Frequently Asked Questions
How do I crop an image online?
Upload your image, drag on the canvas to select the crop area, choose an aspect ratio if needed, and click Download. Everything happens in your browser — no server upload required.
What aspect ratios are available?
Free crop (any size), 1:1 (square), 4:3, 3:2, 16:9 (widescreen), 9:16 (portrait), 2:3, and a custom ratio option where you enter your own width:height values.
Is my image uploaded to a server?
No. All cropping is done locally in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy.
What image formats are supported?
PNG, JPG/JPEG, WebP, BMP, GIF, and SVG. The cropped result is downloaded as PNG by default, which preserves quality and transparency.
Can I set a custom crop size in pixels?
Yes. Select the 'Custom' ratio option and enter your desired width and height values. The crop area will snap to that aspect ratio as you drag.
How does the real-time preview work?
As you drag to create or adjust the crop area, the cropped preview panel updates instantly showing exactly what your final image will look like after cropping.
Can I rotate the image before cropping?
Yes, use the rotation buttons (↶ and ↷) to rotate the image 90° clockwise or counter-clockwise before making your crop selection.
Is there a file size limit?
The tool handles images up to ~50MB. Very large images may take a moment to load and render, but should work fine on modern browsers.
