ImgTools Image Upscale lets you choose between standard high-quality interpolation and AI enhancement. AI enhancement also runs in your browser, so images are not uploaded to the ImgTools server.
Choose the scale that fits your needs and apply the same scale to multiple selected images.
Quickly enlarges images using high-quality browser interpolation. Best when you simply need larger dimensions.
Uses a lightweight ESRGAN model for browsers to enhance edges and details while upscaling. Results vary by image content.
How to Use
- Select the images you want to upscale.
- Choose 2x, 3x, or 4x, then select “High-Quality Enlargement” or “AI Enhancement.”
- Click “Upscale and Download” to download the processed images as a ZIP.
About AI Enhancement
AI enhancement uses TensorFlow.js, UpscalerJS, and a browser-oriented ESRGAN Slim model. WebGPU is preferred when available; otherwise processing automatically falls back to WebGL or another supported backend.
AI estimates and generates details that may not exist in the original, so text and fine patterns may look different from the source image.
Supported Image Formats
Supports JPG / JPEG / PNG / WebP. The output format matches the original image format.
