Free Image Pencil Effect — Convert Photos to Pencil Sketches Online
Turn any photo into a pencil drawing with this free browser-based image effect tool. The pencil sketch filter detects edges in your image, converts colors to grayscale, and renders the result as stylized pencil strokes — giving any photograph the look of a hand-drawn sketch. Adjust the intensity to achieve anything from a subtle artistic touch to a bold charcoal drawing effect. Everything runs in your browser — no uploads, no software.
Upload any image (PNG, JPG, WebP), choose your sketch intensity, and click Apply. Preview the result and download when satisfied. The tool also supports an edge-detection mode that emphasizes outline lines for a more technical illustration look.
The pencil sketch effect is popular for profile photos, avatars, social media art, blog post illustrations, and digital art projects. Artists use it as a starting point for digital drawing by converting a reference photo to a sketch layer they can trace or enhance.
Effect Modes
Pencil sketch. Grayscale sketch with soft pencil-like strokes. Best for portraits and natural subjects.
Edge detect. High-contrast outline drawing showing defined edges on a white background. Best for architectural and geometric subjects.
Colored pencil. Retains some color while applying the sketch overlay — a softer artistic effect that preserves subject colors.
Intensity control. Adjust from subtle (10%) to heavy (100%) pencil strokes. Combine with blur adjustment to control line softness.
