How to upscale images without pixelation (2× & 4×)

Need a bigger version of a small image? Plain resizing makes it blurry. Upscaling with high-quality smoothing looks dramatically better — and it runs right in your browser.

How to upscale

• Open Image Upscaler
• Upload your image
• Pick 2× (recommended) or 4×
• Download the enlarged version

When it works best

• Icons and logos — 4× works great, edges stay crisp
• Photos — 2× looks clean; 4× gets soft
• Thumbnails — 2× is plenty for profile pictures

The honest caveat

This uses high-quality smoothing — not AI detail-invention. For real AI upscaling you'd need a dedicated service, but for most everyday needs, 2× smoothing looks professional.
