Image Upscaler — Enlarge Photos 2x, 3x or 4x

Make a small image bigger without the blocky, blurry look of a simple stretch. This upscaler enlarges in 2x steps with high-quality resampling, then applies an unsharp mask to restore edge contrast.

How to upscale an image

1. Drop your image in.
2. Choose the scale — 1.5x, 2x, 3x or 4x — and the output format.
3. Adjust Sharpen (60% is a good default; lower it for faces and skin, raise it for text and line art).
4. Press Upscale, compare, and Download.

No watermark, no sign-up, and no upload: everything runs on your device.

What to expect — honestly

This is classical resampling, not AI. It makes an image larger and crisper, but it can't invent detail that was never captured. It works well for:

• Screenshots and graphics that need to be bigger for a slide or document
• Logos and icons (use PNG output to keep transparency)
• Photos going up one size step, e.g. 1000 px → 2000 px for a print
• Preparing small text for OCR, which reads larger text more accurately

It won't turn a 200-pixel thumbnail into a sharp poster, fix motion blur, or restore faces.

AI upscaling vs resampling

AI upscalers are trained on millions of image pairs and predict plausible detail — hair texture, fabric, foliage. For old family photos, product shots and anything headed for print, the difference is dramatic.

Upscale Studio runs four AI super-resolution models entirely on your PC: 2x, 3x or 4x, whole folders at a time, with transparent PNGs kept crisp and GPS stripped from the output. No upload queue, no credits, no subscription.

Size limits

Browsers cap canvas size, so output is limited to about 36 megapixels (e.g. 6000 × 6000). If you hit the limit, choose a smaller factor.
