Image Upscaler & Enhancer
Enlarge images with interpolation and sharpening
The essentials
The Image Upscaler enlarges small photos and graphics 2x or 4x using interpolation plus sharpening, restoring crispness for prints, slides, and large displays.
How to use it
- Upload a small or low-resolution image.
- Choose an enlargement factor and sharpening strength.
- Preview and download the larger image.
Pro tips
- Start with 2x — moderate enlargement looks the most natural.
- Add light sharpening to restore edge definition.
- Clean, sharp originals upscale far better than noisy or blurry ones.
Behind the result
Upscaling redraws the image at 2x or 4x using smooth interpolation, then applies a controllable sharpening pass to restore edge definition. It is honest interpolation, not cloud AI — instant and fully private.
