Questions about upscale image
Is this AI upscaling?
No. It enlarges with high-quality smoothing, so a very small image will still look soft — it cannot invent detail.
Which formats work?
JPG, PNG and WebP. You get the same format back.
Is my image uploaded?
No. It is enlarged in your browser.
What upscaling can and cannot do
This tool enlarges a JPG, PNG or WebP by 2, 3 or 4 times with high-quality smoothing, and saves the result in the same format with the size added to the file name, such as photo-2x.png. Smoothing fills the extra pixels with sensible in-between values, but it cannot invent detail that was never captured. It is not AI super-resolution, so very small images will still look soft when enlarged.
The table shows the pixel sizes you get from common starting sizes.
| Original size | 2× | 3× | 4× |
|---|---|---|---|
| 640 × 480 | 1,280 × 960 | 1,920 × 1,440 | 2,560 × 1,920 |
| 800 × 600 | 1,600 × 1,200 | 2,400 × 1,800 | 3,200 × 2,400 |
| 1,280 × 720 | 2,560 × 1,440 | 3,840 × 2,160 | 5,120 × 2,880 |
| 1,920 × 1,080 | 3,840 × 2,160 | 5,760 × 3,240 | 7,680 × 4,320 |
Getting the best result
Start from the largest original you have, and avoid enlarging a picture that has already been compressed hard, because blocky compression marks get bigger too. A gentle 2× enlargement usually looks best; 4× works for graphics and screenshots but shows softness in photos.
For printing, aim for about 300 pixels per inch: an 8 × 10 inch print needs roughly 2,400 × 3,000 pixels. If the enlarged image is still short of that, print it smaller or retake the picture at a higher resolution. Very large results may exceed your browser’s memory, so try a smaller factor if the tool reports an error.
