Frequently Asked Questions

Is this tool completely free?

Yes! RealMultiTool is completely free. There are no hidden fees, watermarks, or daily usage limits.

Do you store my images on your servers?

No. Everything runs purely on the frontend using your browser's processing power. Your files never leave your device, ensuring maximum privacy.

What is aspect ratio?

Aspect ratio is the proportional relationship between an image's width and height. Keeping the "Lock Aspect Ratio" box checked ensures your image doesn't look stretched or squished when you resize it.

Why did my file size increase?

If you convert a highly compressed JPEG into a PNG, the file size may increase because PNG is a lossless format. Stick to JPEG or WebP for the smallest file sizes.
