Frequently Asked Questions

What is an image resizer?

It's a tool that changes an image's width and height in pixels. Ours runs entirely in your browser for speed and privacy.

Can I resize a photo for social media?

Yes — common sizes: Instagram square 1080×1080, Facebook cover 820×312, Twitter header 1500×500, LinkedIn banner 1584×396. Just enter them.

How do I resize without distortion?

Keep 'Maintain Aspect Ratio' on. It locks the width-to-height ratio so the image won't stretch. It's on by default.

Is there a limit on how many I can resize?

No. Processing is local, so you can resize as many images as you like.
