Safe SVG

by 10up

Description

Safe SVG is the best way to Allow SVG Uploads in WordPress!

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.

Current Features

Sanitised SVGs – Don’t open up security holes in your WordPress site by allowing uploads of unsanitised files.
SVGO Optimisation – 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: add_filter( 'safe_svg_optimizer_enabled', '__return_true' );
View SVGs in the Media Library – Gone are the days of guessing which SVG is the correct one, we’ll enable SVG previews in the WordPress media library.
Choose Who Can Upload – Restrict SVG uploads to certain users on your WordPress site or allow anyone to upload.

Initially a proof of concept for #24251.

SVG Sanitization is done through the following library: https://github.com/darylldoyle/svg-sanitizer.

SVG Optimization is done through the following library: https://github.com/svg/svgo.

Installation

Install through the WordPress directory or download, unzip and upload the files to your /wp-content/plugins/ directory

Can we change the allowed attributes and tags?

Yes, this can be done using the svg_allowed_attributes and svg_allowed_tags filters.
They take one argument that must be returned. See below for examples:

add_filter( 'svg_allowed_attributes', function ( $attributes ) {

    // Do what you want here...

    // This should return an array so add your attributes to
    // to the $attributes array before returning it. E.G.

    $attributes[] = 'target'; // This would allow the target="" attribute.

    return $attributes;
} );


add_filter( 'svg_allowed_tags', function ( $tags ) {

    // Do what you want here...

    // This should return an array so add your tags to
    // to the $tags array before returning it. E.G.

    $tags[] = 'use'; // This would allow the <use> element.

    return $tags;
} );

Nice And Easy

Nice And Easy plugin for using SVG files

Good plugin, but missing ...

By rrvoigt on June 21, 2025

Would have given a 5 star, but it seems support is missing for the taxonomy / terms section (like in categories) upload for SVG images. Keep getting an error that the upload isn't supported. Hopefully this will be fixed in a future update. Will update once this is added. Cheers!

Wonderful + fetaure request

Effortless

Thanks for creating this plugin!

Caused very long loading times in homepage translations (wpml)

By headfalcon on July 31, 2024

I didn't look into it but this plugin caused my homepage in translations to take about 30 seconds to load, instead of 1-2. We use WPML. It was back to normal the moment I deleted the plugin.

Quick and easy!

Does what it says. 👍

Sorry, you are not allowed to upload this file type.

Hello everyone,
the Plugin does not work for me, I refreshed, logged in and out, checked several different svg files but the uploading is still not possible.
After having read so many positive reviews I think I am an exception.
Thanks for any advice!

mandatory plugin

I don't understand why this isn't in core wordpress. Plugin integrates flawlessly into the website and causes no issues.

Does what is says. Quick and easy.
