What is the difference between minifying and beautifying?

Minifying removes every byte that is not needed at runtime — whitespace, comments, semicolons, line breaks — so the file is as small as possible for the browser or parser. Beautifying does the opposite: it re-adds consistent indentation and line breaks so a minified or messy file becomes readable again. Most formats here have one of each.

Which tools also lint, not just format?

Markdown Linter checks style issues like heading levels, code fences, and list consistency, and Email HTML Linter flags cross-client problems such as unsupported flex/grid CSS, non-inline styles, and Outlook rendering traps. The rest focus on minifying or formatting rather than rule-checking.

Will formatting lose my comments?

It depends on the format. XML Formatter preserves comments and CDATA, but YAML Formatter and TOML Formatter warn that comments are lost because of how their underlying parsers work. The tool descriptions call this out so you know before running it on a config file whose comments matter.

Can SQL Formatter handle my database dialect?

Yes. SQL Query Formatter and Minifier supports PostgreSQL, MySQL, SQLite, SQL Server/T-SQL, BigQuery, Snowflake, and more, with control over keyword and identifier casing, indent style, and statement spacing, and shows live size and statement stats.

Code and Markup Minify, Beautify, and Format Tools

Minify and beautify CSS, HTML, JavaScript, JSON, SQL, XML, YAML, TOML, SVG, and VBA, lint Markdown and email HTML, and format code across languages in one hub for production and review workflows.

Overview

What this hub helps you accomplish

This hub groups the two opposite jobs that happen around every code and markup file: shrinking it for production and cleaning it up for review. The minifiers strip whitespace, comments, and redundant markup from CSS, HTML, JavaScript, JSON, and SVG so assets ship smaller. The beautifiers and formatters do the reverse, turning a minified or messy blob into readable, well-indented SQL, XML, YAML, TOML, or VBA. Two linters round out the set: a Markdown style checker and an email-HTML compatibility checker that flags what Gmail, Outlook, and Apple Mail will break. Use it to prepare a build, untangle a minified snippet, or make a config file reviewable before commit.
