I'm excited to share Image to Pencil Sketch Art Tool . a tool I built because turning photos into art shouldn't require expensive software or privacy sacrifices. The problem: Every time I wanted to turn a photo into a pencil sketch — for art projects, gifts, or just for fun. I had to use heavy desktop software like Photoshop or upload my images to sketchy online tools. The desktop tools were expensive and complicated. The online tools uploaded my photos to servers I didn't trust. The solution: A photo-to-sketch converter that runs 100% in your browser — with real-time artistic control: ✏️ Real-Time Pencil Sketch Generation — Watch your photo transform into a hand-drawn sketch instantly. Adjust the "Sketch Strength" slider and see the effect update in real-time — no waiting, no rendering delays. 🎨 Adjustable Sketch Strength — Fine-tune the artistic effect with a simple slider. Higher values create thicker, darker lines for a dramatic pencil look. Lower values preserve more detail for a subtle, delicate sketch. 🔄 Side-by-Side Comparison — Drag the comparison handle to see the original photo alongside your sketch. Perfect for showing off the transformation. 📸 Multiple Format Support — Upload JPG, PNG, or WebP images. Download your sketch as JPEG or PNG. ⚡ Advanced Canvas Rendering — Built using pure vanilla Canvas API with zero heavy libraries. The sketch is created through a sophisticated image processing pipeline: grayscale conversion → inversion → box blur → color-dodge blend — producing authentic hand-drawn sketch lines. 🖼️ 2000px Support — Process images up to 2000px dimension for high-quality results. 🛡️ 100% Private — Your photos never leave your device. No uploads. No servers. No tracking. Your personal photos, family portraits, and creative projects stay yours. 🆓 100% free — No watermarks. No sign-up. No limits. Convert as many images as you want. Who is this for? - Artists creating reference sketches - Designers adding artistic effects to projects - Anyone turning personal photos into unique gifts - Creative professionals who value speed and privacy The key insight: Most online sketch generators upload your photos to servers. We don't. We literally can't access your images because they never leave your browser. That's the difference between a privacy policy and privacy by architecture. I'd love your feedback! Try it out and let me know what you think.

the side-by-side comparison slider is honestly such a nice touch, makes it really easy to dial in the sketch strength without losing the original. runs entirely in the browser too which is kind of amazing for something this smooth.
