Title: Endless compression process Last modified: December 17, 2018 --- # Endless compression process * Resolved [AdeP](https://wordpress.org/support/users/adelaidepereira183/) * (@adelaidepereira183) * [7 years, 5 months ago](https://wordpress.org/support/topic/endless-compression-process/) * Hi team, after last update, every time I try to load a new image, the compression process continues endlessly and does not compress it. The only way to stop it is to delete the image. I am not using WordPress 5 – Gutenberg. Thanks for your support.
