Bulk compression allows you to compress multiple photos simultaneously, speeding up optimization.&nbsp;<\/p>\n\n\n\n<p>Image compression has one mission: <a href=\"https:\/\/imagify.io\/blog\/reduce-image-size-without-losing-quality\/\">reduce file sizes to the maximum while preserving quality<\/a>. The ultimate goal is to serve optimized images that look great and do not slow down your site.&nbsp;<\/p>\n\n\n\n<p>If your site has only a few images, you could compress them manually one by one; that\u2019s true. But what if you have a site with 200 images?<\/p>\n\n\n\n<p>&nbsp;In that case, bulk compression will be your best ally!<\/p>\n\n\n\n<p>This guide provides the best tools to compress your images in bulk according to your needs. We also include data, stats, and performance tests for each tool to help you make an informed decision.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How to Compress Images in Bulk<\/h2>\n\n\n\n<p>To compress images in bulk, you&#8217;ll need to use a WordPress plugin like Imagify, an online platform tool, or a design software such as Photoshop. Before listing the best type of tools you can use, it\u2019s essential to define your needs and understand the different steps of image optimizations.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">1. Do A Backup<\/h3>\n\n\n\n<p>We recommend you do a backup before compressing images for two main reasons:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Easy recovery<\/strong>: if the compression goes wrong, you must be able to restore your original photos quickly. Compression can sometimes result in unexpected quality loss, so having backups allows you to compare and ensure the compressed images meet your standards.<\/li>\n\n\n\n<li><strong>To be on the safe side<\/strong>: backups ensure you don&#8217;t lose any important images in case of technical issues or errors during the compression process.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">2. Define Your Needs<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Skill level<\/strong>: how comfortable are you with manual compression? Can you use Photoshop or do you prefer a tool that works directly with WordPress?<\/li>\n\n\n\n<li><strong>Compression requirement<\/strong>: how much compression do your images need? If you are a photographer, you may want lossless compression. However, you should optimize more if you have a big e-commerce store.&nbsp;<\/li>\n\n\n\n<li><strong>Budget and image optimization volume<\/strong>: how much are you willing to spend? How many photos do you have to optimize?&nbsp;<\/li>\n\n\n\n<li><strong>Image format<\/strong>: are your images in JPEG, PNG, WebP, or AVIF? Do you need to convert them to save even more data? Google recommends using next-gen formats like WebP and AVIF for better compression. If you&#8217;re using traditional formats, it may be time to convert them.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Choose the Right Image Format<\/h3>\n\n\n\n<p>Google recommends using next-gen formats like WebP and AVIF because they offer better compression than traditional formats. Converting to these formats can significantly reduce file sizes while maintaining quality.&nbsp;<\/p>\n\n\n\n<p>According to Google, the average <a href=\"https:\/\/developers.google.com\/speed\/webp\/gallery1\">WebP file size is 25% to 34% smaller<\/a> than the JPEG file size, which is of similar quality.\u00a0<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"555\" src=\"https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/WebP-has-superior-compression-levels-source-Google-WebP-.png\" alt=\"WebP has superior compression levels than JPEG - Source: Google WebP\n\" class=\"wp-image-2556\" srcset=\"https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/WebP-has-superior-compression-levels-source-Google-WebP-.png 800w, https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/WebP-has-superior-compression-levels-source-Google-WebP--300x208.png 300w, https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/WebP-has-superior-compression-levels-source-Google-WebP--768x533.png 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">WebP has superior compression levels than JPEG &#8211; Source: <a href=\"https:\/\/developers.google.com\/speed\/webp\/gallery1\">Google WebP<\/a><br><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">4. Choose the Right Compression Level and Type<\/h3>\n\n\n\n<p>Generally, image optimization has two types of compression: lossy and lossless.&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Lossy compression<\/strong>: it reduces file size significantly but with some quality loss. Suitable for general web use where slight quality loss is acceptable.<\/li>\n\n\n\n<li><strong>Lossless compression<\/strong>: it preserves original quality but with less reduction in file size. It is ideal for photographers or situations where image quality is critical.<\/li>\n<\/ul>\n\n\n\n<p>If you focus on web performance, lossy compression is your best bet. Lossy does not mean a blurry image; the compression is usually not noticeable to the naked eye. Some tools automatically balance quality and file size while applying lossy compression on your images. For example, Imagify offers a feature named &#8220;<a href=\"https:\/\/imagify.io\/blog\/imagify-smart-compression\/\">Smart compression<\/a>,&#8221;.