Frequently Asked Questions

Is OptiPix.art really free?
Yes. All 131 tools are free with no usage limits, no watermarks and no premium tier. The site is paid for by advertising.
Are my files uploaded to a server?
No. Every tool runs entirely in your browser using WebAssembly. Your files never leave your device. OptiPix cannot see, access, or store your files.
Does OptiPix work offline?
No, and this is worth being precise about. The page has to load over the network, and an AI tool downloads its model the first time you use it. What does not happen is an upload: once a tool is open, your file is processed on your own device and never sent anywhere.
Do I need to create an account?
No. There is no signup, no login, and no account required. Just open a tool and start using it immediately.
What browsers are supported?
OptiPix works on all modern browsers including Chrome, Firefox, Safari, and Edge. Mobile browsers are fully supported. Some AI tools perform best on desktop with WebGPU support.
How is OptiPix different from TinyPNG or Canva?
Unlike TinyPNG, Canva, and similar tools, OptiPix processes everything locally in your browser. Your files are never uploaded to any server. There are no account requirements, no usage limits, and no subscription fees.
