<p><strong>MITS Image Optimizer</strong> is a professional image optimization toolkit for WordPress. It compresses images automatically on upload, batch-converts your entire media library to WebP and AVIF, configures Apache to serve next-gen formats automatically, and scans your site for common technical SEO issues.</p>
<h4>Features</h4>
<p><strong>Auto-Compress on Upload</strong><br />
Every JPG/PNG above a configurable size threshold is automatically scaled and compressed before WordPress generates its thumbnail sizes. No extra steps needed.</p>
<p><strong>Bulk Compression</strong><br />
Run a background batch job to compress all existing images in your media library. Progress is tracked and the job runs asynchronously — it won’t block your browser.</p>
<p><strong>WebP Converter</strong><br />
Batch-convert all JPG/PNG/GIF files in your uploads directory to WebP format. Runs in the background using WP-Cron or a loopback HTTP request. Supports both Imagick and GD libraries.</p>
<p><strong>AVIF Converter</strong><br />
Convert images to AVIF — the next-generation format that can be 30–50% smaller than WebP. Requires Imagick 7+ with AVIF support or PHP 8.1+ with GD <code>imageavif()</code>. The plugin detects support automatically and warns you if AVIF is unavailable on your server.</p>
<p><strong>Apache .htaccess Configuration</strong><br />
One click adds <code>mod_rewrite</code> rules to your <code>.htaccess</code> so Apache automatically serves <code>.webp</code> files to browsers that support them, with no code changes required in your theme.</p>
<p><strong>Image Dimensions Scanner</strong><br />
Detects images ≥ 1600 px wide that are used in posts or as featured images. Helps you find oversized images that slow down page loads, along with their file sizes, dimensions, and WebP/AVIF conversion status.</p>
<p><strong>Site Audit</strong><br />
Scans your site for the most common technical issues: missing alt text, oversized images, missing SSL, outdated plugins, pages without Open Graph tags, and more. Results include actionable recommendations.</p>
<p><strong>Dashboard Widget</strong><br />
A compact stats panel on the WordPress admin dashboard showing compression savings, WebP/AVIF conversion counts, and a link to the optimizer.</p>
<h4>Requirements</h4>
<ul>
<li>PHP 8.0+, WordPress 6.0+</li>
<li>GD or Imagick PHP extension (for WebP/compression)</li>
<li>Imagick 7+ with AVIF or PHP 8.1+ GD (for AVIF conversion)</li>
<li>Apache + <code>mod_rewrite</code> (for automatic WebP serving via <code>.htaccess</code>)</li>
</ul>

<p>Tired of resizing, compressing, converting, optimizing and exporting images over and over again? Better Images is a plugin that automagically does this hard work for you. Just upload your image into the media library and the plugin will produce an image that is both better looking and smaller in size. And it will also resize the original full resolution image to save space.</p>
<p>If you benefit from this plugin please consider <a href="https://wordpress.org/support/plugin/better-images/reviews/#new-post" rel="ugc">writing a review</a>! That would mean a lot to us.</p>
<p><strong>Disclaimer:</strong> With this plugin activated you can’t regenerate images via other plugins or WP-CLI. Regeneration will be available in a upcoming Pro-version.</p>
<h3>Here’s everything that Better Images will do for you every time you upload an image:</h3>
<ul>
<li>Resizes and compresses the original full resolution image</li>
<li>Sharpens the image to make it more appealing and crisp</li>
<li>Removes EXIF data but keeps color space profile</li>
<li>Converts from PNG to JPG</li>
<li>Converts from CMYK to RGB</li>
<li>Checks if the image already exist to avoid duplicates</li>
<li>Replaces special characters and non english letters in the filename</li>
<li>Adds a max height of 768 pixels to medium_large size variant</li>
</ul>
<p>And one bonus feature: It displays all image sizes in the editing screen.</p>
<h3>And here’s the nitty-gritty of what is actually happening in the background:</h3>
<h3>Resizes and compresses the original full resolution image</h3>
<p>In version 5.3 WordPress introduced handling of big images. The solution that was implemented is to create a new size variant of 2560 pixels with the addition of the word “scaled” in the filename. This variant serves as the new full size image on the website. The real original full size image though is not deleted but kept on the server in case one would want to resize to a different size or regenerate thumbnails. This image is never used on the website however and resizing images to pixel perfect sizes is a thing of the past due to the advent of responsive image handling.</p>
<p>What Better Images does is resizing the original full size image to the maximum size of 2560 pixels replacing the default scaled variant. In the process we also get rid of the word “scaled” in the filename.</p>
<h3>Sharpens the image to make it more appealing and crisp</h3>
