MakeHalftone

MakeHalftone is a free browser-based halftone generator that converts any photo or image into a print-ready dot pattern — instantly, with no uploads, no account, and no watermarks.

A halftone is the technique used in screen printing, newspaper photos, comic books, and poster art to simulate gradients using solid ink dots. Instead of printing continuous tones (which most presses cannot do), halftones use a grid of dots that grow larger in dark areas and shrink in light ones — tricking the eye into seeing shades when viewed at a distance.

MakeHalftone brings this classic print technique to your browser in seconds. Drop in a photo, adjust the dot size, spacing, angle, and contrast using live sliders, and export a print-ready PNG at 300 DPI or a scalable vector SVG — all for free.

Everything runs locally in your browser using the Canvas API. Your image never leaves your device, never touches a server, and the tool works offline once the page has loaded.

Key Features

• Live preview with drag-to-compare — every slider updates the canvas instantly with a side-by-side comparison against your original image — no Generate button, no waiting
• Four classic halftone screens — Dot, Line, Ring, and Diamond patterns, each rotatable to any angle from 0° to 180°
• Free SVG and 300 DPI PNG export — true vector SVG that stays sharp at any print size, plus 300 DPI print PNG — both free, no watermark, no account
• Transparent background export — tick one checkbox and the paper colour is removed, leaving only the ink — ideal for DTF transfers and layered print work
• CMY colour simulation — toggle a print-style colour halftone that approximates cyan, magenta, and yellow separations at classic screen angles
• 100% private by design — processing happens entirely in your browser with the Canvas API — no upload endpoint exists, verified in the browser’s network tab
• Adjustable controls — dot size, spacing, screen angle, threshold, and contrast all adjustable with live feedback
• Works on desktop and mobile — fully functional in modern browsers on any device
• No account, no subscription, no watermark — completely free with no hidden costs

How It Works — 3 Steps

Step 1 — Add your image Click to upload, drag and drop a file, paste from your clipboard, or start from one of the built-in sample images. The image opens instantly — nothing is uploaded to any server.

Step 2 — Dial in the halftone Choose your pattern type (Dot, Line, Ring, or Diamond), then adjust size, spacing, angle, threshold, and contrast using live sliders. The preview updates in real time with a drag-to-compare view against your original.

Step 3 — Export for print or web Download a free PNG at web or 300 DPI print resolution, or a vector SVG that scales to any size. Optional transparent background available on all pattern types.

Use Cases

Screen Printing Upload your artwork, select Dot pattern, adjust spacing to match your mesh count, and export a 300 DPI PNG or SVG ready to send to your screen burner. The threshold and contrast sliders let you clean up highlights and shadows before export.

DTF Transfers Use the transparent background PNG export to isolate the halftone ink layer from the paper colour. Works on all four pattern types — ideal for layered DTF artwork where background removal is essential.

Poster and Apparel Design Apply the classic halftone dot or ring pattern to a photo for retro poster aesthetics. Export SVG for scalable artwork that stays sharp at any print size — from A4 to A0.

Laser Engraving and CNC Convert photos to line or dot halftone patterns for material engraving. The angle control lets you match the pattern direction to your engraving path for cleaner results.

Risograph Printing Use CMY colour simulation to approximate how a photo will separate across risograph colour layers. Export individual channel PNGs for each colour pass.

Frequently Asked Questions

Is MakeHalftone completely free?

Yes. Every feature — all four pattern types, SVG export, 300 DPI PNG, transparent background, CMY colour simulation — is free with no account, no subscription, and no watermark on any export.

Are my images uploaded to a server?

No. Everything is processed locally in your browser using the Canvas API. Your image never leaves your device, there is no upload endpoint, and the tool works offline once the page has loaded. You can verify this yourself in your browser’s network tab — no image requests are made.

What file formats can I export?

MakeHalftone exports two formats: SVG (true vector, scales to any size without quality loss) and PNG (web resolution or 300 DPI print resolution). Transparent background is available on PNG exports across all four pattern types.

What pattern types are available?

Four classic halftone screens: Dot (the standard circle screen used in commercial print), Line (great for engraving and etching), Ring (bold stylistic look popular for posters and apparel), and Diamond. Each can be rotated to any angle from 0° to 180°.

Is MakeHalftone suitable for professional screen printing?

Yes, with one caveat — the tool produces artistic halftone patterns tuned for screen printing, DTF, and poster work. For professional colour separations or precise LPI matching, confirm the exported artwork with your print shop before burning screens. The tool displays the grid density (LPI) at your chosen print size to help with this.

Does it work on mobile?

Yes. MakeHalftone is fully functional on phones and tablets in modern browsers. The interface adapts to smaller screens and all export options are available on mobile.

Is batch processing available?

Not yet. Images must be processed one at a time. Batch processing is listed as a coming feature on the platform.
