Frequently Asked Questions
How do I resize without distorting?
Enable Lock Aspect Ratio before changing dimensions. Width changes will automatically adjust height proportionally.
Can I make an image smaller to reduce file size?
Yes. Reducing dimensions reduces file size significantly. Also lower quality and consider WEBP for additional savings.
Can I upscale an image?
Yes, but enlarging beyond original size reduces sharpness. For best results only downscale.
Are images uploaded?
No. All resizing uses the HTML5 Canvas API in your browser.
