Using a Sobel edge-detection convolution, this tool isolates the contours of a photo and discards flat areas, producing a pencil-sketch or line-art style result.

پرسش‌های متداول

Does this permanently change my original file?

No. The effect is applied to a copy rendered in your browser. Your original image on disk is never touched — you download a new file with the effect applied.

Can I adjust the intensity before downloading?

Yes. Every slider updates the preview in real time, so you can fine-tune the effect before exporting the final image.

What format is the downloaded file?

PNG, to preserve full quality and, where relevant, transparency.
