Frequently Asked Questions

Will resizing reduce image quality?

Resizing to smaller dimensions typically maintains good quality. When enlarging images, some quality loss may occur as the image is being stretched. For best results, resize to dimensions smaller than or equal to the original.

What does "maintain aspect ratio" mean?

Aspect ratio is the proportional relationship between width and height. When enabled, the image maintains its original proportions, preventing distortion. The tool automatically adjusts the other dimension to preserve the ratio.

Can I resize multiple images at once?

Yes! Our tool supports batch processing. Upload multiple images and they'll all be resized to the same dimensions in one operation.

Which output format should I choose?

Choose JPEG for photographs and general use, PNG for images requiring transparency, and WebP for best compression and web use. WebP files are smaller but may not be supported by older software.

Is my data secure?

Absolutely. All image processing happens entirely in your browser. Your images are never uploaded to any server, ensuring complete privacy and security.
