HostSalt Image Optimizer connects your WordPress site to the HostSalt IO cloud API to automatically compress and convert images on upload. No server-side libraries required — just install, connect and start saving bandwidth.
Features:
<ul>
<li>Automatic optimization on upload — no manual steps needed</li>
<li>Converts images to WebP or AVIF for maximum compression</li>
<li>Smart format selection — picks whichever format saves more</li>
<li>Lossless backup — restore originals any time with one click</li>
<li>Bulk optimize your entire existing media library</li>
<li>Bulk restore all images to their originals</li>

</ul>
How it works:
When you upload an image, HostSalt Image Optimizer sends it securely to the HostSalt IO API. The API compresses and converts the image, then returns the optimized version. The original is kept as a backup so you can restore at any time.
A free plan is available with 50 optimizations per month. Paid plans are available for higher volumes.
<h3>External Services</h3>

<li>Data received: optimized image file</li>

WordPress image management is a mess. And most site owners don’t even know it.
Here’s what’s quietly happening on your site right now:
<ul>
<li>Each upload creates 7+ thumbnails. Themes and plugins add more. Most stay unused and waste storage.</li>
<li>Many images are still JPG or PNG. They’re heavier, slow down pages, and hurt Core Web Vitals and rankings.</li>
<li>Unused, duplicate, and oversized images keep piling up. Updating them across pages takes extra time.</li>
</ul>
None of this is dramatic. It’s just the slow, invisible damage that builds up on every WordPress site without a proper image management system.
ThumbPress fixes it all with a single plugin.
ThumbPress is a complete WordPress image optimization and media management plugin built for site owners, developers, and agencies who want full control over their media library. Compress images, convert to WebP or AVIF, regenerate thumbnails, find duplicate images, detect unused files, and much more — all from your WordPress dashboard.
Version 6.0 is here – with a redesigned interface, AVIF image conversion, and duplicate image detection.

