Use PixelOkay Halftone Image Generator to transform photographs into newspaper-style dot screens, comic book illustrations, stippled monochrome portraits, crosshatch etchings, or CMYK-inspired graphic art. Adjust dot spacing, rotation, tonal range, paper tint and ink colors, preview changes, and export to PNG, vector SVG, or printable PDF — all in your browser.
How does a halftone effect work?
Halftone screens represent darker image regions with larger or denser printed marks. This editor samples the source image, calculates tonal coverage and draws a deterministic grid of individual dots, squares, diamonds or strokes. You can also create colored dots and simulated multi-ink screens. For precise commercial printing, use professional color-managed separation software.
Private and portable
Imported images are processed locally and are not uploaded by this tool. Download editable projects to return to your work later, and back up important designs outside browser storage.
Using Halftone Image Generator
Turn a local photo into a halftone treatment by choosing a pattern, tuning tone and color, and reviewing the result before export.
Workflow
Open a PNG, JPEG or WebP up to 20 MB or the portrait sample
choose a dot, line, stipple or comic pattern and tune color
compare and export PNG, SVG, PDF or project JSON.
Example
Use the portrait sample with a comic pattern and duotone colors, then save a PNG and project JSON to reopen the settings.
Limits and data handling
Simulated CMYK is a visual treatment, not calibrated separations, spot screening or prepress proofing. Preview/export resolution and memory use differ. Browser recovery is best-effort; retain a JSON project backup. Check SVG/PDF and print color in downstream software.
FAQs
Is simulated CMYK ready for commercial printing?
No. It is a visual effect, not calibrated separations or prepress-certified output.
Can a project contain my source image?
Project data can retain source image content; inspect it before sharing and keep sensitive backups private.
