Frequently Asked Questions
What happens if I don't maintain aspect ratio?
If you disable 'Maintain Aspect Ratio', you can set custom width and height independently. This may stretch or squash your image if the proportions don't match the original.
How much can I reduce file size?
File size reduction depends on the quality setting and resolution. Lower quality (60-80%) can reduce file size by 50-70% while maintaining acceptable visual quality for web use.
Can I resize images for Instagram or social media?
Yes! You can resize images to exact dimensions required by any social media platform. Common sizes include 1080x1080 for Instagram posts, 1200x628 for Facebook, etc.
