I don't know about other apps for compressing images. But this app, Compress Image is the best app so far. It is so easy to use and result is amazing. I highly recommend this app as it is both effective and efficient.
Does exactly what it says. Reduces file sizes by a lot without removing a lot of quality. Very easy to use and insanely quick. Converts pictures almost immediately and all you have to do for the free version is watch one short ad. Would definitely recommend 👍
This app is certainly the best of its class, and I have used many image compressing programs intermittently over the years. I'd like to contribute to the developer's efforts, and switch off ads. However to ask AU$23 dollars per week subscription fee, or almost AU$50 once off is optimistic in the extreme given that most would be using it modestly.
Here is what you need to know before downloading this app: it works it absolutely works and it did not download any viruses or do any annoying pop-ups or bombard my phone with garbage! I was quickly able to install the app and upload eight pictures and it was able to give me the options to easily compress them or keeping the professional quality of them intact to squeeze them into an email that was time sensitive! And only afterwards did it show ads which I'm fine with dealing :)
