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>External services</h3>
<p>This plugin connects to the Tempaloo conversion API hosted at <code>https://api.tempaloo.com</code> to:</p>
<ul>

<li>Fetch your current monthly quota.</li>
<li>Receive webhooks from Freemius (our payment processor) for subscription events.</li>
</ul>
<p><strong>What data is sent</strong></p>
<ul>
<li>Your license key (required for authentication).</li>
<li>Your site URL (for license-to-site binding).</li>
<li>The image bytes to be converted (streamed, never persisted on our servers — originals stay on your server).</li>
<li>Your WordPress and plugin version (for compatibility diagnostics).</li>
</ul>
<p><strong>Data retention</strong></p>
<ul>
<li>Image data is held in memory only during conversion, then discarded.</li>
<li>Usage logs (count of conversions, byte totals, duration) are stored for billing and analytics, associated with your license.</li>
<li>No personal data beyond what is needed to authenticate your license: your account email (collected at activation or via Google OAuth) and the URL of the WordPress site where the license is active.

<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>
