OH MY SVG

Enhance your WordPress website with the power of SVG images using the OH MY SVG plugin. Easily add, manipulate, and optimize SVG images directly within the Gutenberg block editor.

Unlike traditional image blocks, this plugin provides an intuitive interface that allows you to incorporate SVG icons, illustrations, or HTML snippets effortlessly. Experience the convenience of automatic markup sanitation, SVGO optimization, and a range of built-in utilities like color customization, stroke adjustments, and element stripping.

🌟 Smart Dual Storage Modes (New!)

One of the biggest issues with using SVGs in WordPress is database bloat. If you paste a heavy SVG directly into the editor, its entire XML markup gets saved into every single post revision, quickly cluttering your database. OH MY SVG solves this by offering two distinct storage modes:

1. Inline Mode (Best for tiny icons): The SVG markup is embedded directly within the page’s HTML. This drastically reduces page load time by eliminating server requests and conserving bandwidth. Ideal for small, lightweight vectors.
2. Media Library Mode (Best for heavy illustrations): To prevent database bloat, this mode saves the SVG behind the scenes as a custom post meta attached to the WordPress Media Library. The plugin automatically generates a lightweight PNG proxy image so you can see it in your media grid. On the front end, it renders cleanly using a data URI, keeping your post content light, your database clean, and your page performance high.

Unleash your creativity with endless possibilities—animate SVGs using CSS or JavaScript, modify inner colors, and scale infinitely without losing sharpness.

Svg are awesome because:

• ✌️ Pixel Perfect: SVGs render sharply on any screen and resolution.
• 🗄️ Zero Database Bloat: Choose to link heavy SVGs to the Media Library, keeping your post content and revisions lightweight.
• 🎨 In-Editor Editing: Customize colors, add strokes, and remove fills to create variations directly in Gutenberg.
• ⚡ Performance Boost: Use inline SVGs to save dozens of HTTP requests and reduce server download bandwidth.
• 🛠️ Built-in Optimizer: Automatically compress and optimize markup using the integrated SVGO tool.
• 🎉 Developer Friendly: Easy to animate with CSS and JavaScript since they render as DOM elements or standard image tags.

🔒 Security First

The OH MY SVG plugin prioritizes your website’s security. By default, WordPress blocks raw SVG file uploads due to severe XML/XSS vulnerabilities. This plugin keeps that protection intact. Instead of allowing dangerous direct .svg uploads, our plugin safely processes the SVG markup within the editor using a robust JavaScript purifier (DOMPurify). When saving to the Media Library, it creates a harmless PNG proxy file and securely stores the sanitized SVG string as an attachment metadata field. SVGs cannot be maliciously uploaded from the website “side” (e.g., frontend forms); only trusted users with editor permissions can include them.
