Image effect workflow
Invert one or more images locally in your browser, preview before/after results, and download individual PNG files or a ZIP.
Preview and export
Privacy and local cleanup
Images are inverted with browser canvas. They are not uploaded to Wanglitou servers for this action.
使用 Clear local files after downloading to remove selected images, previews, and generated output objects from the page.
When to use inverted images
- Create high-contrast visual variants for design review.
- Inspect dark/light composition quickly.
- Prepare playful effects for social posts or teaching examples.
- Batch export inverted PNG files without opening a heavy editor.

よくある質問
Does this upload my images?
いいえ. The inversion happens in your browser with canvas.
Why does export use PNG?
PNG keeps the canvas output predictable. If file size is too large, run the exported file through Compress Image afterward.
Can I remove generated results?
はい. Use Clear local files to remove selected files and generated results from the current page.
