A free, do-it-yourself photo booth for your wedding, party, or event. Run it on any Windows laptop or mini-PC with a webcam, hit START, and your guests get a classic 2×6 photo strip — the same kind you'd pay a rental company hundreds of dollars for.
- A big, friendly full-screen booth with a live preview so people can see themselves.
- A "3 · 2 · 1 · Smile!" countdown before each of four photos.
- A printed 2×6 photo strip — and with a photo printer that cuts, two copies so everyone gets one.
- Every photo and strip is also saved to your computer (in
Pictures\MonoBooth) as a keepsake.
- Download the latest
MonoBooth-Setup.exefrom the Releases page. - Run the installer. It adds MonoBooth to your Start menu (and the desktop, if you like). Nothing else to install.
- Plug in your webcam — and your photo printer, if you have one.
- Turn on camera access: open Windows Settings → Privacy & security → Camera, and switch "Let desktop apps access your camera" to On. (If this is off, MonoBooth says "No camera found.")
- Open MonoBooth, press START, and smile! Press Esc when you're done to close the booth.
💡 Tip: Set the booth PC to never sleep, and put MonoBooth's shortcut in your Startup folder so it launches on its own — then the laptop is ready the moment you open it.
MonoBooth prints a 2×6 strip and asks the printer for 2 copies by default — perfect for a dye-sub photo printer like the Kodak 6850 loaded with 2×6 media, which prints and cuts each strip automatically. No photo printer? No problem — MonoBooth simply skips printing and still saves every photo to your computer.
You can change how many copies print (or turn printing off) in Settings below.
Add your own background art — the couple's names, an event logo, a fun frame — and the booth becomes your booth:
- Save your picture somewhere (a full-screen image works best).
- Point
BackgroundImagePathat it in the settings file (see below). - Open MonoBooth and right-click-drag the live preview or the photo strip to sit them nicely on your artwork. Your arrangement is saved automatically when you exit.
The booth ships with the pink design shown above, ready to use out of the box.
MonoBooth keeps its options in a small text file you can edit:
%LOCALAPPDATA%\MonoBooth\settings.json
(Paste that path into the File Explorer address bar to find it.) Change a value, save the file, and reopen MonoBooth.

- A Windows 10 or 11 computer (most laptops from the last several years work great).
- A webcam — built-in or USB.
- Optional: a photo printer (a 2×6-capable dye-sub like the Kodak 6850 gives the real photo-booth experience).
