Two Ways to Reduce Image Size: Quality vs. Dimensions
Image file size is determined by two factors: total pixel count (width × height) and compression encoding density (bits per pixel). PrintReady gives you full control over both: reduce compression quality for lightweight files, downscale pixel dimensions, or execute both simultaneously.
Safe, Client-Side Image Processing
Unlike traditional online converters that upload your photos to remote cloud servers, PrintReady processes everything locally in your browser memory using HTML5 Canvas. Your files are never stored or analyzed.
