How to Use the AI Image Upscaler – Free Online Tool by RHRnet

In today’s digital world, high-quality images are more important than ever. Whether you are a blogger, photographer, designer, or business owner, having sharp and detailed images helps you stand out. But sometimes the images we capture or download are too small, blurry, or pixelated. That’s where an AI Image Upscaler comes to the rescue.

At RHRnet - Free Online Tools, we provide a free AI Image Upscaler that lets you enlarge and enhance images directly in your browser. Unlike many other tools, this one does not require uploading files to external servers — everything happens locally on your device. That means your images remain private, secure, and fast to process.

In this guide, you’ll learn exactly how to use the AI Image Upscaler step by step, along with its key features, benefits, and FAQs.

Key Features of RHRnet AI Image Upscaler

Before diving into the step-by-step process, let’s highlight the main features:

• Completely Free – No subscriptions or hidden charges.

• Local Processing – Your images never leave your device.

• Multiple File Formats Supported – JPG, PNG, WEBP, BMP, and HEIC.

• Batch Upload – Process up to 5 images at a time.

• Two Enlargement Options – 200% and 400%.

• Fast Results – Most modern devices process images in under 10 seconds.

• High Privacy – No data stored on external servers.

Now let’s go through the step-by-step guide.

Step 1: Upload Your Images

You can upload images in two ways:

1. Drag and Drop – Just drag your image files from your computer and drop them inside the dashed upload box.

2. Browse Files – Click the “Browse Files” button, select the images from your computer, and click Open.

👉 Supported formats include: JPG, PNG, WEBP, BMP, and HEIC (though HEIC support depends on your browser).
👉 You can upload up to 5 images at once.

This makes it convenient for batch processing, whether you’re enhancing product images for your store or personal photos.

Step 2: Review Your Uploaded Files

Once uploaded, you’ll see a preview for each file showing:

• Image Thumbnail

• File Name

• File Size

• Original Dimensions

If you change your mind about an image, simply remove it by clicking the circular X button next to its details.

This review step ensures that you only upscale the images you really want.

Step 3: Choose the Upscale Size

Our AI Upscaler offers two enlargement options:

• 200% (2x enlargement) – Doubles the dimensions of the original image.

• 400% (4x enlargement) – Quadruples the dimensions.

By default, the tool selects 400% for maximum enhancement. However, if you only need a smaller enlargement (for faster results or less file size), 200% is a great choice.

Step 4: Start the Upscaling Process

Once you’ve reviewed and selected your options, click the orange “Start Upscaling” button.

• A progress bar will appear for each image.

• The process usually takes less than 10 seconds per image on modern computers.

• All processing is powered by AI locally — no uploads, no waiting for servers.

This makes the process both fast and secure.

Step 5: Download Your Enhanced Images

After processing is complete, the preview area updates to show:

• New dimensions

• Updated file size

You’ll also see a green “Download” button next to each image. Click it to save your enhanced, high-resolution image directly to your device.
