What Incod Image Dimension Manager Can Do

Everything you need to keep every image on your site perfectly uniform — with no limits and no server stress.

Settings: target size, resize modes, canvas color and processing scope
Resize Modes

Letterbox, Hard Crop or Proportional Scale

Pick one of three modes to unify every image to the exact target dimensions, with full control over the canvas and the crop point.

  • Letterbox / Canvas — pads the empty space with a custom HEX color or a fully transparent canvas (PNG/WebP), always centered
  • Hard Crop — fills the target exactly, with a focal point: Center, Top, Bottom, Left or Right
  • Proportional Scale — resizes without adding canvas and without destructive cropping
  • Option to prevent upscaling of images smaller than the target
  • Configurable JPEG quality from 1 to 100%
  • Images already matching the target are skipped automatically
Settings: post types selection, automation, backup and batch options
Scope & Automation

Every Post Type, Precisely Scoped

All public Custom Post Types are detected dynamically — WooCommerce included — so you decide exactly which images are processed.

  • Dynamic detection of every public CPT with multi-checkbox selection
  • Choose the whole Media Library or only the images used by the selected post types
  • Featured images, attached files, WooCommerce product galleries and product variations
  • Auto-resize on upload: every new image is adapted automatically
  • Optional backup of the originals with batch restore from the Bulk screen
  • Batch size (1–50) and JPEG quality right from the settings screen
Bulk Resize screen with progress bar, statistics and error log
Bulk Processing

Bulk Resize With No Limits

Process your entire library asynchronously: the browser sends small batches while the server always stays within its comfort zone.

  • Fluid progress bar with percentage, counters, elapsed time and estimated remaining time
  • Pause, Resume and Cancel at any moment — no limit to the number of images
  • Timeout protection: time budget per request, adaptive throttle and mutual-exclusion lock
  • Error log (last 50) and session state stored on the server
  • Retries on failure: nothing is lost between batches
  • Imagick engine with automatic GD fallback via wp_get_image_editor()

Why Incod Image Dimension Manager

Built for site owners and store managers who want a coherent look across every page, archive and gallery — without babysitting the server.

Three Resize Modes

Letterbox with colored or transparent canvas, Hard Crop with focal point, and Proportional Scale — in a single plugin.

Smart Canvas

Fill empty space with any HEX color through the color picker, or use a fully transparent canvas for PNG and WebP images.

No Image Limits

Batches of 1–50 images per request and no cap on the total: process ten or one hundred thousand images with the same flow.

Timeout Protection

Time budget per request, adaptive throttle between batches and a mutual-exclusion lock: the server is never saturated.

Dynamic CPTs

Every public Custom Post Type is detected automatically and selected with checkboxes — no configuration needed.

WooCommerce Ready

Product featured images, the _product_image_gallery and even product variation images are fully supported.

Auto-Resize on Upload

New uploads are resized automatically through wp_generate_attachment_metadata, with a recursion guard.

Originals are copied to idim-backups before being overwritten and can be restored in batches, with progress.

Secure & Translatable

Capability checks, nonces, sanitization and escaping everywhere, plus a full .pot file. GPL 2.0+, WP 5.0+, PHP 7.4+.

Frequently Asked Questions

Everything you need to know about Incod Image Dimension Manager.

No. If you enable Keep a backup of the originals, every file is copied to wp-content/uploads/idim-backups/ before being overwritten and can be restored from the Bulk Resize screen, in batches with progress.

The plugin automatically uses GD. The engine is selected through the native wp_get_image_editor() function, so no configuration is required.

No. The bulk process works in configurable batches (1–50 images per request) with no quantitative limit. Every request has its own time budget: images that are not processed yet are simply deferred to the next request.

No. Each batch is interrupted at the time budget, the pause between batches adapts to the load just processed (adaptive throttle), and a mutual-exclusion lock guarantees that only one session works at a time. If a request times out, the plugin retries it automatically.

You can, but it is better to keep it open: the processing loop lives in the browser. The session state is stored on the server anyway and is shown the next time you open the Bulk Resize screen.

Yes. The WooCommerce product is detected automatically among the Custom Post Types and both the featured image and the product gallery are processed, including product variation images.

WordPress 5.0 or later (tested up to 7.1), PHP 7.4 or later and Imagick or GD (almost always already present on any hosting). No external dependencies or third-party services.

Upload the incod-image-dimension-manager folder to /wp-content/plugins/ (or install the plugin as a zip), activate it from the Plugins screen, then go to Incod Image Dimensions → Settings to set the target size, mode and scope, and open Incod Image Dimensions → Bulk Resize to process your existing images.
