FAQ
Are my images uploaded to a server?
No. Processing runs entirely in your browser. Your files never leave your device.
Is it safe for private photos?
Yes. Images stay on your device. EXIF and metadata are not sent to any server.
Why does the first run take longer?
AI models download once to your browser (typically 5–30 MB), then are cached. Later runs are much faster.
Does this use a paid AI API?
No. Open-source models run locally in your browser. There is no per-image API charge.
When should I sharpen?
Use on slightly soft or mildly blurry photos. Heavily blurred images cannot be fully restored.
