Haeufig Gestellte Fragen
Will resizing reduce quality?
Upscaling (making larger) always reduces quality. Downscaling preserves quality well. For best results, start with the highest resolution source image.
Does it maintain aspect ratio?
Yes, by default. You can toggle aspect ratio lock off to set custom width and height independently, but this may stretch or squash the image.
What output format is used?
The resized image is downloaded as PNG by default, preserving transparency. This works well for web graphics and screenshots.
