Frequently Asked Questions
Is this image resizer free?
Yes, our image resizer is completely free to use. There are no hidden fees, no watermarks, and no registration required.
Will resizing reduce image quality?
Resizing to a smaller size generally maintains quality well. When enlarging images, some quality loss may occur as the software needs to interpolate new pixels.
Is my image secure?
Absolutely. All processing happens directly in your web browser. Your images are never uploaded to our servers - they stay on your device.
What's the maximum image size I can resize?
Since processing happens in your browser, the limit depends on your device's memory. Most devices can handle images up to 10,000 x 10,000 pixels without issues.
What does "lock aspect ratio" mean?
Aspect ratio is the proportional relationship between width and height. When locked, changing one dimension automatically adjusts the other to prevent distortion.
