Sharpen blurry images in your browser, with optional cloud enhancement.
Sharpniq sharpens blurry images in the browser. Its free on-device mode works without an account, supports output up to 4 MP, and provides PNG downloads. Optional cloud enhancement supports images up to 12 MP and requires sign-in and credits. It is designed for people who want to compare sharpening results while choosing between local and cloud processing. Enhancement cannot guarantee recovery of detail that was absent from the original image.
