What is the benefit of locking aspect ratio?

Aspect ratio is the proportional relationship between width and height. Keeping it locked ensures your image retains its natural look without stretching or squishing.

Can I resize photos for social media?

Yes! You can enter exact dimensions for Instagram (1080×1080), YouTube thumbnails (1280×720), Twitter/X banners (1500×500), and LinkedIn banners.

Are there any limits on file size or usage?

You can resize files up to 50MB with resolution up to 10,000 pixels. There are no daily limits, subscriptions, or watermarks.
