Private image enlargement
Upscale Image Online
Enlarge an image to two, three, or four times its original width and height.
High-quality interpolation increases pixel dimensions but does not invent missing photographic detail.
How to use the image upscaler
- STEP 1Choose an image.
- STEP 2Select 2×, 3×, or 4× scaling.
- STEP 3Review the output dimensions and download the PNG.
About this tool
Increase pixel dimensions with high-quality interpolation and an explicit output-size safety limit.
A 2× scale creates four times as many total pixels; 4× creates sixteen times as many.
Use sharpening separately and conservatively if the enlarged result needs more perceived edge contrast.
Frequently asked questions
Does this use AI to invent detail?
No. It uses high-quality interpolation to increase dimensions while keeping the process private and predictable.
Why is output limited to 40 megapixels?
The limit reduces browser memory failures during full-resolution canvas rendering and PNG encoding.
Can upscaling fix a very blurry source?
No. Interpolation can smooth enlarged pixels but cannot recover detail absent from the original image.
