Free AI Image Upscaler overview
Free AI Image Upscaler is a browser-based tool for enlarging and sharpening photos, screenshots, artwork, and other graphics. It uses local AI processing to upscale an image by 2×, with the stated goal of preserving clearer edges and textures than basic pixel stretching.
The workflow is designed for quick, private enhancement: choose a JPG, PNG, or WebP file, compare the original with the result, and download the enhanced version as a PNG. Files are processed on the device and are not uploaded to a server, while input files must stay within the 2048 × 2048 pixel and 20 MB limits.
Key features
Local browser processing
Runs the enhancement process locally in the browser, so photos and graphics remain on the user's device rather than being sent to a server.
Supported uploads
Accepts JPG, PNG, and WebP files up to 2048 × 2048 pixels and 20 MB.
Before-and-after comparison
Shows the original and enhanced images side by side, with zooming for closer inspection before saving.
PNG export
Downloads the processed image as a high-quality PNG for use in projects, posts, or print.
Quick, no-login workflow
Works without an app installation, login, or account creation, and processes most images in a few seconds depending on the device and file size.
