Image Format Converter Reviews, Downloads & Maintenance

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.

Installation

Upload the image-format-converter folder to /wp-content/plugins/.
Activate the plugin through the Plugins menu in WordPress.
Navigate to Media > Image Converter to convert images, adjust settings, or view GD/Imagick instructions.

Frequently Asked Questions

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.
– Local (XAMPP/WAMP/MAMP): Edit php.ini to uncomment extension=gd or add extension=imagick after installing ImageMagick.
– VPS (Ubuntu/CentOS): Install php-gd or php-imagick, restart Apache.
– Cloud (AWS, DigitalOcean): Install extensions or contact support.
– Verify: Use Tools > Site Health > Info > Server or create info.php with <?php phpinfo(); ?>.

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.

Why don’t the toggle buttons work?

Open Developer Tools (F12 > Console) for errors like “jQuery is not defined”.
Ensure wp-content/plugins/image-format-converter/admin/js/imgfmt-admin.js exists (permissions 644).
Deactivate other plugins and switch to a default theme (e.g., Twenty Twenty-Five).
Clear browser cache or test in incognito mode.
Enable WP_DEBUG in wp-config.php and check wp-content/debug.log.
Verify jQuery loads (F12 > Network > JS).
In XAMPP, ensure Apache is running and file paths are correct.
Contact support with console errors.

Can I convert multiple images?

Currently supports single-image conversion. Bulk conversion is planned for future updates.
