Image Upscaler

Introduction

The "Online Image Upscaler" is a practical web application designed to help users increase image resolution. It's ideal for situations where you need to enlarge images while minimizing detail loss. This tool employs advanced image processing techniques that, while not perfect, effectively enhance image clarity in most cases. It's user-friendly and perfect for those unfamiliar with complex image editing software.

Each upscale costs 2 points, you can buy points here。

Instructions

1. Upload images, multiple upload methods supported:

① Computer screenshot → Windows (control + v), Mac (command + v);

② Local computer images → Click "Select Image" button to upload;

③ Mobile photos or instant captures → Scan QR code to upload from mobile.

2. Select scale factor: Choose different scale factors according to your needs. Note that higher scale factors may have a greater impact on image clarity.

3. Click the "Upscale" button to start processing. Processing time varies depending on image size and selected scale factor.

4. View results and right-click to save to your local computer.

How It Works

Based on deep learning super-resolution reconstruction method. This approach trains deep neural network models to learn the relationship between high-resolution and low-resolution image pairs. Based on this, the model can predict missing details in low-resolution images to generate high-resolution versions.

Compared to traditional image upscaling techniques, deep learning methods better preserve image details and textures, reducing common blur and distortion during upscaling. Moreover, with enriched training data and algorithm optimization, this technology continues to improve in both upscaling quality and speed.

This tool is suitable for basic image upscaling needs, but please note that any upscaling may result in some loss of clarity, so use it judiciously according to your needs.
