Frequently Asked Questions

Will resizing an image reduce its file size?

Yes. Downscaling dimensions significantly decreases the total number of pixels, which usually causes a dramatic reduction in file size.

Can I enlarge an image without pixelation?

While upscaling adds interpolated pixels, our tool uses high-quality bicubic smoothing to keep edges as clean as possible.
