AI Image Upscaler: Enlarge Photos up to 4× Online
Make a small photo big enough to print, crop, or show full screen. Facelab's AI image upscaler enlarges images 2×, 3×, or 4× and fills in the new pixels with real-looking detail instead of blocky squares. It runs in your desktop browser, and you can try it free.

How it works
Step 1
Upload Your Photo
Start from the original file, not a screenshot or a copy someone sent you in a chat.
Step 2
Choose 2×, 3×, or 4×
The window shows the original size and the output size in pixels. On very large photos, some scales are marked Too large here.
Step 3
Upscale and Download
Press Upscale Now, wait while the detail is rebuilt, then download the PNG.
Look at the result at full size: a preview that fits on your screen hides the exact detail you upscaled the photo for.

What Does an AI Image Upscaler Do Differently?
Traditional enlargement stretches the pixels you already have, so edges go soft or jagged. An AI image upscaler predicts the detail that should sit between the original pixels and draws it in at the new size. At 4×, a photo 1,000 pixels wide becomes 4,000 pixels wide, with hair and fabric texture drawn in rather than stretched.
Check Faces First
People notice a wrong eyelid long before they notice a wrong brick. After you upscale a portrait, zoom in on the eyes and the outline of the face. If the face still looks like the person, the rest of the image usually does too.
Bring Old and Scanned Photos Back to Size
Old prints, small scans, and files from early digital cameras are often only a few hundred pixels across. Upscale them, and they're ready for a photo book, a framed copy, or a slideshow. Scan the print at your scanner's highest resolution first, because the upscaler can only build on what the scan captured.
Know What an AI Upscale Can and Cannot Do
An AI upscale adds detail by predicting it. That works well on skin, hair, and fabric. Small text, logos, and distant faces are harder, because the upscaler has to guess what the original never recorded. Compare them with the original before you use the result anywhere official. Don't upscale a file that's already been upscaled: go back to the original. If you need a different width or aspect ratio, use Resizing Image. For faded or yellowed scans, fix the colors with Photo Color Correction.
How Big Can You Print After You Upscale?
Most print shops recommend around 300 pixels per inch for photos you'll look at up close. Divide the width in pixels by 300 to get the largest sharp print width:
- 800 pixels: about 2.7 in (6.8 cm), or 10.7 in (27 cm) after a 4× upscale
- 1,000 pixels: about 3.3 in (8.5 cm), or 13.3 in (34 cm) after a 4× upscale
- 1,500 pixels: about 5 in (12.7 cm), or 20 in (51 cm) after a 4× upscale
An A3 print needs roughly 3,500 by 5,000 pixels, so a 900 by 1,250 pixel photo gets there at 4×. Do the math before you order.
AI Image Upscaler: Frequently Asked Questions
How much you can enlarge a photo, what you need to run the upscaler, and what to expect from the result.
How much can I enlarge a photo?
2×, 3×, or 4×. The window shows the output size in pixels before you start. Very large photos can't use every scale.
Does it work on my phone?
No. The upscaler needs a desktop browser with WebGPU, such as Chrome. In Safari, WebGPU may be turned off.
How long does it take?
It depends on the size of the photo and your computer. The time left is shown on screen while it works.
Will the upscaled photo look exactly like the original?
Not exactly. The new detail is predicted, so fine text, logos, and small faces can differ from the original. Compare them at full size.
What file do I get?
A PNG at the scale you chose. The download button shows the scale and size in pixels.
Can it fix colors or scratches on old photos?
No, it only enlarges. For faded colors, use Photo Color Correction.
Is the image upscaler free?
You can try it free.
