Free Star Map Generator
Recreate the exact night sky from any place, date, and time, free. Real stars and constellations, elegant captions, and circle, heart, or full-sky 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 sky is calculated exactly as it looked from that spot.
Set the date, and optionally a precise time. The real stars and constellations move to match your chosen moment.
Choose a shape (full, circle, or heart), a colour palette or your own sky and star colours, and toggle the constellation lines and coordinate grid.
Add captions: the place name, coordinates, the date, 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. Turn off the glow and use the black-on-white palette for the crispest engrave.
Pro Tip: Leave the time unset for a classic evening sky (around 9 pm local). For laser engraving, pick the black-on-white "Engrave" palette, turn off the glow, and export the SVG so stars become filled circles and constellations become strokes.
About
This free star map generator recreates the real night sky as it appeared from any location on Earth, on any date and time. It uses a genuine catalogue of over five thousand naked-eye stars and the classic constellation figures, projected exactly as you would have seen them looking straight up. Add the place name, its coordinates, the date, and a personal dedication to turn a moment, a wedding, a birth, or an anniversary, into a keepsake.
Choose a full-sky rectangle, a circular star chart, or a heart, pick from elegant colour palettes, and fine-tune the star density and captions. Design it as art or switch to laser mode, where stars, constellations, the frame, and 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 star map 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 uses a real catalogue of over five thousand naked-eye stars (down to magnitude 6) and the classic Western constellation figures. For your chosen place, date, and time it computes each star's real position in the sky using local sidereal time, so the map matches what was actually overhead.
Star positions are accurate to well within the width of a printed dot. Time is handled using the location's longitude, which is exact to within a time-zone offset, more than precise enough for a poster. If you leave the time unset, an evening sky (around 9 pm local) is used.
A high-resolution PNG (up to 4096px, roughly 300 dpi at A4) for printing and framing, and a clean single-layer SVG that scales to any size. The SVG drops straight into laser and CNC software for engraving on wood, acrylic, or slate.
Yes. Turn off the glow, pick the black-on-white 'Engrave' palette (or any two colours), and export the SVG. Stars become filled circles and constellations become strokes, ready to engrave or cut. A transparent background option is included for layering.
Full-sky rectangle, a circular star chart, or a heart. Choose from palettes like Night Gold, Blueprint, and Noir or set your own sky and star colours, toggle constellation lines and the coordinate grid, add a bold frame, and add a place name, coordinates, date, and a personal dedication in your choice of fonts.
