Enable SVG


This plugin serves one simple purpose: to add support for uploading SVG files in the WordPress Media Library.

WordPress 4.7 introduced changes to the file validation process for images. While this generally makes image uploads more secure, it breaks existing plugins that made SVG uploads available.

This is because the SVG format uses the MIME type “image/svg+xml”, and WordPress 4.7 uses a pair of core PHP functions for validating any file that has an “image/” MIME type, but those functions don’t handle SVG.

This plugin detects whether the uploaded file is an SVG and, if so, replaces the new WordPress image validation with checks that 1) the uploaded file is valid XML, and 2) it contains certain required text strings expected in an SVG file. Please note: For performance reasons, this is not a strict SVG validator, and does not provide complete protection from possible SVG security exploits.

Do not use this plugin if you are concerned about SVG as a possible security risk. This plugin is provided as-is with no warranty whatsoever.

thanks a lot, this works! the plugin itself limits itself to the backend and is as light as possible.
