Auto-Advance Timer
Set your PDF to move forward automatically. Any duration — seconds, minutes, or milliseconds via --auto.
Boozle turns any PDF into a fullscreen, timed presentation. Use it for trade show booths, kiosks, lobby screens, Ignite talks, classrooms, and hands-free slide playback. No presentation suite. No browser workaround. No runtime to install.
Open source · Apache-2.0 · Built in Go · macOS · Linux · Windows
Sometimes you already have the slides exported as a PDF. You just need them to open fullscreen, advance on a timer, loop cleanly, and look sharp on the screen you choose.
Manual clicking gets old. Auto-advance your PDF every few seconds, minutes, or milliseconds — with a configurable interval per slide.
Generic PDF viewers are not presentation tools. Loop mode, progress overlays, page ranges, monitor selection, and slide overview are built for presenting — not reading.
Big presentation suites are overkill. Boozle is focused on one job — reliable fullscreen PDF playback. Download, run, present.
Everything a kiosk needs. Nothing it doesn't.
Set your PDF to move forward automatically. Any duration — seconds, minutes, or milliseconds via --auto.
Perfect for booths, signage, kiosks, and lobby screens. Add --loop and the deck runs forever without a hiccup.
Override timing per slide using a TOML sidecar file that lives next to the PDF. Important slides get more time; quick slides get less.
A segmented rainbow bar shows page position, current page, and auto-advance countdown. Enable it with --progress.
Press Tab to reveal a thumbnail grid of all slides and jump to any page. With presenter view on, the grid opens on your screen only, so the audience never sees it.
Re-rasterises pages at native pixel density on Retina and 4K displays. Your PDFs look exactly as designed.
Native binaries for macOS (Intel & Apple Silicon), Linux (x86_64 & ARM64), and Windows. One tool for every screen.
Choose the audience display with --monitor, or add a separate speaker display with --presenter-monitor, by index or by name like HDMI-1.
Open a speaker window with current slide, next preview, per-slide notes, clock, elapsed time, slide counter, and timer via --presenter-monitor. Notes come from TOML, .pdfpc, or PowerPoint.
Run boozle notes import deck.pptx once to extract speaker notes into a TOML sidecar. After that, present with only the PDF — the .pptx isn't needed.
Run boozle --list-monitors (or -M) to print the index, name, size, and scale of every connected display, then pass the index or name to --monitor.
Use the default lateral push, cross-fade between pages, or cut instantly with --transition.
Download, run, present. No installer, no runtime, no package manager. Copy the binary and it just works.
Already use PDF Presenter Console? Boozle reads .pdfpc files directly: page order, hidden slides, and speaker notes carry over as-is.
Near-instant startup, renders off the UI thread, and memory bounded by a small GPU cache, not by deck length. Big decks stay smooth.

boozle --versionWherever a PDF needs to run itself, Boozle fits.
Run your booth presentation all day from a PDF. Export the deck, start Boozle in fullscreen, and let it loop for the entire event.
boozle booth.pdf --auto 15s --loop --progressTurn any display into a PDF signage screen — welcome messages, event schedules, announcements, or donor lists.
boozle lobby.pdf --auto 30s --loopMuseums, galleries, product displays, and information desks — a focused PDF viewer for kiosk-style playback on any screen.
boozle kiosk.pdf --auto 20s --loop --pages 1-12Teach or demo hands-free. Use auto-advance for pacing, pause when discussion starts, and pick up on the second monitor.
boozle lesson.pdf --auto 45s --monitor 1 --progress20 slides, 15 seconds each, fully automated. Export your Ignite deck as a PDF and let Boozle handle the timing — no clicker needed.
boozle ignite.pdf --auto 15s --autoquitA single command is all it takes.

| Need | Boozle | PowerPoint / Keynote | Generic PDF Viewer |
|---|---|---|---|
| Auto-advance a PDF | ✓ Built-in | Requires import / export | Rarely supported |
| Loop fullscreen | ✓ --loop flag |
Possible but heavy | Often awkward |
| Per-slide timing | ✓ TOML sidecar | Native slide files only | Rare |
| Single command launch | ✓ One binary | No | Sometimes |
| Monitor selection | ✓ --monitor <N|name> |
Presenter mode only | No |
| Designed for kiosk loops | ✓ Primary use case | Partly | No |
| Zero dependencies | ✓ Static binary | Full install required | Often requires runtime |
--auto with any duration (e.g. --auto 30s or --auto 2m) and Boozle will advance slides automatically at that interval.
--loop and Boozle restarts from slide 1 after the last page. It runs indefinitely — ideal for kiosk displays and booth screens.
.toml sidecar file next to your PDF with [[page]] entries specifying an n (page number) and auto override. The global default applies to all other pages.
--monitor 1 (any display index) or --monitor HDMI-1 (a display name, or any unique part of it) to open the presentation on a specific connected display. Display 0 is the primary screen.
--auto 15s on a 20-slide PDF and it advances automatically every 15 seconds, running the full 5 minutes hands-free. Add --autoquit so it exits cleanly when the last slide is done.
boozle notes import deck.pptx once to extract speaker notes into a deck.boozle.toml sidecar. From then on you only need the PDF plus the sidecar at presentation time — the .pptx file isn't needed. Old binary .ppt files should be converted to .pptx first.
boozle --list-monitors (or -M) to print the index, name, size, and scale of every connected display. Then pass the index or name you want to --monitor or --presenter-monitor. Names stay stable across reboots on macOS and Linux.
deck.pdfpc next to deck.pdf automatically, or any .pdfpc file passed with --config. It uses the page order, skips hidden slides, and shows the notes in presenter view. See pdfpc Sidecars.
