Free image resolution checker. Check photo resolution, dimensions, DPI, and compression online. See if your image is high-res enough for print or social media.
QualityImage resolution determines where your photo can be used effectively. A 12MP smartphone photo works for web and social media, but may struggle at large print sizes. Our quality analyzer reads the actual pixel dimensions, calculates effective DPI for common print sizes, and evaluates compression, sharpness and noise as four separate readings rather than one combined score.
Web images need 72 DPI minimum. Social media platforms resize to their own dimensions. Print requires 300 DPI at the target size. Our tool calculates all of these from your actual pixel data.
