Can I crop transparent PNGs?

Yes. Alpha transparency channels are completely preserved.

Is my photo uploaded anywhere?

No. Cropping executes locally inside your web browser canvas.

Can I rotate the image before cropping?

Yes. You can rotate and straighten crooked photos before adjusting your final crop boundaries.

Does cropping retain color profiles (sRGB / Display P3)?

Yes. The canvas preserves color profiles to ensure skin tones and brand hues stay accurate.

How does client-side cropping maintain color profile accuracy?

The HTML5 2D Canvas context preserves the embedded sRGB and Display P3 color space gamuts, ensuring that cropped portraits and product images retain true color balance.

What is Image Cropper?

Image Cropper provides an intuitive, high-precision cropping canvas to trim unwanted borders, adjust visual framing, and fit photos into specific aspect ratio containers (such as 16:9 widescreen, 4:3 standard, 1:1 square, or 9:16 mobile story).

Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.
