Questions & answers

Frequently asked

Does resizing make the image blurry?

Downscaling uses bicubic interpolation which is sharp and clean. Upscaling beyond the original resolution will always produce some softness. No software can add detail that was not there.

Can I resize animated GIFs?

Only the first frame of a GIF is processed. For animated GIFs, use dedicated animation tools.
