Pencil sketch your photo online

Turn photos into pencil sketches online. Upload a picture, adjust pencil shadow thickness, preview the drawing effect, and download PNG in your browser.

What is a pencil sketch effect?

A pencil sketch effect turns a photo into a drawing that looks sketched with graphite—emphasizing edges and tonal shading instead of full color. Upload a picture, set pencil shadow to control line thickness, preview the result, and download PNG. Processing uses grayscale conversion, invert, blur, and color dodge entirely in your browser.

Pencil sketch controls

One shadow slider to tune the drawing effect.

  1. Pencil shadow slider: Adjust line weight from fine detail to bold sketch shading.
  2. Automatic preview: See the pencil sketched photo update as you move the slider—no apply button.
  3. Grayscale pencil look: Output mimics graphite drawing with light paper tones.
  4. Edge emphasis: Color dodge blending highlights contours like hand-drawn strokes.
  5. PNG download: Save as pencil-sketch-image.png for sharing or printing.
  6. Client-side processing: Sketch runs in your browser—private and fast for single photos.

How to convert a photo to a pencil sketch

Four steps to a sketched image in the browser.

  1. Upload your photo: Drop or click in the input panel (15 MB max). Portraits and landscapes both work.
  2. Set pencil shadow: Increase shadow for softer, thicker lines; decrease for sharper pencil detail.
  3. Preview the sketch: Check shading and edges in the live preview before export.
  4. Download PNG: Save the pencil sketched photo to your device.

Tips for better pencil sketches

Sharper drawing results from your photos.

  1. Use clear subjects: Portraits with good contrast produce stronger pencil lines.
  2. Start mid shadow: Try shadow around 50, then nudge up or down for your photo.
  3. Avoid tiny uploads: Very small images may look flat—higher resolution gives finer strokes.
  4. Check the preview: Zoom the output panel mentally for lost detail before download.
  5. Pair with crop: Tighten composition on /crop-image before sketching for cleaner framing.
  6. Export PNG: PNG keeps smooth grayscale tones for screens and light printing.

When to sketch a photo
