Free Moon Phase Generator
Recreate the exact phase of the Moon from any place, date, and time, free. Real lunar phase math, elegant captions, and circle, heart, or full shapes. Download a print-ready PNG or a laser-ready SVG.
How To Use
Pick a place: choose a city from the quick list, type any latitude and longitude, or enter your own place name. The phase is calculated for that spot's local time.
Set the date, and optionally a precise time. The Moon's illuminated shape moves to match your chosen moment, from a thin crescent to a full moon.
Choose a shape (full, circle, or heart), a colour palette or your own sky and moon colours, and toggle the realistic NASA surface texture and the horizon orientation.
Add captions: the place name, coordinates, the date, the phase name, and a personal dedication, each in your choice of font.
Download a high-resolution PNG for printing and framing, or a clean SVG for laser engraving and CNC. Use the black-on-white palette for the crispest engrave.
Pro Tip: Turn on the realistic surface for a real, engraved Moon. For laser engraving, pick the black-on-white "Engrave" palette and export the SVG so the lit area becomes a filled engrave, the disk and terminator become score lines, and the frame cuts.
About
This free moon phase generator recreates the exact phase of the Moon as it appeared from any location on Earth, on any date and time. It uses standard lunar phase astronomy to compute the illuminated fraction and orientation, then draws the crescent, quarter, gibbous, or full disk with a smooth terminator. Add the place name, its coordinates, the date, the phase name, and a personal dedication to turn a moment, a wedding, a birth, or an anniversary, into a keepsake.
Choose a full-frame moon, a circular vignette, or a heart, pick from elegant colour palettes, and toggle the realistic surface, a genuine map of the Moon's near side built from NASA Lunar Reconnaissance Orbiter imagery, so the real maria and highlands appear in the right places. Design it as art or switch to laser mode, where the illuminated moon, the disk and terminator, the frame, and the text each export as their own coloured group so LightBurn and xTool can assign engrave, score, and cut operations. Download a high-resolution PNG, a layered SVG for laser cutting and CNC, or open it straight in the Design Editor.

Frequently Asked Questions
Yes. Design and download your custom moon poster for free, with no watermark and no sign-up. Everything runs in your browser, so your dates and locations never leave your device.
Yes. The tool computes the Moon's real illuminated fraction and phase for your chosen date and time using standard astronomical formulas, then draws the terminator (the line between light and shadow) exactly, from a thin crescent through to a full moon. It also labels the phase name and illumination percentage.
A keepsake of the moon on a wedding day, a birth, an anniversary, or the night you met. Add the place name, coordinates, the date, and a personal dedication, and choose a full, circular, or heart shape.
A high-resolution PNG for printing and framing, a clean print SVG, and a layered SVG for laser cutting and CNC where the lit area, the terminator, the frame, and text each export as their own coloured group for LightBurn and xTool.
Yes. Pick the black-on-white 'Engrave' palette, turn off the glow, and export the SVG. The illuminated area engraves and the disk outline scores or cuts, ready for wood, acrylic, or slate.
