BinsOptimizer - Instant Image Optimizer, Compression & WebP Converter

BinsOptimizer is the fastest, most private way to optimize images in WordPress. Unlike cloud-based image optimizers, BinsOptimizer converts and compresses your images directly in the browser — before they ever hit your server. No API keys, no monthly fees, no privacy risks. Every JPEG and PNG you upload is automatically converted to WebP — the modern image format recommended by Google — and resized to your chosen maximum dimension. The result is smaller file sizes, faster page loads, and better Core Web Vitals scores, all without touching your server resources. Why choose BinsOptimizer over other image optimizer plugins? Most WordPress image optimization plugins send your images to external cloud servers for processing, which is slow, costs money, and raises data privacy concerns. BinsOptimizer does everything on the user's own machine using modern browser APIs, making it instant, free, and completely private.

• Automatic WebP Conversion: Convert JPEG, PNG, and SVGs (if you allow) images to WebP on upload for up to 80% smaller file sizes and better Google PageSpeed scores.
• Client-Side Image Compression: All image processing happens in the browser — zero server load, zero cloud costs.
• Smart Image Resizing: Automatically downscale oversized images to your chosen maximum width or height during upload.
• No API Key Required: Fully self-contained. No third-party services, no subscriptions, no limits.
• 100% Private: Your images are never sent to an external server. Everything stays on your machine until the optimized file is uploaded.
• Zero Queue, Instant Results: Optimization happens in real time as you upload — no background jobs or waiting.
• Media Library Integration: View compression savings, original vs. optimized file sizes, and conversion time directly in the WordPress Media Library.
• Works Everywhere in WordPress: Compatible with the Block Editor (Gutenberg), Classic Editor, drag-and-drop uploads, and featured image pickers.
• SVGs Upload: Allow to upload SVGs file securely and if you want you can optimize and convert them on upload.

1.3.0

• New: Secure SVG upload support — administrators can now enable SVG uploads for specific user roles via Settings > BinsOptimizer.
• New: Role-based SVG upload permission — choose exactly which user roles (Administrator, Editor, Author, etc.) are allowed to upload SVG files.
• New: Server-side SVG sanitization — every SVG is cleaned with a DOMDocument-based sanitizer before it is stored. Strips <script> tags, <foreignObject>, event-handler attributes (on*), dangerous href/xlink:href URI schemes (javascript:, vbscript:, data:application/), and unsafe CSS constructs before saving.
• New: SVG media library compatibility — SVG attachments now display correctly in the Media Library grid and modal, report accurate intrinsic dimensions, and render properly in the Block Editor image block.
• New: SVG frontend display — wp_get_attachment_image() and responsive image helpers work correctly for SVG attachments; srcset generation is disabled for SVGs (vector format needs no size variants).
• New: SVG Auto-Optimization setting — a separate toggle controls whether SVG files are automatically converted to WebP on upload (off by default). When disabled, SVGs are uploaded and stored as native SVG files.

1.2.0

• New: Optimization column added to the Media Library list view — each attachment now shows a colour-coded badge displaying the savings percentage and output format (e.g. "42.3% webp").
• New: Hovering the savings badge reveals a tooltip with the original file size, optimised file size, and total bytes saved.
• New: The Optimization column is fully sortable — click the column header to rank media items from most-saved to least-saved (or vice versa).
• New: Unoptimised attachments display a neutral "Not optimized" badge so the column is informative for every item in the library.
• Improvement: Savings percentage is now also persisted as a dedicated post meta key (_biio_savings) alongside the existing attachment metadata, enabling reliable numeric sorting without serialized-field parsing.

1.1.0

• Fix: Media Library stats panel never rendered in the single-column Details view due to incorrect Backbone template override — switched to a render() override matching the correct pattern.
• Fix: Fatal JavaScript TypeError when conversionTime is absent from stored metadata — added null guard before calling .toFixed().
• Fix: canvas.getContext('2d') could return null for very large images — added explicit null check before drawing to canvas.
• Fix: Metadata queue stored in transients was vulnerable to object-cache eviction — migrated to a persistent WordPress option (biio_metadata_queue).
• Fix: Typo in save-error button label "Fied to Save" corrected to "Failed to Save".
• Fix: Save success button label showed "Saving Changes" after the save had already completed — corrected to "Saved!".
• Fix: Redundant __biio_converted event flag removed; a single biio_converted flag is sufficient to prevent re-processing loops.
• Fix: Removed dead is_admin() guard inside admin_enqueue_scripts hook (the hook already only fires in admin context).
• Improvement: Removed all debug console.log / console.warn statements from production JS bundles.
• Improvement: Deactivation hook now cleans up the persistent option queue instead of a transient.
