What is the UpScale Image Upscaler?
UpScale is a free, browser-based bulk image upscaler that enlarges your images up to 8× their original resolution without uploading a single file to any server.
All processing happens locally using the HTML5 Canvas API, so your images stay on your device. It is useful for e-commerce product photos, blog images, social media creatives, and print preparation.
You can upscale multiple images in one go, choose PNG, JPEG, or WebP, and optionally apply sharpening for crisper edges after scaling.
