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. Tempaloo charges **1 credit per upload**, no matter how many sizes WordPress derives from it. Same quota, 6-8x more usable conversions. **Concrete comparison — 1,000 uploads / month** * ShortPixel / Imagify (per-thumbnail billing): **6,000 to 8,000 credits consumed** you need a 10k or 20k plan. * Tempaloo (per-upload billing): **1,000 credits consumed** our 5,000-image Starter plan covers you 5x over. If your site averages 4+ thumbnails per upload (which it does, by default), Tempaloo is the lowest cost-per-converted-image on the market. **Built for** * **Agencies** managing 10–100 client sites tired of credit math and license-per- site upcharges (our Growth plan covers 5 sites; Business covers unlimited). * **WooCommerce stores** with 50+ photos per product who blow through ShortPixel quotas in days. * **Photographers, portfolios, magazines** who want AVIF + high quality without the Imagify Pro tier. **What’s in version 1.0** * **Async upload pipeline** — 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. * **Bulk converter** with adaptive backoff, pause/resume, and live progress (current image, savings counter, ETA). * **Diagnostic + reconcile tab** — 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. * **AVIF on every paid tier** — not a Pro-only add-on. Starter (5€/mo) already includes it. * **WP-CLI** — `wp tempaloo status / activate / bulk / restore / quota`. First- class deploy story for managed WordPress hosts. * **Picture-tag and URL-rewrite delivery modes** — 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. * **Compatibility hardening** — atomic temp+rename writes, explicit `nocache_headers()` + `DONOTCACHEPAGE` so LiteSpeed Cache, WP Rocket, and W3 Total Cache never serve stale admin data. * **Developer hooks** — three filters/actions to skip attachments, override quality, and react after conversion. See “Developer hooks” below. **Pricing** * **Free plan**: 250 images / month, 1 site, no credit card required. * **Starter** (5 €/mo): 5,000 images/month, AVIF included. * **Growth** (12 €/mo): 25,000 images/month, 5 sites per license. * **Business** (29 €/mo): 150,000 images/month, unlimited sites. * **Unlimited** (59 €/mo): fair-use 500k/mo, priority SLA. Paid plans include a 7-day trial and a 30-day money-back guarantee. Credits roll over up to 30 days on paid plans.

Both are necessary for license enforcement and are detailed in our privacy policy at https://tempaloo.com/privacy. **Providers** * Conversion API: **Tempaloo** (hosted in Frankfurt, EU). - [Terms of Service](https://tempaloo.com/terms) - [Privacy Policy](https://tempaloo.com/privacy) * Payment processing (paid plans only, triggered by clicking “Upgrade”): **Freemius, Inc.** - [Freemius Privacy Policy](https://freemius.com/privacy/) - [Freemius Terms](https://freemius.com/terms/) By activating this plugin and entering a license key, you agree to Tempaloo’s Terms and Privacy Policy. ### Privacy See the **External services** section above for a full disclosure of the data this plugin sends to the Tempaloo API. ### Developer hooks 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. ``` apply_filters( 'tempaloo_webp_skip_attachment', false, $attachment_id, $mode ) ``` Return `true` to bypass conversion for a specific attachment. Useful to exclude a folder, a CPT, or images larger than a threshold. ``` apply_filters( 'tempaloo_webp_quality_for', $quality, $attachment_id, $format ) ``` 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. ``` do_action( 'tempaloo_webp_after_convert', $attachment_id, $info ) ``` Fired after a successful conversion (one or more sizes written). `$info` contains` format`, `converted`, `failed`, `mode`, `quality`, `sizes`. Useful for CDN purges, custom logging, webhooks, manifest rebuilds. Example — skip conversion for any attachment in the `private/` upload subfolder: ``` add_filter( 'tempaloo_webp_skip_attachment', function( $skip, $id ) { $path = get_attached_file( $id ); return $path && false !== strpos( $path, '/uploads/private/' ); }, 10, 2 );

Source code

``` 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. #### Compiled assets The admin dashboard UI is built with Vite + React + TailwindCSS. The compiled output(` build/admin.js` and `build/admin.css`) is generated from the source files under ` admin-app/`: * TypeScript / TSX source: `admin-app/src/` * Build configuration: `admin-app/vite.config.ts`, `admin-app/tsconfig.json`, ` admin-app/tailwind.config.js`, `admin-app/postcss.config.js` * Dependency manifest: `admin-app/package.json` (and `admin-app/package-lock.json` for reproducible installs) #### How to rebuild From the plugin root: ``` cd admin-app npm install npm run build ``` This regenerates `build/admin.js` and `build/admin.css`. Output is deterministic— same source plus same lock file produce the same bytes. ``` npm run typecheck runs the TypeScript compiler in `--noEmit` mode for a standalone type check. ``` #### Third-party libraries All third-party libraries are pulled in via npm (declared in `admin-app/package. json`) — none are vendored as pre-built minified files in this repository. Their licenses are MIT and compatible with GPLv2-or-later. * React 18 — https://react.dev (MIT) * React DOM 18 — https://react.dev (MIT) * clsx — https://github.com/lukeed/clsx (MIT) * @freemius/checkout — https://github.com/Freemius/checkout (MIT) * TailwindCSS — https://tailwindcss.com (MIT) * Vite — https://vitejs.dev (MIT) * PostCSS — https://postcss.org (MIT) * Autoprefixer — https://github.com/postcss/autoprefixer (MIT) ## Screenshots * [[ * The dashboard — monthly quota, savings stats, license management. * [[ * Bulk conversion in progress. * [[ * Per-attachment conversion badges in the media library. * [[ * Settings — quality, output format, auto-convert toggle. ## Installation 1.

