Preguntas Frecuentes

What's the maximum size I can resize to?

The limit depends on your browser and device memory. Most devices can handle images up to 8000×8000 pixels without issues.

Does resizing up reduce quality?

Yes. Enlarging an image beyond its original dimensions will introduce some blurriness since the tool must interpolate new pixels.

Can I resize without maintaining aspect ratio?

Yes! Uncheck the "Lock ratio" checkbox to set width and height independently. This will stretch or squeeze the image.
