Photo to Dots — Halftone & Pattern Generator

Turn any photo into halftone dot art

Photo to Dots is a free, browser-based halftone generator that converts your images into clean, scalable dot art. Drop in a photo and it's rendered as a halftone, ASCII, pixelated, or cross-hatch pattern in seconds — then export it as an infinitely scalable SVG or a high-resolution PNG. It's the quick way to give a photo a printed, comic-book, or risograph feel without opening heavy design software.

Everything runs locally in your browser, so your pictures are never uploaded to a server — no account, no watermark, no waiting.

How to make a halftone image

1. Upload a photo — drag & drop or choose a JPG, PNG, or WEBP. You can add up to five images at once.
2. Pick a pattern and style — switch between halftone, ASCII, pixelate, and hatch, then fine-tune dot size, contrast, detail, frame, and colors.
3. Download — export a crisp vector SVG or a high-res PNG, one image at a time or all of them together.

Four halftone & pattern styles

• Halftone — the classic printing screen, where dot size grows with darkness for a smooth tonal range.
• ASCII — the photo redrawn in monospace characters, from sparse dots in the highlights to dense glyphs in the shadows.
• Pixelate — a mosaic of solid blocks whose opacity tracks the shadows.
• Cross-hatch — parallel lines that thicken in darker areas, like an engraving or pen sketch.
