Description

From the listing uploaded by “apps”.

Image Optimizer optimizes allows you to save space on your smartphone by optimizing your image files. Image Optimizer supports two optimization techniques, you have the choice: ★ compress your photos to save a big amount of space with a slight, often unnoticeable quality loss ★ just optimize your picture while retaining the original quality If you have questions, bugs, suggestions, please contact me by mail, don't use the market comment as It's impossible for me to reply and help you! Both JPEG and PNG files are supported! Notes: ★ some devices with few space already compress images with an high ratio, so it's normal to save a few bytes or nothing at all, since Image Optimizer will never save a new image bigger than the original! ★ EXIF tags are always preserved, so you will not lose creation date, location, rotation

Image Optimizer APK: questions and answers

Can I install this APK over the version I already have?

Only if it is signed with the same certificate as the copy on your phone and isn't an older version. If Android says “App not installed”, the certificates differ; uninstalling your copy first works but deletes its data unless it is backed up.

Is the Image Optimizer APK safe?

No one can promise that a file is safe, but some things can be checked. The source store rates this file Trusted. After downloading, check that the file's MD5 is 0ee52b845d11905edf85ef3153746205.
