Frequently asked questions
Are my images uploaded to a server?
No, they aren't uploaded. Boltpic doesn't send your images to a server — it processes them right in your browser. That means your image files are never stored anywhere else, so you can work more safely and faster.
Do I need to install anything or sign up?
No, you don't. You don't have to install an app or create an account — you can use it straight from your browser. Just pick the tool you need and load your image.
Is Boltpic free to use?
Yes, Boltpic is a free image toolkit anyone can use. You can freely use the main features — color extraction, gradient generation, resizing, format conversion, compression, and more.
