Frequently Asked Questions

An auto crop tool automatically detects solid-colored borders (like white or transparent margins) around your image and removes them, saving you from manual cropping.

The tool scans the pixels from each edge inward, stopping when it finds a pixel that differs from the chosen border color (by more than the tolerance). Everything outside that boundary is trimmed off.

No. All processing happens directly inside your browser using JavaScript and the Canvas API. Your image never leaves your device.

JPG, PNG, WEBP, BMP, and GIF. For best results with transparent borders, use PNG or WEBP. The cropped result is always downloaded as a high-quality PNG to preserve any transparency.

Yes! Use the "Border Color" dropdown to select White/Transparent, Black, or a custom color. The tool will then crop that specific color (and similar shades within the tolerance).

Tolerance controls how strictly the tool matches the border color. A lower value removes only exact matches; a higher value allows slight variations (e.g., off-white, shadows) to be treated as part of the border.

No. The cropped area is extracted at full original resolution. You get a perfect 1:1 copy of that portion without any recompression or quality loss (saved as lossless PNG).

If the tool doesn't detect any border matching your settings (e.g., the image already has content touching all edges), the cropped version will be identical to the original.

Yes, completely free. There are no usage limits, watermarks, or hidden fees.

Absolutely. The interface is responsive and touch-friendly. You can upload, adjust settings, and download directly from your phone or tablet.
