Upscale an image to twice its resolution
A photo saved from WhatsApp, an old 640-pixel picture or a small logo looks soft when you print it or show it on a big screen. Here the image is enlarged to twice its width and height with resampling that keeps edges clean, and you can sharpen it on top.
How to use it
- Choose the image.
- “Double resolution (2× crisp)” is already ticked. Adjust “Sharpness / Focus”, “Clarity” and “Light & shadows” to taste.
- Tap “Enhance photo” and download the enlarged image.
What 2× really does
The image goes from, say, 800 × 600 to 1600 × 1200 pixels: four times as many pixels. The new pixels are calculated from the ones around them with a smoothing filter and then sharpened, so edges and text stay crisp instead of blocky. It is not generative AI: it can’t invent a face, hair or lettering that wasn’t in the original. A blurry photo becomes a larger, cleaner-edged blurry photo, not a sharp one.
When it is worth it
Small photos for printing (a 1000-pixel photo prints well at 10 × 15 cm after doubling), screenshots to show on a slide, old low-resolution pictures and profile photos that a site displays larger than they are. For a photo that is already 12 megapixels, doubling only makes the file bigger: use the sharpening sliders with the 2× option off instead.
Questions and answers
Can I upscale 4× or to an exact size?
The tool doubles once. For an exact size, set the pixels with resize image afterwards; running the 2× twice adds no real detail.
What is the difference from “enhance photo quality”?
Enhance photo quality is the same tool with the 2× option off: it sharpens and recovers light at the original size. This page starts with the doubling enabled.
Does it fix pixelated images?
It smooths the blocks and sharpens the edges, so a pixelated image looks cleaner, but the missing detail can’t be recovered.
Are my photos uploaded to a server?
No. Everything is processed inside your browser, on your own phone or computer. Your photos never leave your device and nobody else can see them.
