Professional Image Upscaling Without Quality Loss

The Online Image Enlarger by ImageResizze is designed to solve the common problem of pixelation when increasing photo sizes. Standard resizing tools simply stretch existing pixels, leading to a blurry, "jagged" look. Our tool uses advanced AI-inspired interpolation to intelligently fill in missing data, ensuring your images stay sharp even at 400% magnification.

Why Use Our Privacy-Focused Upscaler?

Most upscaling services require you to upload your files to their cloud servers. At ImageResizze, we prioritize your data security. Our enlarger works 100% client-side. This means the high-resolution processing happens inside your browser's memory. Your personal photos or company assets never leave your computer, making it the most secure way to enhance images online.

Perfect for Printing and Web Design

Whether you need to turn a small web graphic into a print-ready asset or improve the quality of an old family photograph, our tool delivers. By using our 4x Scale option, you can significantly increase the DPI of your images, making them suitable for physical prints, posters, and professional presentations without the typical loss of detail.

Frequently Asked Questions

How does this enlarger maintain quality?

We use a high-quality lanczos-style interpolation and sharpening filters. This analyzes neighboring pixels to predict what the new pixels should look like, resulting in smoother gradients and sharper edges than standard resizing.

Is there a limit to image size?

For the best performance, we recommend uploading images under 10MB. Since the processing happens in your browser, larger images may require more RAM on your device.

Is this tool free to use?

Yes! ImageResizze offers all tools for free with no hidden watermarks or subscriptions. You can enlarge as many images as you need.

Can I enlarge low-quality screenshots?

Yes. Our tool is excellent for making screenshots more readable and professional by increasing the resolution and smoothing out the digital noise.

What formats do you support?

We fully support JPG, PNG, and WebP. For PNG files, transparency is preserved during the enlargement process.
