Frequently Asked Questions

How does the Batch Image Upscaler work?

Our tool uses advanced browser-based canvas rendering to enlarge your images. It employs high-quality interpolation algorithms (Bicubic-like) to maintain clarity and detail while increasing the dimensions of your photos. Everything happens right in your browser, ensuring maximum speed and quality.

Is it safe to upload my private photos?

Yes, it is 100% safe. Unlike other online tools, we don't upload your images to any server. All processing is done locally on your device using JavaScript. Your privacy is our priority, and your data never leaves your computer.

What is the maximum upscale limit?

You can upscale your images up to 1000% (10x) of their original size. For example, a 1000x1000 image can be enlarged to 10000x10000 pixels. We also provide an aspect ratio lock to ensure your images are never stretched or distorted during the process.

Can I process multiple images at once?

Absolutely! Our tool is built for batch processing. You can upload multiple files at once, apply your desired upscaling settings to all of them using 'Batch Mode', and download them all together in a convenient ZIP archive.

What image formats are supported?

We support most common web image formats including JPG, PNG, WEBP, and BMP. The processed images are exported with high-quality settings to ensure you get the best possible results for printing, web use, or professional design projects.
