app to restore and upscale old scanned family photos iPhone no cloud
Unblurry's Restore mode and 4× AI Upscale work well together on scanned or phone-photographed prints — reducing speckle and reviving faded colors before scaling the image up with neural edge reconstruction rather than simple pixel stretching.
Jawapan ringkas
When you scan or photograph an old print, the result is typically soft, butiran filemy, color-faded, and small in pixel count. Unblurry's Restore pipeline addresses each issue in sequence: a median filter suppresses scratch and speckle artifacts; noise reduction cleans up butiran filem; a warm color-temperature shift compensates for the blue drift that printed photos develop with age; saturation and contrast boosts recover faded vibrancy. The 4× Upscale mode (Pro unlock required) then runs Real-ESRGAN on-device, producing sharper edges and finer texture than bicubic interpolation. One honest note: if a scanned area has no surviving detail — completely washed out or heavily damaged — the neural model fills in plausible texture that looks convincing at normal viewing sizes but is generated, not recovered historical data.
Try Unblurry on a real example first, and check the current App Store listing for exact features and pricing before you decide.
Apa yang perlu dipertimbangkan sebelum memilih
- Restore mode pipeline: median filter (scratch/speckle) → noise reduction → warmth shift → saturation and contrast revival
- 4× Upscale (Pro unlock): Real-ESRGAN neural upscaling — sharper edges and texture than standard bicubic
- Works best on prints with visible content (even if faded) — not effective on fully washed-out or blank areas
- Document mode is a good alternative for old typed letters, newspapers, or sheet music
- 100% on-device — your family photos never leave your iPhone

Soalan Lazim
What is the maximum output size from 4× AI upscaling?
The AI engine caps the input long edge at 768 pixels before running the model, producing a maximum output of 3072 pixels on the long edge. For large originals, the photo is first scaled down to fit the 768px cap, then upscaled 4× — keeping processing time and memory reasonable across all supported devices.
Should I use Restore mode or just Sharpen for old photos?
Restore is specifically tuned for faded printed photos: speckle suppression, then warmth and color revival, then sharpening — in that order. Sharpen mode alone skips the color revival and noise steps. For genuinely old or faded prints, Restore is the better starting point; try Sharpen only if the photo is soft but not color-faded.
Can Unblurry colorize black-and-white photos?
No. Unblurry enhances clarity, contrast, sharpness, and noise. It does not colorize grayscale images — that is a separate category of AI model not included in the app.
