Description

CodeWash Studio at a glance

CodeWash Studio is an editor-first code cleanup tool. Pick a preset (Prettify, Minify, HTML Wash) or enable quick toggles (comments, format, minify, HTML wash, validate). Click Run (or use Ctrl/⌘+Enter) and the tool generates a cleaned result, automatically jumps to it, and updates a split diff view that shows Removed vs Added side-by-side.
You can copy or download the result, and export the diff as a .diff file.

Non-blocking drag & drop: drop a file to load it without covering the editor. Primary Run action: Run is always prominent next to the preset selector. Split diff review: quickly scan removed lines and added lines in separate columns (stacks on mobile). Resizable editors: both source and result can be resized vertically. Privacy-first: everything happens in the browser; nothing is uploaded or stored server-side.
