Locked: changing one dimension updates the other using the first image as a reference. Each batch image keeps its own aspect ratio.

Frequently asked questions
How do I resize without stretching?
Keep 'lock aspect ratio' on — changing width auto-adjusts height so nothing distorts.
Can I resize by percentage?
Yes — scale to 50%, 200%, or any percent for quick enlargements and reductions.
Does resizing reduce quality?
Downsizing is safe. Upsizing beyond the original adds softness — for big enlargements, keep it modest.
What sizes work for social media?
Common ones: 1080x1080 for Instagram posts, 1500x500 for X headers, 820x312 for Facebook covers. Type any dimensions you need.
Are my images uploaded?
Never. Resizing runs 100% in your browser on your own device.
Choose a common canvas size for social posts. The image will be centered and cropped, or fitted with padding, to reach the exact preset dimensions.
