AI image upscaler
AI Image Upscaler Free: Enlarge Photos 2× or 4× Without Blur
Small images look blurry when enlarged the normal way, because pixels are just stretched.
An AI upscaler predicts the missing detail, so enlarged photos stay crisp.
How to upscale
- Open the AI image upscaler.
- Drop an image (JPG, PNG, WEBP, HEIC and more).
- Choose 2× or 4×.
- Adjust AI detail (lower for softer, natural faces).
- Click Upscale with AI and download.
Compare before saving
The preview shows normal enlargement on the left and AI on the right.
Good uses
- Small supplier photos that need 1000–2000 px for listings.
- Logos that print blurry.
- Old photos and scans.
- Thumbnails that need to be larger for banners.
Choose the right format
PNG keeps the most detail and is best for further editing. JPG makes smaller files for uploads. WEBP is ideal for websites.
AI detail setting
AI detail controls how strongly new detail is added. 100% gives the sharpest look for products, text and logos. For portraits, lower it so skin looks natural rather than over-sharpened. Compare left and right in the preview before downloading.
Upscale, then finish
After upscaling, resize to an exact listing size, remove the background if needed and compress to the upload limit. Doing these steps in that order keeps the most detail in the final image.
Best results
- Start from the best original you have.
- Use 2× for good images, 4× for very small ones.
- Save PNG for best quality.
