<p>Enhance your WordPress website with the power of SVG images using the <strong>OH MY SVG</strong> plugin. Easily add, manipulate, and optimize SVG images directly within the Gutenberg block editor.</p>
<p>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.</p>
<h3>🌟 Smart Dual Storage Modes (New!)</h3>
<p>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. <strong>OH MY SVG solves this by offering two distinct storage modes:</strong></p>
<ol>
<li><strong>Inline Mode (Best for tiny icons):</strong> 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.</li>
<li><strong>Media Library Mode (Best for heavy illustrations):</strong> 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.</li>
</ol>
<p>Unleash your creativity with endless possibilities—animate SVGs using CSS or JavaScript, modify inner colors, and scale infinitely without losing sharpness.</p>
<h3>Svg are awesome because:</h3>
<ul>
<li>✌️ <strong>Pixel Perfect:</strong> SVGs render sharply on any screen and resolution.</li>
<li>🗄️ <strong>Zero Database Bloat:</strong> Choose to link heavy SVGs to the Media Library, keeping your post content and revisions lightweight.</li>
<li>🎨 <strong>In-Editor Editing:</strong> Customize colors, add strokes, and remove fills to create variations directly in Gutenberg.</li>
<li>⚡ <strong>Performance Boost:</strong> Use inline SVGs to save dozens of HTTP requests and reduce server download bandwidth.</li>
<li>🛠️ <strong>Built-in Optimizer:</strong> Automatically compress and optimize markup using the integrated SVGO tool.</li>
<li>🎉 <strong>Developer Friendly:</strong> Easy to animate with CSS and JavaScript since they render as DOM elements or standard image tags.</li>
</ul>
<h4>🔒 Security First</h4>
<p>The OH MY SVG plugin prioritizes your website’s security. By default, WordPress blocks raw SVG file uploads due to severe XML/XSS vulnerabilities. <strong>This plugin keeps that protection intact.</strong> Instead of allowing dangerous direct <code>.svg</code> 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.</p>

<p>Safe SVG is the best way to Allow SVG Uploads in WordPress!</p>
<p>It gives you the ability to allow SVG uploads whilst making sure that they’re sanitized to stop SVG/XML vulnerabilities affecting your site.  It also gives you the ability to preview your uploaded SVGs in the media library in all views.</p>
<h4>Current Features</h4>
<ul>
<li><strong>Sanitised SVGs</strong> – Don’t open up security holes in your WordPress site by allowing uploads of unsanitised files.</li>
<li><strong>SVGO Optimisation</strong> – Runs your SVGs through the SVGO tool on upload to save you space. This feature is disabled by default but can be enabled by adding the following code: <code>add_filter( 'safe_svg_optimizer_enabled', '__return_true' );</code></li>
<li><strong>View SVGs in the Media Library</strong> – Gone are the days of guessing which SVG is the correct one, we’ll enable SVG previews in the WordPress media library.</li>
<li><strong>Choose Who Can Upload</strong> – Restrict SVG uploads to certain users on your WordPress site or allow anyone to upload.</li>
</ul>
<p>Initially a proof of concept for <a href="https://core.trac.wordpress.org/ticket/24251" rel="nofollow ugc">#24251</a>.</p>

Safe SVG

Our agency has a talented illustrator who is adept at creating SVGs, particularly with self-contained CSS animations. We would be loading them all manually from the theme folder with no path to easily add new or replace existing SVGs without developer involvement if it weren't for this plugin. We install Safe SVG on pretty much all sites we custom build for our clients.

I'm really hoping for some additional features to come to this plugin to better support the Gutenberg editor, since the core image block doesn't handle SVGs well. But that doesn't affect my 5-star review as the most reliable SVG upload plugin.

Agency go-to for SVG uploads

Why Automattic hates SVG has always been a source of confusion to me. Why shouldn't uploading SVG be as easy and straightforward as any other kind of (supported) image? Then again, it's true that you can write malicious code inside a SVG rather easily. The solution? Safe SVG. It cleans up a malformed or malicious SVG during the upload, so that when it arrives in your Media Library, it will already have been sanitised.

The plugin is as simple to operate as it is useful. All parts of WP that require opening the Media Library browser will now accept SVGs as well. As others have remarked, there are some outstanding issues when previewing SVGs inside Gutenberg. No surprises there — this plugin has predated Gutenberg, and (at the time of writing) has been abandoned for about two years, during which Automattic has been eagerly upgrading WordPress.

The author has not gone away, though. He is still actively developing the sanitising part of the plugin, using a library he has developed and posted on GitHub, and which has accepted several contributions and gone through many code reviews. It's possibly the reference library for SVG sanitation written in PHP.

And fortunately he's now back and has released a brand new version as of late February 2022 :)

Incredibly useful!

Great plugin, does what it says. Should be core functionality.

Why is this not a part of core?


Great plugin! very usefull, but please can you add the possibility to add an inline SVG on the block pasting svg code?



Thanks!


Wonderful + fetaure request

Enable SVG uploads and sanitize them to stop XML/SVG vulnerabilities in your WordPress website.
