BinsOptimizer – Instant Image Optimizer, Compression & WebP Converter

Changelog

1.6.1

• Fixed: optimizing an existing image changed its URL but left published references pointing at the deleted original, so images already used on the site stopped loading (often reported as a 403 from a security plugin). Those URLs are now rewritten automatically across posts, page-builder data, widgets and theme options — including Elementor’s escaped-slash JSON and serialized values
• New: “Existing images” setting under Compression — choose whether originals are kept as a restorable copy (default) or deleted to save disk space
• New: “Undo optimization” on the Bulk Optimize screen restores originals and points your content back at them
• New: WebP delivery check. Bulk Optimize refuses to start when the server will not serve .webp from the uploads folder, which is what makes optimized images return 403 Forbidden
• Failures during optimization now report the server’s actual reason instead of a generic message

1.6.0

• Admin dashboard is rdesigned with a completely new look for better UX

1.5.0

• New: Bulk Optimize screen — a dedicated dashboard tab that converts your existing JPEG/PNG (and SVG, when enabled) library to WebP, entirely in your browser. Includes progress bar, batch size, pause/resume/cancel, a per-image result log, and a “skip already optimized” toggle.
• New: Optimization Scope setting — choose whether optimizing converts the full-size image only, or the full-size image plus all generated thumbnail sizes (default). Applies to both the Bulk Optimize screen and the per-image “Optimize It” button, so front-end delivery is genuinely optimized.
• New: Grid-view optimization badge — the Media Library grid (and the insert-media modal) now shows a savings badge on each optimized thumbnail, not just the list view.
• New: Per-upload notice — a dismissible summary (“Optimized 3 images — saved 1.2 MB.”) appears after each upload batch and auto-dismisses after 8 seconds.
• New: biio_convert_file JavaScript event — developers can call event.preventDefault() in a listener to skip optimization for specific files and upload the original untouched.
• Improvement: JavaScript-rendered strings are now translatable via @wordpress/i18n, with translations loaded through wp_set_script_translations().
• Improvement: When converting thumbnails, WordPress regenerates WebP sub-sizes from the new file; if the server cannot encode WebP thumbnails, it safely falls back to converting the full-size image only.

1.4.4

• New: Format-specific quality sliders — set separate WebP output quality for JPEG, PNG, and SVG source files instead of a single blunt quality setting.
• Improvement: SVG quality slider appears only when SVG optimization is enabled, keeping the UI clean.
• Improvement: Compression Playground now respects per-format quality settings when previewing conversions.

1.4.3

• New: WordPress Thumbnail Generation control — a master toggle lets you disable all intermediate image sizes on upload to save disk space.
• New: Per-size toggles — selectively disable individual image sizes (thumbnail, medium, medium_large, large, 1536×1536, 2048×2048) while keeping the rest active.
• Improvement: File Size media column is now sortable.

1.4.2

• Added: Reset Default settings button is added
• Checked: compatibility with WordPress 7.0

1.4.1

• Redesign: Premium administrative settings and dashboard redesign with elegant glassmorphic statistics widgets, modern sidebar navigation layout, responsive diagnostics, and widescreen compatibility.
• New: Dynamic real-time calculation of direct space savings, optimized image count, efficiency ratios, and conversion speed directly from your database.
• New: High-fidelity, local browser-based drag-and-drop Image Optimizer Sandbox Playground for real-time before/after side-by-side compression previews.
• Improvement: Beautifully redesigned settings save buttons with animated feedback, state indicators, and sticky tab footers.
• Improvement: Expanded responsive widescreen dashboard layouts to full-width alignment (max-width: 100%).

1.4.0

• New: “Optimize It” button in the Media Library list view — click to optimize any existing JPEG, PNG, or SVG attachment on demand without re-uploading.
• New: File Size column in the Media Library — shows the current on-disk size of every attachment. Can be toggled off in Settings.
• Improvement: Media Library column CSS moved to a dedicated stylesheet (assets/css/media.css) and properly enqueued, keeping PHP templates clean.
• Fix: “Show Filesize Column” toggle was placed outside the settings form and never saved correctly — now included in the form submission.

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.
