Frequently Asked Questions

What does "Maintain Aspect Ratio" mean?

Aspect ratio is the proportional relationship between the width and height of an image. If you maintain it, changing the width will automatically adjust the height so that your image doesn't look distorted.

Will resizing an image reduce its file size?

Yes, reducing the physical dimensions (width and height) of an image significantly reduces the total number of pixels, which in turn results in a smaller file size in megabytes (MB) or kilobytes (KB).

Can I enlarge a small image?

While you can enter dimensions larger than your original image, doing so is called "upscaling." Upscaling typically results in a blurry or pixelated image because the browser has to invent new pixels to fill the larger space.
