Encountering a Conversion Error?

Converting images can sometimes lead to various error types. Here’s what you can do when facing errors:

  1. File Not Found Error (“File “%s” does not exist. Please check file path.”): This error means that the file specified in the given path doesn’t exist. Verify the path to ensure it’s accurate.
  2. Unreadable File Error (“File “%s” is unreadable. Please check file permissions.”): This error indicates that the file’s permissions prevent it from being read. Check both the file’s permissions and the directory where it resides.
  3. Invalid Image File Error (“%s” is not a valid image file.): If you receive this error, the file might be corrupted. Download it, open and save it using a graphics program, and then re-add it to your page.
  4. WebP Conversion Error (“Image “%s” converted to .webp is larger than original…”): This error occurs when the original image size is smaller than the WebP version. This could be due to previous compression. You can disable the “Automatic removal of files in output formats larger than original” option in the plugin settings to ensure WebP usage.

Always review the error messages carefully, as they often provide insights into the issue. Most errors can be resolved by checking paths, permissions, and the condition of the image files. If you need further assistance, don’t hesitate to reach out to the server administrator or support.
