Questions about nopa apps
Are these apps really free?
Yes. Every app on this page is free — no signup and no payment after your result.
Is my data uploaded to a server?
No. Every app processes your file in the browser — nothing is uploaded. AI apps like background removal or transcription download a one-time model, but your file itself never leaves your device.
What is the nopa desktop?
A desktop in your browser: save results to Files, reuse them across apps, and everything stays on your device.
