Frequently Asked Questions about Pixel Snapper

Can I use Pixel Snapper's web edition without paying or signing up?

Yes. The web edition is completely free and requires no account to use. You upload your messy pixel art, Pixel Snapper cleans it up and aligns it to a perfect grid, and you download the result. There are no login walls or paywalls on the free version.

What file formats does Pixel Snapper accept, and how large can they be?

Pixel Snapper accepts PNG and JPG files up to 10MB each. If your AI-generated pixel art exceeds that limit, you may need to resize or compress it first before uploading to the web edition.

Does the desktop edition support batch processing of multiple pixel art files?

Yes. The desktop edition offers batch processing, which lets you clean up many pixel art files at once instead of one by one. This makes it useful for preparing large numbers of sprite sheets or game assets. The desktop edition is a one-time purchase at $7.99 (regularly $9.99) and includes free lifetime updates.

Will Pixel Snapper preserve dithering and fine details when it cleans up my pixel art?

Yes. Pixel Snapper is built to preserve dithering, curves, and other fine details while it fixes off-grid pixels and snaps them to a perfect grid. This means you keep the texture and character of your AI output while gaining the precision you need for game engines and sprite sheets.