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td>\ud83d\udcd6 Learn more about <a href=\"https:\/\/imagify.io\/blog\/lossless-vs-lossy-image-compression\/\">lossy vs lossless compression<\/a> in our dedicated article.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>Your final choice will depend on the level of compression you need. For instance, if you are a photographer, you may need lossless compression to maintain image quality. However, if web performance is essential to you, then loss compression will be better for saving bytes.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Resize Images<\/h3>\n\n\n\n<p>To bulk-reduce image size and improve your site performance, you can use the following tools:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Imagify<\/strong> (WordPress Plugin): it lets you set a maximum size for your images.<\/li>\n<\/ul>\n\n\n\n<p>Go to <strong>Settings<\/strong> &gt; <strong>Imagify<\/strong> &gt; Check the box next to <strong>Resize larger images.&nbsp;<\/strong><\/p>\n\n\n\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/lh7-rt.googleusercontent.com\/docsz\/AD_4nXeNZ6N4w2o-qnJn3UjDVl0JdyBsHSaW6JpCuGPnr32G_L5s50T1dp95PzEAJxr-xVk-PcQnWqMmr19KVP2YKviXftcVcsPWDzWO9R3u72jtMAOFH9lwjbwebbOBRrUMFU1Xv4LY0f0B4BCvsh_yEN_1ML8?key=KRDsu6VmMKEstCXneObU1w\" width=\"602\" height=\"312\"><br>Resizing larger images with Imagify &#8211; Source: The Imagify plugin<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Preview<\/strong>: A native Mac application for bulk image resizing.<\/li>\n<\/ul>\n\n\n\n<p>Open all your images at once, select them all, and go to <strong>Tools<\/strong> &gt; <strong>Adjust size.<\/strong>\u00a0<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"690\" src=\"https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/How-to-resize-images-in-bulk-Source-Preview-.png\" alt=\"\" class=\"wp-image-2557\" srcset=\"https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/How-to-resize-images-in-bulk-Source-Preview-.png 800w, https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/How-to-resize-images-in-bulk-Source-Preview--300x259.png 300w, https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/How-to-resize-images-in-bulk-Source-Preview--768x662.png 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">How to resize images in bulk &#8211; Source: Preview<br><\/figcaption><\/figure>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Photos:<\/strong> A Windows application for bulk image resizing.<\/li>\n<\/ul>\n\n\n\n<p>Now that you know more about image compression, let\u2019s review the tools to compress images in bulk.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Choose the Right Compression Tool for Your Needs (+ Performance Tests)<\/h3>\n\n\n\n<p>There are three categories of tools to bulk compress images according to your specific needs:&nbsp;<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>WordPress plugins<\/strong>: they automate bulk image compression directly from your WordPress dashboard.<\/li>\n\n\n\n<li><strong>Online tools<\/strong>: they compress images in bulk through user-friendly web interfaces.<\/li>\n\n\n\n<li><strong>Design software<\/strong>: they provide advanced features for precise compression and resizing.<\/li>\n<\/ol>\n\n\n\n<h3 class=\"wp-block-heading\">Use a WordPress Plugin to Compress Images in Bulk<\/h3>\n\n\n\n<p>An image compression WordPress plugin is a tool that reduces the file size of images directly on your WordPress site to improve loading times and performance.<\/p>\n\n\n\n<p><strong>Examples<\/strong>: <a href=\"https:\/\/imagify.io\/wordpress\/\">Imagify<\/a> or <a href=\"https:\/\/wordpress.org\/plugins\/tiny-compress-images\/\">TinyPNG<\/a>.<\/p>\n\n\n\n<p>The two plugins work similarly: you need to check a few options and click on a button to start the bulk compression. Note that some also offer automatic compression when you upload the image (on the fly), so you don\u2019t need to do anything.&nbsp;<\/p>\n\n\n\n<p>To give you an overview of how these plugins work, here is a short tutorial with Imagify:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Go to <strong>Media<\/strong> &gt; <strong>Bulk Optimization <\/strong>and click the<strong> Imagify\u2019em all<\/strong> button.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"370\" src=\"https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/Bulk-Optimization-with-Imagify-Source-Imagify.png\" alt=\"Bulk Optimization with Imagify - Source: Imagify\n\" class=\"wp-image-2558\" srcset=\"https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/Bulk-Optimization-with-Imagify-Source-Imagify.png 800w, https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/Bulk-Optimization-with-Imagify-Source-Imagify-300x139.png 300w, https:\/\/imagify.io\/blog\/wp-content\/uploads\/2024\/07\/Bulk-Optimization-with-Imagify-Source-Imagify-768x355.png 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">Bulk Optimization with Imagify &#8211; Source: <a href=\"https:\/\/imagify.io\/\">Imagify<\/a><\/figcaption><\/figure>\n\n\n\n<p>That\u2019s it!
