PNG Pixel asset cutter for game UI and sprite work
PNG Pixel is designed for creators who need to extract small transparent assets from UI sheets, icon collections, and simple sprite images. It focuses on practical browser-based workflows: upload one or more images, remove a solid or simple background, preview the transparent result on light or dark checker backgrounds, review detected candidate assets, and export selected pieces.
This is useful when a single image contains many buttons, icons, item sprites, badges, or interface parts. Instead of manually cropping every item in a large editor, you can process the image locally, inspect the detected candidates, keep the useful pieces, and download the results as PNG files or a ZIP package.
How to use PNG Pixel
- Upload a PNG, JPG, or WebP image that contains UI assets or sprite-like objects.
- Adjust background removal and detection settings until the preview looks clean.
- Use the light and dark preview backgrounds to catch leftover edges or unwanted pixels.
- Review candidate assets, select the useful pieces, and export selected or all results.
- Use ZIP download when preparing a batch of game icons or UI elements.
Privacy and local processing
The asset cutting workflow runs in the browser. Your image is read by the current page and processed with front-end image APIs. The generated assets exist in the page until you download them or leave the page. For confidential files, always follow your own organization’s data rules before using any online tool.
