What It Does

• Import local files, folders, ZIP archives, or images found from web pages.
• Preview Current and Final output side by side before exporting.
• Apply cleanup, color, detail, transparency, GIF, export, and encoding controls.
• Remove white or black backgrounds when you choose to, without forcing it on import.
• Use presets for faster sprite, photo, GIF, and mixed-format workflows.
• Batch process large queues with presets, background overrides, file naming, and export rules.
• Export to PNG, WEBP, JPG, GIF, ICO, TIFF, and BMP.

Download

The easiest way to use the app is the latest Windows release:

Sprite Factory Pro Releases

Download the .exe, run it, then import files from the top Import menu or use the Web Sources tab.

Main Workflow

1. Open a new session or continue working in the current workspace.
2. Import files, folders, ZIPs, or scan web pages for sprite/image links.
3. Select an asset from the workspace.
4. Choose a preset or adjust edit settings manually.
5. Use Preview to check the result in the final pane.
6. Use Apply when you want to commit the edit to the asset.
7. Export one file, skip to the next asset, or open Batch Manager for queue export.

Web Sources

Web Sources is built for collecting sprite/image links from normal websites, not just one specific site.

• Save useful pages so you can scan them again later.
• Paste direct page URLs or a manual list of page URLs.
• Find linked index/category pages, filter the list, then scan only the pages you need.
• Filter found files by PNG, GIF, WEBP, JPG, or ZIP.
• Large scans warn before running so you do not accidentally overload the app or site.

Batch Manager

Batch Manager processes selected workspace assets with a separate batch workflow so normal preview/edit state does not get tangled with queue export.

• Copy current edits when needed.
• Apply a chosen preset or smart preset rules.
• Override background-removal behavior for the batch.
• Keep source names or use batch naming rules.
• Save files after processing and review failures clearly.
