Frequently Asked Questions

What does inverting the alpha channel do?

It flips the transparency values. Parts of the image that were fully opaque become fully transparent, and parts that were transparent become opaque. Semi-transparent pixels are also flipped accordingly.

Can I process JPG images?

Yes, but since JPG doesn't support transparency, the entire image is treated as fully opaque. Inverting it will make the whole image fully transparent.

Is there a limit to the number of files?

There is no hard limit. Our tool is designed to handle hundreds of images efficiently, though performance may vary based on your device's memory.
