FAQ
Is my image uploaded anywhere?
No. The AI model runs entirely in your browser. Your image never leaves your device — that's why it's free with no signup.
How much can I enlarge an image?
Up to 4× the original dimensions on the free tier. The input is capped at 1200px on the longest side so the result stays fast and memory-friendly.
Why does the first run take longer?
The first time, a small (~5 MB) AI model downloads to your browser and is cached. Later runs skip the download.
Does it work on blurry or low-quality photos?
It adds detail and sharpness when enlarging, which helps mildly soft images. For heavily blurred photos, try our Blur Image Fixer too.