Go to the **Tempaloo WebP** menu in your admin sidebar. 4. Click **Generate an API key** (opens tempaloo.com/webp/activate) or paste an existing key. 5. Click **Activate**. New uploads will be converted automatically. 6. (Optional) Go to the **Bulk** tab and click **Start conversion** to convert your existing library. ## FAQ ### Do I need an account to use this plugin? Yes. Conversion happens on our API, so a license key is required. The Free plan ( 250 images/month) takes 10 seconds to generate and requires no credit card. ### What happens if I hit my quota? New uploads stop being converted until the next monthly reset, or until you upgrade. Images already converted keep being served as WebP/AVIF — nothing breaks. ### Are my images stored on your servers? No. Conversion happens in-memory. The converted file is streamed back to your site; the input and output are not persisted. Originals always stay on your server. ### Will it work with my page builder / theme? Yes. The plugin is standalone — it hooks into WordPress’s media pipeline via `wp_handle_upload` and `wp_get_attachment_image`. It works with Gutenberg, Elementor, Bricks, Divi, Beaver Builder, WooCommerce and any theme, without modification. ### Can I uninstall and keep my converted images? Yes. Uninstalling only removes the plugin settings. The `.webp` / `.avif` files we wrote next to your originals stay on your server. Your originals are never touched. ### What’s the difference with ShortPixel / Imagify / Elementor Image Optimizer? They charge one credit per thumbnail WordPress generates (6-8 per upload). We charge one credit per upload, all sizes bundled. For the same monthly quota, you get 6- 8x more usable conversions. ### Does the Free plan require a credit card? No. Paid plans include a 7-day trial and a 30-day money-back guarantee. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “Tempaloo WebP” is open source software.

Highlights: * **WebP & AVIF conversion** — every uploaded image plus all WordPress-generated sizes (thumbnail, medium, medium_large, large, full) are converted to `.webp`( and optionally `.avif`) siblings. Originals are never modified, so restore is one click. * **Async upload pipeline** — conversion runs in a fresh PHP process via a non- blocking loopback request, so uploads finish instantly even on slow hosts and never fight other image-optimizer plugins on the same WordPress filter chain. * **Bulk converter** — convert your entire Media Library in batches, with adaptive backoff on transient API failures, pause / resume on quota or daily-cap, and live progress (current image, savings counter, ETA). * **Pro Media Library column** — per-row format badge, savings breakdown, expandable detail per size, inline restore confirmation. Bulk row-actions for “Optimize selected” and “Restore originals”. * **Picture-tag and URL-rewrite delivery modes** — picture-tag works with every page builder (Elementor, Bricks, Divi, Beaver Builder); URL rewrite stays out of the markup. CDN passthrough mode also supported. * **Diagnostic tab** — state audit (drift detection across filesystem, attachment meta, bulk state, retry queue), reconcile button, per-attachment forensic inspect, filesystem self-test. * **Compatibility hardening** — atomic temp+rename writes, cache-buster on every REST call, explicit `nocache_headers()` + `DONOTCACHEPAGE` so LiteSpeed Cache/ WP Rocket / W3 Total Cache never serve stale admin data. * **Developer hooks** — `tempaloo_webp_skip_attachment`, `tempaloo_webp_quality_for`,` tempaloo_webp_after_convert`. WP-CLI commands: `wp tempaloo status / activate/ bulk / restore / quota`. ## Meta * Version **1.0.0** * Last updated **14 hours ago** * Active installations **Fewer than 10** * WordPress version ** 6.0 or higher ** * Tested up to **6.9.4** * PHP version ** 7.4 or higher ** * Tags * [AVIF](https://wordpress.org/plugins/tags/avif/)[image optimization](https://wordpress.org/plugins/tags/image-optimization/) [images](https://wordpress.org/plugins/tags/images/)[performance](https://wordpress.org/plugins/tags/performance/) [webp](https://wordpress.org/plugins/tags/webp/) * [Advanced View](https://wordpress.org/plugins/tempaloo-webp/advanced/) ## Ratings No reviews have been submitted yet.
