Best for image compression. You can compress image size completely according to you. It gives more features like manual compression, auto compression etc. which makes it more handy to use and also increases its efficiency.
So far, so good! I appreciate the option to use advanced features without a commitment, by watching ads, if you need to use them only occasionally. It helps to explore the pre-set options to see what resolutions and file sizes you get from each preset compared to the input file. The options to enter custom values and exert full control over the compression values is essential flexibility I appreciate.
Love this app!! I have only used it for compressing photos so don't know what else it may do but for making the file size small enough to be able to send numerous photos at a time through email or similar, without getting the dreaded "file size is too large" message, it's done the job perfectly for me. Many times!
Edit- I see. I am updating my rating, but I wish app description was clearer about the fact that it only converts to jpg. Also the location of compressed image should have been clearer. It was the smallest text and in white colour. I completely missed it before.
