Upload a picture and get a plain-language read on how good it actually is - sharpness, real detail, compression damage and exposure - plus how large you can safely print or display it.
How the image quality checker works
Upload the image you want checked. The tool inspects focus and micro-detail, hunts for compression artifacts, noise and banding, reviews exposure and white balance, then gives an overall verdict with the sizes it comfortably supports. It also flags telltale signs that a file was upscaled from a smaller original. Use it when you need to find a high quality version of an image and want to know whether the one you have is already good enough.
Tips for the best results
Upload the original file rather than a screenshot or a messaging-app copy - re-compression changes the answer. Do not resize before uploading. If you have two candidate versions of the same picture, check them one at a time and compare the verdicts to pick the better source.