🚀 Free Features – In Detail
Disable Thumbnails – Stop Wasting Server Storage
Every image upload triggers WordPress to create multiple resized copies – Thumbnail, Medium, Medium-Large, Large, Scaled — plus whatever your theme and plugins add on top. Most of these copies are never used anywhere on your site.
The Disable Thumbnails module lets you choose exactly which image sizes to block. Stop the copies before they’re created, save server storage from day one, and keep your WordPress media library clean and manageable.
Regenerate Thumbnails – Fix Broken Image Sizes Instantly
Switched themes? Changed your image size settings? Installed a new page builder? Your existing images now have the wrong dimensions – and broken layouts are the result.
The Regenerate Thumbnails module rebuilds all your image sizes on demand. Select specific sizes or regenerate everything at once. No manual work, no missing thumbnails. Your site stays consistent without touching a single image file.
Convert Images to WebP – Boost Site Speed and SEO Rankings
WebP images are 25–35% smaller than JPG and PNG without any visible quality loss. Google recommends WebP. Core Web Vitals reward it. Page speed tools flag JPG and PNG as a performance issue.
ThumbPress converts your existing WordPress images to WebP in bulk or one by one, right from your dashboard. No FTP, no separate tools. Just faster images and better SEO rankings.
Convert Images to AVIF – Next-Generation Image Format
AVIF is the successor to WebP. It compresses images even further while preserving quality, and browser support is now mainstream across Chrome, Firefox, and Safari.
ThumbPress lets you convert individual images to AVIF for free. Need to convert your entire media library at once? That’s a Pro feature available in the new 6.0 release.
Image Upload Limit – Protect Site Performance at the Source
One oversized image upload can slow down a page significantly. Without limits, editors and contributors regularly upload images straight from their phones or cameras – files that are 5MB, 10MB, sometimes larger.
Set a maximum file size and resolution for every image upload. Any file that exceeds your rules gets blocked before it ever hits the server. Clean media library, faster site – automatically enforced.
Social Media Thumbnails – Look Intentional Everywhere You’re Shared
When you share a page on Facebook, Twitter, or LinkedIn, each platform crops the image differently. Without customization, your carefully chosen image ends up poorly framed or cut off entirely.
ThumbPress lets you set distinct thumbnails for each social media platform. Upload one version for Facebook, another for Twitter, another for LinkedIn. Your content always looks deliberate when shared.
Lazy Load Images – Faster Pages Without Changing a Single Image
By default, WordPress loads every image on a page at once – including images that are way below the fold and won’t be seen until the user scrolls down. That’s wasted bandwidth, slower initial load times, and a worse experience for users on mobile or slower connections.
Lazy loading changes this. Images only load as users scroll toward them. The result is a noticeably faster page on first load, lower bandwidth usage, and a real improvement in Core Web Vitals scores – all without touching your images or content.
Hotlink Protection – Stop Other Sites From Stealing Your Bandwidth
Hotlinking happens when another website embeds your images directly using your image URLs. Your server serves the image, your bandwidth takes the hit – and you get nothing in return.
ThumbPress blocks external sites from loading images directly from your server. Your images stay on your site, your bandwidth stays yours, and your hosting costs don’t quietly inflate because someone else decided to use your media library as their CDN.
Disable Right Click – Protect Your Images from Theft
Right-click protection disables the ability to save, copy, or drag images directly from your site. It’s a practical barrier that stops casual image theft – especially useful for photographers, portfolio sites, and ecommerce stores.
Enable it globally or for specific pages. No code needed.
🔥 Pro Features — In Detail
Find and Delete Unused Images — Reclaim Your Server Space
As websites evolve, images get left behind. Old blog post headers, replaced product photos, outdated banners — they all stay in your media library indefinitely, taking up space and adding noise.
The Find Unused Images module scans your entire site and surfaces every image that isn’t linked to any post, page, or content. Review the list, then delete in bulk. Reclaim storage and clean up years of media clutter in minutes.
Detect Large Images — Find What’s Slowing Your Site Down
Large images are one of the top causes of slow WordPress page load times. And slow pages hurt conversions and search rankings alike.
ThumbPress scans your media library for oversized images and flags them for action. Then compress them directly from the dashboard — no image editing software, no re-uploading. A faster WordPress site without sacrificing visual quality.
Image Compression — Smaller Files, Same Visual Quality
ThumbPress includes a built-in WordPress image compression tool that reduces file size while keeping your images sharp. Compress in bulk across your entire media library or optimize new uploads automatically.
Smaller images mean faster pages, better Core Web Vitals scores, and stronger SEO — across your entire site.
Replace Image with New Version — Update Without Breaking Links
Need to update a product image, fix a low-quality photo, or refresh a visual after a rebrand? Normally, replacing an image in WordPress means deleting the old file and updating every page where it appears manually.
ThumbPress lets you replace an image with a newer version while keeping the same URL. Every page, post, or widget that uses that image updates automatically. No broken links. No manual edits.
Detect Duplicate Images — New in 6.0 🆕
Duplicate images waste storage and create confusion in your media library. The same file uploaded twice, variations of the same photo, slightly different crops of one original — they all add up over time.
The new Duplicate Image Detection module identifies redundant files in your media library and helps you remove them safely. One of the most-requested features we’ve ever received — now available in ThumbPress 6.0.
Image Editor — Edit Images Without Leaving WordPress
Sometimes an uploaded image just needs a small adjustment — a crop, a rotation, a brightness tweak. The ThumbPress Image Editor lets you make those changes without ever leaving your WordPress dashboard.
No Photoshop. No re-uploading. Edit, save, and publish right from your media library.
🆕 What’s New in ThumbPress 6.0
<ul>
<li>Redesigned interface — cleaner, faster, and easier to navigate</li>
<li>AVIF Image Converter — next-gen format support, with bulk conversion via Pro</li>
<li>Duplicate Image Detection — find and remove redundant files from your media library</li>
<li>Improved performance across all existing modules</li>
</ul>
👉 Why ThumbPress Instead of Multiple Separate Plugins?
Most WordPress sites end up using 4–6 different plugins just to manage images:
<ul>
<li>One for thumbnail control</li>
<li>One for compression</li>
<li>One for WebP conversion</li>
<li>One for social media previews</li>
<li>One for image cleanup</li>
</ul>
Each plugin adds overhead. Each one adds potential conflicts. And none of them talks to each other.
ThumbPress is one plugin that does everything. Thumbnail management, image compression, WebP and AVIF conversion, media library cleanup, duplicate detection, image protection — all in a single, unified interface. Install once, manage everything.
