Reinvent Retina Images

Changed your theme? Added WooCommerce or a page builder? Your old images don’t have the sizes the new design asks for, so pages show squeezed full-size images or blurry, badly cropped ones.

Reinvent Retina Images fixes that in one click.

Fix my images. Checks every image, then makes only the sizes that are missing or out of date. Much faster than rebuilding everything, and it notices sizes whose dimensions changed, not just sizes that are missing.

Runs in the background, never times out. Works in small steps that fit your server’s limits, resumes where it left off, and keeps going after you close the page. Large libraries are fine.

Image sizes, under control. See every size your theme and plugins create, how many images are missing it and how much space it uses. Turn off sizes you don’t need, add your own, and set the big image limit.

Free up space, safely. Finds old sizes nothing uses anymore: sizes from your previous theme, leftovers and old JPEG copies after switching to WebP. Before moving a file we check your posts for it and keep anything still in use.

Files go to a private trash first, so you can restore them in one click.

Sharp on retina screens. Turn on Retina 2× for a size and every image also gets a double-size copy. WordPress adds it to the image’s srcset, so phones and high-density screens load the sharp one and other screens keep the small one.

No extra scripts. Images too small for the double size keep the normal one; we never enlarge (upscale) a photo.

WebP and AVIF thumbnails. Make smaller, faster thumbnails with your server’s own image library. WebP is smaller than JPEG at the default quality.

AVIF can be the smallest at a lower quality (around 60); at the same quality number it can come out bigger than JPEG. Your original uploads are never touched.

• Report of images that couldn’t be processed and why

• Simple and Advanced modes, plus a settings search that understands plain words

• WP-CLI: wp thumbnails-reinvent analyze, fix, regenerate, cleanup

Safe by design

• Never touches your original upload or the edited version of an image.

• Makes sizes from the original image, not the downscaled “-scaled” copy, and respects images you edited in WordPress.

• Never deletes another image’s file, even if its name looks like a thumbnail.

• Removed files go to a private trash that visitors can’t open, and can be restored with their image data.

Tip: keep a recent backup, like with any tool that changes files.

External services

This plugin works on your server. Your images are never uploaded anywhere. The plugin connects to one external service, operated by us:

com), used for four things:

• Settings search. It finds the right setting when you describe what you want in your own words. When you type in the settings search box on the plugin’s admin page, it sends the text you typed, the plugin name and the plugin version. Nothing is sent until you type a search.

• Error reports. They help us fix bugs. They are sent only after you click “I Agree” on the privacy notice in the plugin’s admin page. When the admin page hits an error, it sends the error message, the admin page URL (which includes your site address), your browser’s user agent and the plugin version. Before you agree, errors are only saved in the plugin’s own error log on your site.

• The list of Reinvent WP apps on the Reinvent WP → Dashboard page. When an administrator opens that page, your site downloads the current list at most once a day and keeps a copy. Nothing about your site or you is sent.

• The assistant (the Describe a problem with your site field) on the Reinvent WP → Dashboard page and on this plugin’s page. When you send a question, it is sent with any screenshots or text files you attach to it (of a file, only its newest part, with emails, IP addresses, passwords and keys hidden by your browser first), the last few messages of the conversation and the list of Reinvent WP plugins on your site (whether each is active, inactive or not installed, and its version), so the answer can point to the right plugin and setting. Nothing is stored; the conversation stays in your browser tab. If you send feedback from the assistant’s form, your email, site address and message go to the Reinvent WP team, like the feedback form.
