoltQuickTools bundles all of these common developer utilities into one place, with every tool running entirely in your browser. No accounts, no server-side processing, no waiting.

Minification and Beautification

The CSS Minifier strips comments, collapses whitespace, and shortens property values to produce the smallest possible stylesheet for production deployment. The reverse mode beautifies minified CSS back into readable form with proper indentation. The JS Minifier does the same for JavaScript, carefully preserving strings, template literals, and regex patterns. The HTML Beautifier formats messy markup with consistent indentation while leaving pre-formatted and script blocks untouched, and its minify mode compresses HTML for faster delivery.

Code Formatting and Analysis

The SQL Formatter takes dense, single-line queries and restructures them with proper keyword alignment, indentation, and syntax highlighting. It supports MySQL, PostgreSQL, and standard SQL dialects. The XML Formatter does the same for XML documents, producing clean indented output with a collapsible tree view for exploring complex structures. The Regex Tester provides real-time pattern matching with capture group highlighting, letting you iterate on complex patterns before committing them to your codebase.

Conversion and Comparison

The HTML to JSX converter handles the fiddly differences between HTML and React JSX: converting class to className, transforming inline style strings into JavaScript objects, adjusting event handler names, and self-closing void elements. The cURL to Code tool parses cURL commands and generates equivalent code in JavaScript (fetch and axios), Python (requests), PHP, Go, Ruby, Java, and C#, saving you from manually translating API documentation examples. The Slug Generator helps convert titles and free text into stable URL slugs for docs, blog posts, and API resource paths. The MIME Types Lookup helps confirm correct Content-Type values while configuring servers and API responses.

The Code Diff Viewer compares two code blocks with syntax highlighting, offering both side-by-side and unified diff views with character-level change detection. The Markdown Table Generator provides a visual spreadsheet-like editor that outputs clean Markdown tables, with CSV import and column alignment controls. And the Code Screenshot tool turns code snippets into polished, shareable images with customizable themes and gradient backgrounds.
