About the Photo to Sketch
Photo to Sketch turns a photograph into a drawing in your browser. Pick a pencil sketch, a colour pencil version or bold ink lines, then adjust how thick the lines are and how dark the shading is while the picture updates. It works by finding the edges in your photo and drawing them as pencil strokes on white paper, the same way many photo editors make a sketch effect. Portraits, pets, buildings and landscapes all work. Your photo stays on your device and is never uploaded.

How the sketch effect works
A pencil sketch shows edges and shading, not colour. The tool starts from a grey copy of your photo, inverts it and blurs it. When that blurred negative is divided into the original, areas that change slowly come out white and areas that change quickly, the edges, come out dark. The blur size decides how wide the lines are.
Pick the right photo
Light and contrast matter more than resolution. A portrait lit from the side gives strong shading. A photo with a busy background will produce busy lines, so crop it first with Crop Image or pick a plain background. Pictures with large flat areas, such as a sky, come out as clean white paper.
- Use photos with clear subjects and good light
- Crop away clutter before converting
- Avoid very dark or very blurry photos
- Try several line thickness values
Choosing a style
Pencil is the classic look, with soft grey tones. Colour pencil adds a gentle wash of your photo's colours. Ink lines gives a high contrast outline that suits logos, posters and colouring pages, especially at a lower darkness value.
Use the result
Print the sketch as a colouring page, use it as a profile picture or turn it into a card. For a black and white look without the pencil effect, try Black and White Image. To change the size, use the Image Resizer, and Compress Image keeps the file small for sharing.
Tips for better sketches
If the result is too faint, increase the darkness. If the lines look broken, lower the line thickness. For a drawing that looks hand-made, convert at a medium thickness, then add handwriting or a caption with Add Text to Image.

Frequently asked questions
How does a photo become a sketch?
The tool makes a grey copy of your photo, blurs an inverted version of it and blends the two with a colour dodge. Smooth areas turn white and edges stay dark, which looks like pencil lines on paper.
Which photos work best?
Clear photos with good light and a plain or simple background. Portraits, pets, buildings and objects with strong edges give the nicest results. Very dark or blurry photos produce faint sketches.
What does line thickness do?
Low values draw thin, detailed lines, like a sharp pencil. High values spread the shading, which looks more like soft charcoal. Try the middle first, then change it.
What is the difference between Pencil and Ink lines?
Pencil keeps soft grey shading. Ink lines turns every pixel black or white, so you get a graphic outline drawing without grey.
Does it keep the colours?
The Colour pencil style keeps a faint tint of your photo's colours under the lines. Pencil and Ink lines are black and white.
Is there a size limit?
Large photos are scaled down to 1800 pixels on the long side so the page stays fast, even on phones. That is enough for screens and normal prints.
Can I use the sketch commercially?
The sketch is made from your photo, so you need the rights to the photo. If you took it yourself, you can use the result freely.
Is my photo uploaded?
No. The photo is processed on your device, and nothing is sent to a server.
