Frequently Asked Questions

Common questions about MediaSpark – AI Image Optimization, WebP, AVIF & Alt Text

Yes. The free version on WordPress.org includes WebP + AVIF generation, bulk compression, lazy loading, AI alt-text, media folders, and bulk editing — forever, with no email wall, no banner ads, and no required signup. Pro is optional and adds AI tagging, watermarking, advanced compression profiles, and CDN-ready URLs.

Three differences. (1) No email wall — you don't have to register an account to use what's bundled in the free plugin. (2) No banner ads in your wp-admin. (3) Filter-only architecture — every behavior is a WordPress filter you can disable or override. We're also one of five sister plugins on a shared AI credit pool, so if you also use Clarity SEO Pro or SiteFix Pro, your credits compound across them.

Yes — AVIF generation is included in the free version, alongside WebP. AVIF typically delivers 30–50% smaller files than WebP at equivalent visual quality, and is supported by Chrome, Edge, Firefox, Safari, and Opera. MediaSpark serves AVIF with a WebP fallback for older browsers automatically.

Pro plans include monthly Premium AI credits (50 / 200 / 1000 depending on tier) that power AI alt-text generation, AI tagging, and AI scene detection. Credits are shared across all PluginJoy Pro plugins on your account — so the same credit pool powers MediaSpark, Clarity SEO, and SiteFix. Top-up packs are available and credits never expire. The free version of MediaSpark uses a lightweight on-device alt-text generator (no AI credits required).

Open Media → MediaSpark → Bulk Optimize. Choose your quality preset (Lighthouse-friendly defaults included), pick a batch size, and start. Optimization runs in the background via WordPress's standard cron — you can close the page and come back later. Originals are kept by default (you can disable retention to reclaim disk space).

The opposite. MediaSpark generates smaller image variants (WebP / AVIF) and adds native browser lazy loading, both of which improve Lighthouse / Core Web Vitals scores. There is no front-end JavaScript injected, no jQuery dependency, and no inline stylesheets — it's purely server-side rewriting via WordPress filters.

Yes. MediaSpark optimizes WooCommerce product images, variation images, and gallery thumbnails out of the box. Bulk optimize handles existing product catalogues; new uploads are auto-optimized.

In your Media Library, select multiple files using checkboxes. Choose a MediaSpark action from the "Bulk Actions" dropdown: MediaSpark: Bulk Optimize — generate WebP / AVIF variants MediaSpark: Assign to Folder — select or create a folder MediaSpark: Assign Tags — select or create tags MediaSpark: Set Alt Text from Title — instant, no confirmation MediaSpark: Set Custom Alt Text — type custom alt text for the batch
