Lymio is a WordPress plugin that leverages WebAssembly and ONNX models to remove backgrounds from images entirely within the user's browser, requiring no external APIs or monthly fees.
What is Lymio?
Lymio is a background removal plugin for WordPress that processes images locally using WebAssembly and ONNX runtime. It takes any image from the Media Library or user uploads and outputs a transparent PNG or WebP with the subject isolated. The plugin is offered by the same vendor as the Palleon WordPress image editor.
Key Features
- Zero API Costs — Processes images locally using Web Workers; no third-party API calls or per-image fees.
- Privacy First — All processing occurs on the user's machine; images never leave the server.
- Instant Speed — Optimized ONNX runtime downloads models once (cached in browser), making subsequent edits fast.
- 3D Compositing — Allows positioning the subject across X, Y, and Z planes to compose new backgrounds.
- Bulk Background Removal — Remove backgrounds from multiple images simultaneously with pause/resume controls from the Media Library.
- WooCommerce Integration — Dedicated AI Studio for product photos, including galleries and variations.
- Frontend Shortcode — Embed the
[lymio]shortcode on any page for visitors to remove backgrounds.
Who is it for?
- WooCommerce store owners — who need to create uniform, distraction-free product images for their catalogs.
- WordPress site managers — who want to streamline media library workflows and maintain consistent image styling.
- Photographers and designers — who require high-quality background removal on large batches of images without external software.
- Website visitors — when the plugin is embedded via shortcode, allowing them to remove backgrounds from their own images.
What can you do with Lymio?
- E-commerce product photography — Remove distracting backgrounds from product images to create white-background listings that boost conversion rates.
- Bulk media cleanup — Use the bulk background remover to process hundreds of images from the Media Library in one batch.
- Frontend user experience — Offer background removal as a free tool on your site using the shortcode, increasing engagement without server costs.
How does Lymio work?
Lymio downloads the AI models (around 200 MB) to the user's browser cache on first use from a global CDN. Each subsequent processing runs entirely in the browser via WebAssembly, taking under a few seconds per image. The plugin then overwrites the original file in the WordPress Media Library with the background-removed version, using cache-busting to update everywhere.
Pricing
Lymio is a paid plugin with a one-time license fee of $14.99 (as displayed on the pricing page).
Alternatives
- Remove.bg — an API-driven background removal service that charges per image and requires internet connectivity.
FAQ

Does it overwrite my original WordPress Media files?

How large are the AI models and will they slow down my site?
The models are around 200 MB and are hosted on a global CDN. They are downloaded once to the user's browser cache, not to your server, so they do not affect site performance.
