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.
