FAQ

Frequently Asked Questions About Resizing Images

Everything you need to know about file privacy, technical limits, and in-browser processing.

Will resizing distort my photo’s proportions?
No. As long as the "Maintain Aspect Ratio" lock is checked, changing the width automatically updates height proportionally.
Can I enlarge a small image?
Yes, but enlarging raster images beyond their original resolution can reduce sharpness. Resizing downward produces the cleanest results.
Can I resize by percentage instead of exact pixels?
Yes. Quick preset buttons allow scaling to 25%, 50%, or 75% of original dimensions in one click.
Are my images stored on your servers?
No. All image scaling takes place inside your browser’s local memory with zero server uploads.
What output formats are supported?
You can save your resized image in its original format or convert to JPG, PNG, or WebP.
