Image Enlarger — Upscale Image 2×/3×/4×
Enlarge a small or low-resolution photo 2×, 3× or 4× while sharpening edges on the way up — for an old, small photo that needs to be bigger for a print or an upload that demands a minimum resolution.
What it does
- Smart edge-sharpening reduces the blur that simple stretching causes.
- Choose 2×, 3× or 4× enlargement depending on how much bigger you need it.
- First use downloads a small on-device model (a few MB) — after that it works offline.
Private by design
Processing runs entirely inside your browser tab — your photo or document is never uploaded to a server.
Good to know
You can redo the same photo or file as many times as you like with different settings — each attempt starts from your original, so nothing gets permanently altered on your device either.
How it works
Frequently asked questions
Is this the same as AI photo restoration?
No — it's a smart enlarge-and-sharpen, not full AI reconstruction, so it won't invent detail that isn't in the original photo; results differ from paid AI-restoration tools.
Does it need the internet every time?
Only the first time, to download the small on-device model — after that it runs offline in your browser.
