This app batch compresses and offers to replace existing files in their place without losing time stamp and meta data. The developers consider the UX from usability stand point better than their competitions.
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.
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!
This is the first time I was able to send documents because they were always too large and I was unable to make them smaller on my phone. I'm not very savvy when it comes to computers and cell phones. It was so simple using this app I could not believe it. I am so thankful to you guys for making a extremely difficult situation easy for me I am going to share this with everyone I know thank you!
