Safe SVG

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.

Free Features

Installation

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

FAQ

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;
} );

WP should incorporate this plugin asap. SVG support is now common everywhere and we still have to rely on a plugin that is no longer maintained and is clearly the best IMHO.

Just loved the plugin. Used it on a couple of website. Never failed me. Thanks to the developers who did a wonderful job.

So i've been using this for while since i switched to using a lot of svg's on my websites but iv noticed that although it allows svg's to be uploaded to the library but when i export & import my divi theme and builder page layout on to different domains or subdomains then the SVG's don't even get uploaded onto th library even when the layout gets exported and imported- this means only png's and jpg's are get uploaded leaving behind the SVG which makes me think if they were ever exported into the layout to start with. So the logic i followed whilst testing this was pretty straight forwards . i had the plugin enabled at all times whilst exporting the layout and then first thing i did was enable it on the other website before importing the divi library layout or even the divi page export layout for that matter. This issue only exists when importing & exporting layouts between different domains and never within the same domain itself. This really left me in a fix and i experienced hours of frustration finding my svg's and uploading them separately into the new website and then relinking them with the new url's. Any help and suggestions are much appreciated. I wrote to ET about this as well but they replied that since the function of SVG is controlled by the Safe svg plugin id just have to raise this issue with you. Also if the developer can be kind enough to let me know if the free version allows for inline Gutenberg block builder usage of the svg or if this issue that i'm having is because im using this free version of this plugin. UPDATED - SOLVED - 30 MINS LATER- I can now officially confirm that iv received the green signal from Divi support itself that this is a Divi problem and they're trying to fix it. So sorry if i caused any inconvenience but please delte this review as im not getting any option to do so. Although iv converted my review to a five star so it doesnt really affect the credibility of this wonderful plugin.

Great little plugin, ideal for displaying SVG brand logo images as part of a logo wall. Seems to work fine with Divi and WP 5.6. Thanks developers!

This plugin adds SVG support to WordPress in the most natural way. No configuration needed – simply upload and use SVG graphics as you would upload and use JPEG, PNG and GIF images.
