Frequently asked questions

Redimensionar imagen FAQ

Will resizing make a small image sharper?

No. Enlarging creates more pixels but cannot recreate missing detail. Start with the largest clean source available.

How do I avoid stretching?

Leave the fixed-aspect-ratio control on. If the required shape is different, crop the image instead of forcing it into the new proportions.

Does ResizeWizard upload the image?

No. Supported images are resized locally with browser canvas APIs.
