Yes. Every NeuroScans PDF tool is 100% free with no sign-up, no per-file limits and no watermark on your output. There is no paid tier — all tools are free for everyone.

Are my files uploaded to a server?

No. Every tool runs entirely in your browser using your device’s own processing power, so your PDFs and images are never uploaded. Your files never leave your computer or phone.
