Frequently Asked Questions

How is it so fast?
We don't use backend servers. By leveraging WebAssembly and HTML5 Canvas, your browser's CPU does all the heavily lifting instantly.
Do you store my uploaded images?
No. It is impossible for us to store your images or data because they are never transmitted across the network in the first place.
What's the catch? Why is it free?
We built this tool suite because we were tired of encountering paywalls for simple utilities. It's free because running client-side apps costs us virtually nothing in server fees.
