Neither. Glide heavily caches your images and optimizes them per device, changing their format and resolution to load optimally for each operating system and screen density.

I’m guessing that you’re asking because you’ve updated an image and it’s not updating in your app. If so, please see [How can I cause my images to update whenever they change?](https://community.glideapps.com/t/how-can-i-cause-my-images-to-update-whenever-they-change/364)
