How to use Code & Markup Formatter

Format, validate, or minify popular code and markup with browser-only, language-aware parsers.

1. Paste, type, or drag and drop a supported text file into the input area.
2. Choose the options that match your intended result.
3. Select “Run tool” or press Ctrl/Command + Enter, then copy, download, or move the result back into the first input for another pass.

What the result means

Formatted, validated, or minified inert source text. Converted code is never executed.

Privacy and safety

This utility is loaded as browser code and processes your input only in this tab. OmniCastConverter has no upload endpoint and never stores your content, filenames, tokens, or secrets. Generated markup and code are shown as inert text and are never executed.

Limitations

• Validation checks syntax, not types or project-wide semantics. TypeScript minification requires compilation first. HTML minification can affect significant inline whitespace.
