Image Upscaler – Batch Upscale to 4K/8K (x4–x16)

Image Upscaler is a desktop app that increases the resolution and sharpness of your images, from a single file to a whole folder of them.

Instead of upscaling one image at a time, just turn on Batch Upscale, point it at the folder of images to process, set the quality you want and press Upscale. The app works through every image automatically and saves the results to the output folder you chose.

You can set the upscale level to fit your need — from x4 up to x16 — or export at high resolutions like 4K and 8K.

Key features

• Batch-upscale a whole folder in one run
• Process every image in a folder automatically

• Export at high resolution such as 4K and 8K
• Choose your own output folder
• Runs the whole list after one press of Upscale
• Simple interface, friendly to beginners
• A desktop app installed directly on your computer

How to use

Step 1 — Open the app

Install and open Image Upscaler on your computer. From the main screen you can upscale one image or switch to batch processing.

Step 2 — Turn on Batch Upscale

To upscale many images at once, switch Batch Upscale — ON. With it on, the app lets you pick a whole folder of images to process automatically. With it off, you pick a single image to upscale — handy for a quick one-off.

Step 3 — Choose the image or folder

With Batch Upscale on, choose the folder that holds all the images to upscale; the app uses every image inside as its input list. With Batch off, pick one image directly.

Step 4 — Choose the upscale level

Set the output quality: x4, x8, x16, 4K or 8K. Higher levels mean larger output resolution and can take longer. For images used on a website or social media, you don't have to pick the highest level.
