Why Sunasty is free
Every tool on Sunasty is completely free, no account, no limits, no watermarks. Here is how that works, and how you can help keep it that way.
Always free, no sign-up
All the tools are free to use as often as you like. There is no account to create, no paywall and no hidden quota. What you process is yours.
Your privacy is the whole point
Your files never leave your device, every operation runs locally in your browser. We do not upload your files and we never sell your data. That privacy is exactly what makes Sunasty worth using.
How it stays free
The site currently runs without any advertising, and nothing you process is ever uploaded or sold. The only measurement is anonymous, consent-gated analytics (GA4) used to understand which tools matter. Hosting and development are covered by the operator; ads or other monetisation may be introduced later, but for now there are none.
How you can help
If a tool saved you time, share it with someone who could use it too, word of mouth is what keeps independent tools alive.
