About the product
Sprite Sheet Builder is a free browser tool for game developers. Drop PNG, JPG, WebP, HEIC frames or a whole GIF, arrange them in a grid or auto-pack, adjust padding and spacing, preview the animation, and export a transparent PNG alone or with a JSON atlas for Unity, Godot and Phaser or Sparrow XML for FNF. Files are processed locally and never uploaded; no watermark and no account. The site also includes a GIF to sprite sheet converter, sprite sheet splitter, animator and an optional AI sprite generator (3 trial images with a verified account, then credits).

For product owners
Promote Sprite Sheet Builder
Every listing gets one post to our X and Threads followers. It is seen once, then the traffic stops. Promotion keeps Sprite Sheet Builder in front of people instead.
- Back in the X and Threads rotation: Sprite Sheet Builder gets posted again instead of once.
- A promoted slot on the AppRater homepage, carrying a Promoted badge.
- A direct link to Sprite Sheet Builder from a DR45 site (Ahrefs Domain Rating), with no redirect in between.
- A labelled spot in the weekly email to AppRater subscribers, one promoted app per issue.
- Stays on the first screen however old the listing is, while new submissions push everything else down.