<p>Every time we resize an image it becomes blurry. Apps like Photoshop, Pixelmator, Affinity Photo and the like will compensate this by applying som degree of sharpening to make images look better. WordPress does not do that and that’s why we end up with blurry images.</p>
<p>However Better Images does that for you. We have tweaked the sharpening level to avoid over sharpening artifacts. The plugin applies the perfect amount of sharpening to make your images pop and look at their best.</p>
<h3>Removes EXIF data but keeps color space profile</h3>
<p>Almost all images taken with a camera or downloaded from a stock photo library has EXIF data embedded in them. EXIF data is information about shutter speed, exposure compensation, aperture speed, what metering system, if a flash was used, ISO number, date and time the image was taken, white balance, GPS coordinates and so on. This data is in the majority of time not used or needed on a website. Therefore we remove the EXIF data and shave off up to 30 kb from the file size.</p>
<p>Removing the EXIF data however also removes the color space profile which will result in an image that looks different form the original. Since we wouldn’t want that we leave the color space profile untouched.</p>
<h3>Converts from PNG to JPG</h3>
<p>The file format PNG (Portable Network Graphics) is a popular image format because of its non destructive nature. However it is not at all suitable for photographs that will be used on a website due to its heavy size. In contrast a JPG image can be up to 20 times lighter in file size.</p>
<p>Better Images can convert uploaded PNG image to JPG for you. This will not only save you a lot of disk space, but also make your website load much faster.</p>
<h3>Converts from CMYK to RGB</h3>
<p>Sometimes you will get an image that’s exported to be used in print and therefore it uses the CMYK color mode. WordPress is not that great at handling this so it will create multiple variants of the image in different sizes, each of them weighing in at the same size in mega byte as the original full size image. That’s crazy!</p>
<p>Better Images solves this by converting the image to RGB mode before any resizing or compression occurs.</p>
<h3>Checks if the image already exist to avoid duplicates</h3>
<p>One of the things that will take unnecessary space from your server is uploading the same image multiple times. Often times we forget that we already uploaded the image once before, so we upload it again. WordPress by default won’t warn you that you are about to upload a duplicate image. Instead it puts a number in the filename and lets the image pass.</p>
<p>With Better Images every time you upload a file it will search the database to see if the image already exist and give you a message to make you aware of that and help you avoid uploading duplicates of the same image.</p>
<h3>Replaces special characters and non english letters in the filename</h3>
<p>WordPress will allow you to upload images with special characters and non english letters in the filename. Everything will work properly. Until that is you decide to move your website or restore it from a backup. Suddenly all image links with special characters and non english letters will break and you will have to reassign these images in all pages and posts manually.</p>
<p>To protect you from that Better Images will clean up and replace all special characters and non english letters in the filename for you.</p>
<h3>Adds a max height of 768 pixels to medium_large size variant.</h3>
<p>The 768 pixel size variant, also called medium_large, was added into WordPress back in the days when responsive image handling where just introduced. The idea was to have an image size that covers mobile phones. The size is not visible in the Media settings panel and it’s the only size variant that does not have any hight limit. That means in practice this size can be larger than the 1024 pixel size if the image is very tall. Since those days a lot has happened and we think that medium_large also should have a height limit just as all other size variants, so we added this feature.</p>
<h3>Displays all image sizes in the editing screen</h3>
<p>By default WordPress will only display and let you choose from four sizes in the editing screen.<br />
– Thumbnail (max 150px square)<br />
– Medium (max 300px width and height)<br />
– Large (max 1024px width and height)<br />
– Full (full/original image)</p>
<p>WordPress however creates four more sizes but does not display them.<br />
– Max 768px width<br />
– Max 1536px width and height<br />
– Max 2048px width and height<br />
– Max 2560px width and height</p>
<p>Better Images will display and let you choose from all these sizes. This is also compatible with many page builders such as Oxygen, Beaver Builder, Divi, Elementor, Brizy and many more.</p>
<h3>You are in control</h3>
<p>All features are enabled by default and most of them can be disabled when needed. Let say for example you are doing a downloads page with press images and want to have full sized images in CMYK mode. No problem, just turn off the setting for CMYK conversion and full resolution image resizing.</p>
