Описание
Image Format Converter allows administrators to convert images in the WordPress Media Library between JPG/JPEG, PNG, WebP, and AVIF formats. Using server-side PHP libraries (GD or Imagick), it ensures high-quality conversions with minimal file size. Converted images are saved to the uploads folder and optionally added to the Media Library.
Features:
— Select images via the WordPress media uploader.
— Choose target format (JPG, PNG, WebP, AVIF).
— Configure quality/compression and Media Library integration via a «Conversion Settings» button (admin-only).
— View server library status (GD/Imagick/WebP/AVIF) with a «How to Enable GD and Imagick» button for setup instructions.
— Modern, clean interface inspired by professional design standards (e.g., TinyJPG-like cards and buttons).
— Secure, efficient, and admin-only (no frontend features).
Access all features on Media > Image Converter, with collapsible settings and instructions.

Часто задаваемые вопросы
-
Where do converted images appear?
-
Converted images are saved in your uploads folder (e.g.,
wp-content/uploads/2025/09/) with «_converted» appended (e.g.,image_converted.png). If enabled (default), they appear in Media > Library. The success notice shows «Image convert complete» with links to the file and Media Library entry. -
Why don’t I see the converted file?
-
Check the success/error notice on Media > Image Converter. Ensure GD or Imagick is enabled (see library status). Verify the uploads folder is writable (755/644 permissions). Check Media > Library.
-
What do I do if I see «GD: Not Available | Imagick: Not Available»?
-
Click the «How to Enable GD and Imagick» button for instructions. Summary:
— Shared Hosting: Enable «gd» or «imagick» in cPanel/Site Tools under PHP Extensions. Contact support if needed.

Does it support AVIF/WebP?
-
Yes, if GD (PHP 8.1+ for AVIF, 7.1+ for WebP) or Imagick supports them. Check the library status on the conversion page.
