Frequently Asked Questions

What image formats can I upload?

You can upload PNG, JPG, WebP, GIF, and BMP images. The tool accepts any image format supported by your browser, ensuring maximum compatibility with your existing files.

What is the maximum image size?

There is no hard limit, but very large images (over 8000px) may be slower to process depending on your device's capabilities. The tool processes everything locally in your browser, so performance depends on your device's RAM and processing power.

How do I crop a circle image?

Click the Circle button in the toolbar. The crop area will become circular with a 1:1 ratio. The output is automatically saved as PNG with a transparent background, perfect for profile pictures and avatars.

Can I set a custom aspect ratio?

Yes. Click the Ratio button, then enter your desired width and height values in the custom ratio fields at the bottom of the dropdown, and click the apply button. This allows you to create crops with any specific dimensions you need.

What format should I choose for export?

PNG — Best for images with transparency, screenshots, and graphics. Lossless quality but larger file size
JPEG — Best for photographs. Smaller file size with adjustable quality (ideal for web use)
WebP — Modern format with excellent compression. Smaller than both PNG and JPEG at similar quality (best overall choice for web)

Are my images uploaded to a server?

No. All image processing happens entirely in your browser using client-side JavaScript. Your images never leave your device, ensuring complete privacy and security. No server uploads, no data collection, no tracking.

What are the guide lines for?

The guide lines show the Rule of Thirds grid, a professional photography composition technique. Placing key elements along these lines or at their intersections often creates more visually appealing and balanced images. This is widely used by photographers and designers to improve composition.
