A pencil sketch effect strips a photograph down to the lines and shading a graphite drawing would capture — flat, evenly-lit areas fade to white “paper,” while edges and tonal shifts surface as soft pencil strokes. Image Machine builds the look entirely in your browser using the classic colour-dodge technique: the image is inverted, blurred, and blended back against itself so only the meaningful contours survive. Two sliders shape the result — softness sets how fine or broad the strokes are, and darkness controls their weight — and a style switch chooses between a monochrome graphite drawing and a coloured-pencil version that keeps the photo's original hues. Nothing is uploaded; your image is processed locally and you download the result instantly.

Frequently Asked Questions
How do I turn a photo into a pencil sketch?
Upload any photo and Image Machine instantly renders it as a pencil drawing. Use the softness slider to make the lines finer or broader, the darkness slider to make the strokes lighter or heavier, and the style switch to choose graphite (grayscale) or coloured pencil. When you like the result, download it — there's no sign-up and no watermark.
What's the difference between graphite and coloured pencil?
Graphite produces a classic black-and-white sketch, as if drawn with a single pencil. Coloured pencil runs the same sketch process on each colour channel separately, so the strokes keep a tint of the photo's original colours — closer to a coloured-pencil illustration. You can switch between the two at any time and the preview updates live.
Will the sketch keep a transparent background?
Yes. Transparent areas of a PNG stay transparent — the sketch is drawn only where the image has visible pixels, so you get clean strokes on a transparent background you can place over any colour.
Is my image uploaded to a server?
No. The entire sketch is rendered in your browser with the HTML canvas, so your photo never leaves your device. It works offline once the page has loaded, with no sign-up, no watermark, and no quality loss from re-compression.
