Frequently Asked Questions
Everything you need to know about processing files securely in your browser
How do I crop an image locally in my browser?

Can I crop images to standard aspect ratios?

What file formats are exported?
You can choose to export your cropped image in PNG or JPEG format, saving it directly to your downloads.
