Coding974 AVIF & Imagick Optimizer

PrestaShop 8.1+ / 9 module that speeds up product image generation by replacing GD with Imagick and enabling next-generation AVIF and WebP output.

By Coding974.

⚠️Compatibility: PrestaShop 8.1.0 minimum. The AVIF format and the ImageManager::resize() signature used here only exist from 8.1 onwards. On 1.7 and 8.0 the override would cause a fatal error — installation is therefore deliberately blocked below 8.1 (guard in install()).

Why

  • AVIF / WebP: images up to 50% lighter than JPEG at equal quality → faster pages, better SEO, less bandwidth.
  • Imagick > GD: better resizing quality (Lanczos filter) and correct EXIF orientation handling.
  • Faster generation thanks to two built-in optimizations:
    1. Decoded source caching — on upload, PrestaShop resizes the same photo ~10 times (5 JPEG formats + 5 AVIF). The image is decoded only once (~20 ms per clone instead of ~450 ms of re-decoding per format).
    2. Fast pre-scaling — on large studio photos (>3× the target size), a sampling-based reduction runs before Lanczos → ~10× faster, identical final quality.
  • Automatic GD fallback: if Imagick is missing, the module stays safe and uses GD.

Requirements

  • PrestaShop 8.1.0 or higher (native AVIF).
  • PHP with the Imagick extension enabled, ideally compiled with AVIF support (ImageMagick ≥ 7.0.25 + libheif/libaom). Without AVIF in Imagick, the other formats (JPEG/PNG/WebP) still work.
  • PrestaShop quality settings are respected: PS_JPEG_QUALITY, PS_PNG_QUALITY, PS_WEBP_QUALITY, PS_AVIF_QUALITY, PS_IMAGE_QUALITY, PS_IMAGE_GENERATION_METHOD.

Installation

Recommended — from the release: download the ZIP from the latest release, then in the back office: Modules → Module Manager → Upload a module → select the ZIP.

Then (for both methods):

  1. ⚠️Only one override per method. If the shop already has a manual override/classes/ImageManager.php override, delete it BEFORE installing the module (otherwise installation fails or refuses to copy the override).
  2. Install "Coding974 AVIF & Imagick Optimizer" from the Module Manager. PrestaShop automatically copies the override into override/classes/ and rebuilds the class index. (Installation is refused if the version is < 8.1.0.)
  3. Regenerate thumbnails: BO → Preferences → Images → Regenerate thumbnails, to produce the new formats for the existing catalogue.

(Manual installation: copy the coding974avifoptimizer/ folder into modules/, then install it from the back office.)

Uninstallation

Uninstalling the module from the back office removes the override and returns PrestaShop to GD. Clear the cache if needed.

Technical notes

  • The override extends ImageManagerCore and overrides resize(), create(), thumbnail() as well as the MIME_TYPE_SUPPORTED / EXTENSIONS_SUPPORTED lists (adding AVIF/WebP/SVG).
  • The source cache is static: it only lives for the duration of the PHP request, with no persistent memory footprint.
  • Everything is wrapped in try/catch blocks with GD fallback and logging via error_log.

Compatibility

PrestaShop 8.1.x, 9.x. Single or multi-shop. (1.7 / 8.0 unsupported: no AVIF.)

Installation
Recommended — from the release:
download the ZIP from the latest release, then in the back office:
Modules → Module Manager → Upload a module → select the ZIP.
Then (for both methods):
  1. ⚠️Only one override per method. If the shop already has a manual
override/classes/ImageManager.php override, delete it BEFORE installing the module
(otherwise installation fails or refuses to copy the override).
  2. Install "Coding974 AVIF & Imagick Optimizer" from the Module Manager.
PrestaShop automatically copies the override into override/classes/ and rebuilds the
class index. (Installation is refused if the version is < 8.1.0.)
  3. Regenerate thumbnails: BO → Preferences → Images → Regenerate thumbnails, to
produce the new formats for the existing catalogue.
(Manual installation: copy the coding974avifoptimizer/ folder into modules/, then
install it from the back office.)
Uninstallation
Uninstalling the module from the back office removes the override and returns PrestaShop
to GD. Clear the cache if needed.
Technical notes
  • The override extends ImageManagerCore and overrides resize(), create(),
thumbnail() as well as the MIME_TYPE_SUPPORTED / EXTENSIONS_SUPPORTED lists
(adding AVIF/WebP/SVG).
  • The source cache is static: it only lives for the duration of the PHP request, with
no persistent memory footprint.
  • Everything is wrapped in try/catch blocks with GD fallback and logging via error_log.
Compatibility
PrestaShop 8.1.x, 9.x. Single or multi-shop. (1.7 / 8.0 unsupported: no AVIF.)

Coding974 AVIF & Imagick Optimizer
PrestaShop 8.1+ / 9 module that speeds up product image generation by replacing
GD with Imagick and enabling next-generation AVIF and WebP output.
By Coding974.
⚠️Compatibility: PrestaShop 8.1.0 minimum. The AVIF format and the
ImageManager::resize() signature used here only exist from 8.1 onwards. On 1.7 and 8.0
the override would cause a fatal error — installation is therefore deliberately blocked
below 8.1 (guard in install()).
Why
  • AVIF / WebP: images up to 50% lighter than JPEG at equal quality → faster pages,
better SEO, less bandwidth.
  • Imagick > GD: better resizing quality (Lanczos filter) and correct EXIF orientation
handling.
  • Faster generation thanks to two built-in optimizations:

    1. Decoded source caching — on upload, PrestaShop resizes the same photo ~10 times
(5 JPEG formats + 5 AVIF). The image is decoded only once (~20 ms per clone
instead of ~450 ms of re-decoding per format).
    2. Fast pre-scaling — on large studio photos (>3× the target size), a sampling-based
reduction runs before Lanczos → ~10× faster, identical final quality.
  • Automatic GD fallback: if Imagick is missing, the module stays safe and uses GD.
Requirements
  • PrestaShop 8.1.0 or higher (native AVIF).
  • PHP with the Imagick extension enabled, ideally compiled with AVIF support
(ImageMagick ≥ 7.0.25 + libheif/libaom). Without AVIF in Imagick, the other formats
(JPEG/PNG/WebP) still work.
  • PrestaShop quality settings are respected:
PS_JPEG_QUALITY, PS_PNG_QUALITY, PS_WEBP_QUALITY, PS_AVIF_QUALITY,
PS_IMAGE_QUALITY, PS_IMAGE_GENERATION_METHOD.
