Photo Compressor and Resizer
Photo Compressor and Resizer helps you quickly compress, resize, convert, and crop images while preserving quality and saving storage space. It uses intelligent lossy compression to selectively reduce color data, minimizing file size without visible degradation, and supports batch processing so you can compress multiple photos at once to a specified file size in KB or MB. The app offers two compression modes along with photo resizing functions to reduce or enlarge images and change resolution. Crop tools let you remove unwanted areas using a variety of aspect ratios, and conversion between JPEG, JPG, PNG, and WEBP formats is built in. Additional utilities include a color picker to extract hues from images and a Material Design color palette. By keeping the original photo intact until you choose to replace it, this free app streamlines image optimization for mobile devices and tablets without affecting picture quality.
