Fix a Pixelated Image

Usually for one of two reasons. It was saved as a JPEG with strong compression (apps and websites often compress it again each time it's shared), which leaves square blocks and smudged colors. Or it's a small image shown bigger than it is, which turns its edges into staircases. This tool cleans both.

The original file, not a copy that was stretched to a bigger size: stretching turns each pixel into a square the AI may keep as a detail. The tool makes it 4× bigger itself.

No. A part hidden on purpose with a pixel mosaic or a blur has lost its details for good: no tool can bring them back, this one only smooths the squares.

No. It fixes blocks and softness from compression and low resolution, not motion blur or a shot that was out of focus, and it can't add details the photo never had. Very small text may stay unreadable or come out wrong: check it before you use the image.

4× the width and height of the image it works on. An image over 768 px on its longest side is first brought down to 768 px, so the result is at most 3,072 px. It's a PNG, and a transparent background comes back white.
