# Error reporting; No decoding plugin installed for this compression format

 * Love the plugin!
   Recently, it stopped working and I think it’s due to server-
   side configuration change. Issue 1) is that you don’t handle errors during the
   test_run() and generally don’t output to the error logs if there’s been an issue.
   2) The actual issue:
 *     ```wp-block-code
       ImagickException: Error while loading plugin: No decoding plugin installed for this compression format (11.6003) `/-/wp-content/plugins/heic-support/image4.heic' @ error/heic.c/IsHEIFSuccess/203
       ```
   
 * There hasn’t been any indication in the error logs (even though wp_debug is active),
   nor on the Media settings page. I just happened to dig around the code and the
   above is the output of `$ie->getMessage()`
 *     ```wp-block-code
       ImageMagick 7.1.1-47 Q16-HDRI x86_64 22763 https://imagemagick.orgWordPress 6.6.2PHP-FPM 7.4.33
       ```

 * Hi,
 * Thanks for trying my plugin. If you’ve improved the code, send a pull request!

 * I don’t use this plugin. I don’t know why anyone still needs this plugin since
   the feature was built into core last year [https://make.wordpress.org/core/2024/08/15/automatic-conversion-of-heic-images-to-jpeg-in-wordpress-6-7/](https://make.wordpress.org/core/2024/08/15/automatic-conversion-of-heic-images-to-jpeg-in-wordpress-6-7/)
 * I don’t mind maintaining it, but have you tried deactivating HEIC Support and
   trying an .heic upload since updating to WordPress 6.7?
 * Thanks again.

 * Upon investigation, I found that WordPress provides native support for HEIF/HEIC
   format and preserves the original files without deletion. In contrast, certain
   third-party plugins encounter problems (such as CompressX failing to generate
   thumbnails and AVIF conversions from the original HEIF/HEIC files). As a result,
   I ultimately decided to continue using your plugin

 * it’s any way to use your plugin to Bulk Optimization the old heif/heic original
   files to jpeg?

 * Thanks for the update!
 * No, there are no unlisted features of this plugin. I would handle bulk conversions
   with shell scripting and SSH access to the server with something like this…
 *     ```wp-block-code
       for file in *.heic; do    magick "$file" "${file%.heic}.jpg"  done  
       ```
   
 * …and the [`wp media import`](https://developer.wordpress.org/cli/commands/media/import/)
   command create Media Library items.
