Frequently Asked Questions

Common questions about Image Quality Control | Still BE

No, it will not be lost.

There is no need to rewrite. If user browser supports WebP, .htaccess will automatically deliver WebP instead of JPEG or PNG.

Not required. If you want to compress the uploaded images with the new settings, recompress it. Recompression is recommended when creating a new WebP. (WebP for uploaded images is not automatically generated) The image sharpness of WebP is not good. Raise the quality level of WebP. Test the file size and image quality to decide the quality level.

It cannot be done. You can only specify whether you want to delete all or keep it.

Yes, you can. Recompression will delete the EXIF according to the current settings.

Yes, it will stop. If you install '.htaccess' properly in /wp-content/uploads, it can be delivered automatically even after it is stopped.

Yes, it has priority. (Version 0.10.9+)

Just deactivate it from the plugins (admin screen) and then delete it. There is no cache or database, so there is nothing you to do after uninstalling. If an image that was of poor quality is recompressed with higher quality, there will be no change in the image. It is possible that the browser cache is still active. Clear the browser cache or update this plugin to Version 1.2.0+. Version 1.2.0+ will clear the cache when there is a change in the image.

It lowers the quality level of each resized image until the target visual quality is reached, using SSIM (structural similarity) as an objective quality metric.

This process runs automatically in the background, one image after another. (Disabled by default.)
