HTMLmend

HTMLmend turns any already-made HTML slide into something you can fix without touching code. Open the page, click the toolbar icon, and a small editing panel appears. Click an element to select it, then change its text, color, size, font, position, and more — then save the whole thing as one self-contained HTML file. It's a mending tool, not a from-scratch builder: perfect for tidying up AI-generated slides (decks exported as a single HTML file) before you present or share them. ■ WHAT YOU CAN DO • Click to select any element — the highlight stays aligned even on transform:scale() slides • Edit text directly (double-click) with rich formatting: bold / italic / underline / strikethrough, align, lists, links • Change text color with a built-in picker — preset palette + free selection (saturation/brightness, hue, HEX, eyedropper) • Adjust font size (slider or number), font family, and line height • Move and resize elements (Move mode + drag, with scale-aware math) • Recolor the whole deck at once by editing the theme (CSS variables) • Replace / insert / delete images, edit alt text, and embed video (YouTube / Vimeo / MP4) • Unified Undo / Redo across every action (Ctrl+Z / Ctrl+Shift+Z) • Navigate slides (Prev / Next) • Dock the panel left or right, or float it; collapse it when floating • Built-in help screen explaining every feature • Export a single HTML file with CSS and images embedded (editing UI removed), or copy just your CSS changes • Reset to the original file to discard all edits ■ PRIVACY • 100% local. Your pages and edits never leave your browser — no servers, no analytics, no tracking. • No third-party code is bundled and no remote code is loaded. • Minimal permissions: it only acts on the current tab when you click the icon. ■ HOW TO USE 1. Open the HTML slide you want to edit (a local file:// page works too). 2. Click the HTMLmend toolbar icon to turn on edit mode. 3. Click an element to edit it; double-click text to retype it; use Move mode to drag. 4. Click "Save as single HTML" to export. ■ Note: Pages on http(s) work as-is. To edit a local file opened as file://, turn on "Allow access to file URLs" on the extension's Details page (chrome://extensions), or serve the file over http(s).
