In the "Find" field, you can use JavaScript RegExp or switch RegExp off and search for plain text only. Flags: g — all matches, i — case-insensitive, m — multi-line mode. An empty replacement deletes the match.

About Editor

Online HTML Editor with Live Preview

Replitor is built for fast, practical HTML cleanup and editing. Your source stays on the left, a live WYSIWYG preview stays on the right, and both views stay in sync while you work.

Beyond plain editing, the editor includes Batch Replace, Find & Replace with RegExp, reusable template chains, quick replace buttons, optional change history, and local snapshot protection for the current tab.

Live Preview Batch Replace Find & Replace RegExp and JSON Private Local Work

What’s already built in

HTML editing with line numbers, optional highlighting, wrap control, and quick text sizing.
Live preview in an iframe with visual editing and sync back to the source code.
Block selection, block deletion, cleanup of empty elements, and structure-safe editing.
Ready-made and custom templates for cleanup, plus import and export of your own sets.
Batch Replace, RegExp-based Find & Replace, JSON chains, and quick-access replace buttons.
Optional undo history for the current tab and automatic local snapshot recovery after accidental refreshes.

Why it’s easy to use

You don't have to choose between raw code and visual verification. You can edit HTML directly, click into the preview to adjust content, run a single Find & Replace, or build a full Batch Replace workflow from reusable blocks.

That makes the editor especially useful for markup coming from CMS exports, AI tools, email builders, old admin panels, or messy copy-paste jobs. Clean it up, save the pattern, and reuse the same workflow again in a few clicks.

Local Work and Project Development

The editor works on the user's device. Your HTML, custom templates, quick replace buttons, and current snapshot are not sent anywhere for processing. Persistent user data stays in localStorage, while temporary history and session-only safety data stay in sessionStorage for the current tab.

Replitor is being developed in spare time and expanded step by step. Current work is focused on better speed for large documents, safer visual editing, more practical replacement workflows, and more editor modes built on the same core interface.

Most of the icons in the editor interface are taken from Phosphor Icons.
