Tips
Social media posts work best with square (1:1) or landscape (16:9) ratios, as portrait images may appear smaller.
Instagram Stories work best with 9:16 vertical ratio, optimized for mobile viewing.
Blog thumbnail images are typically 1200x630px and also work well for Facebook sharing.
Making images too small reduces quality, while making them too large increases loading time.
Transparent PNGs are perfect for logos and icons, but some social media platforms may display them with black or white backgrounds.
FAQ

How does the aspect ratio lock work?
When aspect ratio lock is ON, changing width or height automatically adjusts the other dimension proportionally.

What does 'Keep Original Aspect Ratio' do?
When enabled, the original image proportions are preserved and empty space is filled with the specified background color or transparency. This prevents image distortion.
