What is the 1:1 aspect ratio used for?

Instagram posts, profile pictures, product thumbnails, app icons, album covers

What are the recommended 1:1 dimensions?

For 1:1, we recommend 1080×1080px for optimal quality. The crop tool lets you enter custom dimensions if you need a different size.

Does cropping reduce image quality?

No. Our crop tool extracts pixels directly without recompression, so there is zero quality loss.

Are my images uploaded to a server?

No. All cropping happens locally in your browser using the Canvas API. Your images never leave your device.

Can I crop to a custom size?

Yes! While we offer the preset, you can enter any custom X, Y, width, and height values for precise control.

Does it work on mobile?

Yes! The crop tool is fully responsive and works on any modern smartphone or tablet browser.
