Does cropping reduce image quality?

No. Cropped images are exported as PNG —a lossless format. Every pixel in your crop is preserved with zero quality loss.

Can I use custom aspect ratios?

Yes. You can choose from preset ratios (1:1, 4:3, 16:9, 3:2, etc.) or use free crop mode to select any area without ratio constraints.

Are my images uploaded to a server?

No. All cropping happens entirely in your browser using the HTML5 Canvas API. Your images are never uploaded anywhere and the tool works offline once loaded.

What file formats are supported?

The tool supports JPG, PNG, WebP, BMP, and GIF input formats. Output is always a high-quality PNG file.

Can I crop images larger than the screen?

Yes. Images are scaled to fit the viewport for editing, but the final crop is rendered at full original resolution using the Canvas API.
