Welcome to the Image Upscaler tool by SpeedyUtils – a completely free, browser-based image enhancement utility that allows you to upscale your images by 2x or 4x without losing quality. Whether you're working with pixelated photos, blurry screenshots, or low-resolution graphics, this tool brings AI-powered super-resolution to your fingertips.
An image upscaler is a tool that increases the resolution of a photo or image, making it appear sharper and more detailed. Traditional upscaling techniques simply stretch pixels, which often leads to blurry or pixelated results. However, with the advent of AI and deep learning, image upscaling has reached new heights of precision and realism.
Our tool uses the ESRGAN (Enhanced Super-Resolution Generative Adversarial Networks) models – a powerful AI model trained to enhance photo details by reconstructing finer textures and removing noise.
Unlike many upscalers that require software installation, payments, or login, this tool works entirely in your browser and is:
No sign-up, no waiting, no hassle. Just upload your image, select a scale, and download the enhanced result.
This tool leverages Upscaler.js, an open-source browser library that integrates TensorFlow.js and pretrained ESRGAN models to upscale images in real-time. Here's a simplified flow of how it works:
Since this tool runs entirely in your browser, no images are sent to a server – perfect for private or sensitive photo enhancement.
Achieve state-of-the-art results using machine learning models trained on thousands of image samples.
Everything runs in your browser. No uploads, no delays, no privacy risks.
Choose between fast upscaling with 2x or higher-quality upscaling with 4x ESRGAN Slim models.
Works across Chrome, Firefox, Edge, Safari, and even mobile browsers.
Quickly drag your photo or select it using the file browser. Preview both original and upscaled versions.
Compare original and enhanced images interactively to see the improvements in real-time.
This upscaler is ideal for:
The use of ESRGAN Slim models allows for high-quality upscaling with reduced computational cost, making it ideal for in-browser use cases.
We never send your files to any server. All processing is done locally in your browser using WebGL, which means:
This makes our upscaler one of the most secure solutions on the internet for image enhancement.
