Frequently asked questions
Can I keep the aspect ratio?
Yes — lock the ratio so changing the width updates the height automatically and avoids distortion.
Resize by pixels or percentage?
Either — set exact pixel dimensions or scale by a percentage.
Will enlarging blur my image?
Upscaling can soften detail because pixels are interpolated. For best results resize down rather than up.
