Frequently Asked Questions

Can I apply multiple filters at once?

Yes. Filters stack, and each one builds on the previous result. You can adjust or remove any filter in the chain.

Does this work like Instagram filters?

Similar idea — you get a set of visual effects to apply. The difference is you have per-filter intensity control for more precise adjustments.

Are my images processed on a server?

No. Everything runs in your browser using canvas and CSS filter operations.
