Free AI image upscaler

Upscale and sharpen images with AI right in your browser — your photos are never uploaded. Enlarge 2x or 4x to add resolution and detail, then download. Free, no watermark.

WHY USE IT

Features

100% free, in your browser

Upscale images with AI — no upload, no sign-up, no watermark.

Enlarge image 2× or 4× — up to 4K

Multiply resolution to make small images large and crisp; on desktop, 4× takes a 1080p photo past 4K.

AI detail, not just stretch

A neural model reconstructs edges and texture instead of blurring.

Private by design

The model runs locally on your device — nothing is uploaded.

WHAT IT'S FOR

Use cases

Enlarge for print

Add the pixels a photo needs to print bigger without pixelation.

Rescue small images

Bring low-resolution photos and logos back to a usable size.

Sharpen for display

Upscale thumbnails and old pictures for modern screens.

HOW IT WORKS

How to upscale an image with AI

01

Upload your image

Drop, paste or pick a JPG, PNG, WebP, HEIC, AVIF, TIFF, BMP, or TGA — it stays on your device.

02

Pick 2x or 4x

Choose how much to enlarge; the AI adds detail as it scales.

03

Download

Save your higher-resolution image in one click.

FAQ

Frequently asked questions

Yes — the in-browser upscaler is free, with no sign-up and no watermark.

No. The AI model runs locally in your browser; your photos never leave your device.

Choose 2x or 4x. Very large outputs are limited in the browser to stay stable; bigger jobs will move to a premium server tier.

The first run downloads the AI model. After that it is cached and later images are faster, especially on devices with WebGPU.

JPG, PNG, WebP, HEIC, AVIF, TIFF, BMP, and TGA input, up to 100MB per image.

Yes — on desktop, 4× on a 1080p image gives you 4K-class output (3840×2160 and larger). On phones the output is capped at 3000 px to keep the browser stable; for bigger jobs use the Pro enhancer, which runs on our servers and uses credits.
