It works great and is free. You have to watch an ad after you select the photos you want compressed and sometimes you can't close the ad without closing the whole app, but your photos will still have been compressed.
I needed a compression app to downsize pics, and this works perfectly. Right now I'm using the free version, but I plan on getting the pro version with no ads next week. But, if you're looking for an app to do what I am, try it, works great.
Good night all of the day dear the world and in the evening and the evening and the world in the evening of my world is changing my mind and all of a sudden ga of the day dear I was in a meeting at the evening I am a mood for the evening I am a mood of my mind and body works in a meeting with you to be a meeting with the day dear a mood for a student in a meeting with me
Intially I found it confusing with the ads and wasn't sure where the compressed pics ended up. but now that I have figured it out, all is great. excellent in fact. love this app it's halved my upload/download times and data use!
