Tempaloo

<p><strong>The pricing problem with most WebP plugins</strong></p>
<p>WordPress generates 5-8 thumbnails for every image you upload (<code>thumbnail</code>, <code>medium</code>, <code>medium_large</code>, <code>large</code>, <code>full</code>, plus theme-specific sizes). Most popular optimizers count each thumbnail as a separate credit, so a single product photo or blog hero can burn through 6-8 credits before you’ve touched your second image.</p>
<p>Tempaloo charges <strong>1 credit per upload</strong>, no matter how many sizes WordPress derives from it. Same quota, 6-8x more usable conversions.</p>
<p><strong>Concrete comparison — 1,000 uploads / month</strong></p>
<ul>
<li>ShortPixel / Imagify (per-thumbnail billing): <strong>6,000 to 8,000 credits consumed</strong> <span aria-hidden="true" class="wp-exclude-emoji">→</span> you need a 10k or 20k plan.</li>
<li>Tempaloo (per-upload billing): <strong>1,000 credits consumed</strong> <span aria-hidden="true" class="wp-exclude-emoji">→</span> our 5,000-image Starter plan covers you 5x over.</li>
</ul>
<p>If your site averages 4+ thumbnails per upload (which it does, by default), Tempaloo is the lowest cost-per-converted-image on the market.</p>
<p><strong>Built for</strong></p>
<ul>
<li><strong>Agencies</strong> managing 10–100 client sites tired of credit math and license-per-site upcharges (our Growth plan covers 5 sites; Business covers unlimited).</li>
<li><strong>WooCommerce stores</strong> with 50+ photos per product who blow through ShortPixel quotas in days.</li>
<li><strong>Photographers, portfolios, magazines</strong> who want AVIF + high quality without the Imagify Pro tier.</li>
</ul>
<p><strong>What’s in version 1.0</strong></p>
<ul>
<li><strong>Async upload pipeline</strong> — conversion runs in a fresh PHP process via non-blocking loopback, so your uploads finish instantly and we never fight other plugins on the same WordPress filter chain (security scanners, page builders, other optimizers). Most optimizers convert sync inline; that’s where conflicts come from.</li>
<li><strong>Bulk converter</strong> with adaptive backoff, pause/resume, and live progress (current image, savings counter, ETA).</li>
<li><strong>Diagnostic + reconcile tab</strong> — drift detection across filesystem, attachment metadata, bulk state, and retry queue. One click to repair desynchronized state. Most optimizers leave this to the user; we audit it.</li>
<li><strong>AVIF on every paid tier</strong> — not a Pro-only add-on. Starter (5€/mo) already includes it.</li>
<li><strong>WP-CLI</strong> — <code>wp tempaloo status / activate / bulk / restore / quota</code>. First-class deploy story for managed WordPress hosts.</li>
<li><strong>Picture-tag and URL-rewrite delivery modes</strong> — picture-tag works with Gutenberg, Elementor, Bricks, Divi, Beaver Builder, WooCommerce, and any theme. URL rewrite stays out of your markup. CDN passthrough also supported.</li>
<li><strong>Compatibility hardening</strong> — atomic temp+rename writes, explicit <code>nocache_headers()</code> + <code>DONOTCACHEPAGE</code> so LiteSpeed Cache, WP Rocket, and W3 Total Cache never serve stale admin data.</li>
<li><strong>Developer hooks</strong> — three filters/actions to skip attachments, override quality, and react after conversion. See “Developer hooks” below.</li>
</ul>
<p><strong>Pricing</strong></p>
<ul>
<li><strong>Free plan</strong>: 250 images / month, 1 site, no credit card required.</li>
<li><strong>Starter</strong> (5 €/mo): 5,000 images/month, AVIF included.</li>
<li><strong>Growth</strong> (12 €/mo): 25,000 images/month, 5 sites per license.</li>
<li><strong>Business</strong> (29 €/mo): 150,000 images/month, unlimited sites.</li>
<li><strong>Unlimited</strong> (59 €/mo): fair-use 500k/mo, priority SLA.</li>
</ul>
<p>Paid plans include a 7-day trial and a 30-day money-back guarantee. Credits roll over up to 30 days on paid plans.</p>

