Frequently Asked Questions

I need a square image for Instagram. Can this tool help?

Absolutely! The 1:1 aspect ratio is perfect for Instagram posts. Just select 1:1 and choose the 'fit' option to keep your image looking great without distortion.

My YouTube videos look best with widescreen. What aspect ratio should I use?

For a classic widescreen YouTube look, the 16:9 aspect ratio is your best bet. It's the standard for most YouTube videos.

What's the difference between 'fit' and 'stretch'?

'Fit' keeps your image's original proportions – you might see white space around the edges to fill the new dimensions. 'Stretch' fills the entire new area, potentially distorting your image. Choose 'fit' for quality, and 'stretch' when filling the space is the priority.

I'm creating vertical videos for TikTok. Which aspect ratio is right?

TikTok thrives on vertical content! Select the 9:16 aspect ratio to make sure your thumbnails are perfectly sized for the platform.

Can I use this tool to resize images for other social media platforms?

Yes! While great for YouTube thumbnails, this tool works for any image you need to resize to a specific aspect ratio – Facebook, Twitter, presentations, you name it.
