Frequently Asked Questions
How do I stop the image from stretching?
Keep the aspect-ratio lock enabled and width and height adjust together, preserving proportions so nothing looks squashed.
Can I enlarge a small image?
Yes, but enlarging beyond the original resolution can look soft, since there's no extra detail to add. Downsizing always stays crisp.
What size should social media images be?
Common sizes are 1080×1080 px for Instagram posts, 1280×720 px for YouTube thumbnails, and 1584×396 px for LinkedIn banners.
Are my images uploaded?
No — resizing happens entirely in your browser and nothing is sent to a server.