<h3>Privacy</h3>
<p>See the <strong>External services</strong> section above for a full disclosure of the data this plugin sends to the Tempaloo API.</p>
<h3>Developer hooks</h3>
<p>Three hooks let you tailor the plugin’s behavior from your own theme or custom plugin. They fire on both the auto-convert-on-upload path and the bulk path (CLI or admin), so a single rule applies everywhere.</p>
<pre><code>apply_filters( 'tempaloo_webp_skip_attachment', false, $attachment_id, $mode )
</code></pre>
<p>Return <code>true</code> to bypass conversion for a specific attachment. Useful to exclude a folder, a CPT, or images larger than a threshold.</p>
<pre><code>apply_filters( 'tempaloo_webp_quality_for', $quality, $attachment_id, $format )
</code></pre>
<p>Override the quality value (1–100) per attachment. Returned values are clamped to 1–100. Useful to lift quality on portfolio shots or drop it on product thumbnails.</p>
<pre><code>do_action( 'tempaloo_webp_after_convert', $attachment_id, $info )
</code></pre>
<p>Fired after a successful conversion (one or more sizes written). <code>$info</code> contains <code>format</code>, <code>converted</code>, <code>failed</code>, <code>mode</code>, <code>quality</code>, <code>sizes</code>. Useful for CDN purges, custom logging, webhooks, manifest rebuilds.</p>
<p>Example — skip conversion for any attachment in the <code>private/</code> upload subfolder:</p>
<pre><code>add_filter( 'tempaloo_webp_skip_attachment', function( $skip, $id ) {
    $path = get_attached_file( $id );
    return $path && false !== strpos( $path, '/uploads/private/' );
}, 10, 2 );<h3>Source code</h3>
</code></pre>
<p>Tempaloo WebP is open source under the GPLv2 (or later) license. All compiled assets are generated from human-readable sources included in this distribution — no obfuscated or auto-generated code without a matching source.</p>
<h4>Compiled assets</h4>
<p>The admin dashboard UI is built with Vite + React + TailwindCSS. The compiled output (<code>build/admin.js</code> and <code>build/admin.css</code>) is generated from the source files under <code>admin-app/</code>:</p>
<ul>
<li>TypeScript / TSX source: <code>admin-app/src/</code></li>
<li>Build configuration: <code>admin-app/vite.config.ts</code>, <code>admin-app/tsconfig.json</code>, <code>admin-app/tailwind.config.js</code>, <code>admin-app/postcss.config.js</code></li>
<li>Dependency manifest: <code>admin-app/package.json</code> (and <code>admin-app/package-lock.json</code> for reproducible installs)</li>
</ul>
<h4>How to rebuild</h4>
<p>From the plugin root:</p>
<pre><code>cd admin-app
npm install
npm run build
</code></pre>
<p>This regenerates <code>build/admin.js</code> and <code>build/admin.css</code>. Output is deterministic — same source plus same lock file produce the same bytes.</p>
<pre><code>npm run typecheck runs the TypeScript compiler in `--noEmit` mode for a standalone type check.
</code></pre>
<h4>Third-party libraries</h4>
<p>All third-party libraries are pulled in via npm (declared in <code>admin-app/package.json</code>) — none are vendored as pre-built minified files in this repository. Their licenses are MIT and compatible with GPLv2-or-later.</p>

Tempaloo WebP

The image optimizer that doesn't charge you for thumbnails. 1 credit per upload, all sizes included — 6-8x more conversions for the same quota.

CompressX

<p>CompressX is a free, lightweight WebP & AVIF conversion and media replacement plugin for WordPress. It allows you to easily convert JPG and PNG images to WebP and AVIF formats, compress WebP and AVIF images, and replace media files without changing their URLs or attachment IDs. All AVIF and WebP conversions are performed locally on your web server.</p>
<h3>Core Features</h3>
<h4>1. Convert AVIF & Compress AVIF</h4>
<p>Convert jpg, png, and WebP images on your WordPress website to AVIF format, and compress AVIF images according to the compression level you set.<br />
If the original image is already in AVIF format which is supported since WordPress 6.5, the original AVIF image will only be compressed.</p>
<h4>2. Convert WebP & Compress WebP</h4>
<p>Convert jpg, png images on your WordPress website to WebP format, and compress WebP images according to the compression level you set.<br />
If the original image is already in WebP format which is supported since WordPress 5.8, the original WebP image will only be compressed.</p>
<h4>3. Media Replacement & Auto Re-Optimization</h4>
<p>Safely replace an existing media file without changing its URL or attachment ID. When a new image is uploaded as a replacement, the system automatically regenerates thumbnails, applies your configured format conversion and compression rules, resizes where needed, and re-optimizes the file.</p>
<h4>4. Exclude Folders</h4>
<p>Select specific folders in your media library and prevent images inside them from being processed.</p>
<h4>5. Custom Folders</h4>
<p>Select folders that are in the wp-content folder but outside the Uploads (media library) and process images inside them.</p>
<h4>6. Auto-Process New Images</h4>
<p>Automatically convert new images uploaded to a WordPress website to WebP/AVIF format and compress WebP/AVIF images upon upload.</p>
<h4>7. Auto-Remove Large Images</h4>
<p>Automatically remove converted AVIF/WebP images when they are larger than original images.</p>
<h4>8. Restore Original Images</h4>
<p>Your images will be reverted to their original state and all AVIF/WebP images and data in the database generated by CompressX will be removed when CompressX is uninstalled.</p>
<h3>Minimum Requirements to use CompressX</h3>
<ul>
<li>Character Encoding UTF-8</li>
<li>PHP version 7.0</li>
<li>MySQL version 4.1</li>
<li>WordPress 5.8</li>
</ul>
<h3>External Services</h3>

CompressX — AVIF & WebP Converter, Media Replacement


It's all new, but I believe this can go far ! I was looking for a plugin with free AVIF conversion, and locally hosted (a lot of images plugins use their servers to compress, that's why a lot of them are expensive).Awesome support, totally free (for now ?), does the same thing as the famous Media Converter, but with free AVIF. Take my 5/5 rating ;)EDIT : Oh no wait, it does more than media converter, allowing you to set a max width / height on your images :fire:


This may be my future goto plugin for image optimisation


Deserves 5-stars just for vision and generosity in making this exist!



Will give it a thorough test and post any feedback as we go.



Thank you 🙏


The world thanks you!
