Frequently Asked Questions

What is the difference between image resizing and cropping?

Resizing scales the entire image smaller or larger without cutting anything off. Cropping cuts out a specific region of the image and discards the rest.

What does Lock Ratio do?

Lock Ratio (Aspect Ratio Lock) automatically calculates the proportional height when you change the width (or vice versa), preventing your photo from looking stretched or squished.

Can I resize images for YouTube thumbnails or Instagram?

Yes. Click the built-in social presets like 'YouTube Thumbnail (1280×720)' or 'Instagram Square (1080×1080)' for instant dimensioning.
