QReduce Multi: Crop Compress is a free Android application developed by Mobso Apps. It falls under the multimedia category, specifically photography. This app allows users to compress multiple photos by quality or file size simultaneously. Additionally, users can crop and compress a photo by quality or file size. The app can also compress photos in megabyte size to kilobyte. It is worth noting that the picture will be saved as JPG/JPEG, and transparent and translucent pixels of PNG photos will be lost.

Overall, QReduce Multi: Crop Compress is a straightforward app that is easy to use. The app is suitable for users who need to compress multiple photos at once or reduce the file size of a single photo. However, users who require high-quality images or need to retain transparent and translucent pixels of PNG photos should look elsewhere.
