From preparation
to the next slide.

How do I prepare the running order?

The running list keeps the order you set. Importing, loading or selecting a PDF does not sort it. Files with the same name remain separate entries, and reaching the last slide does not automatically start the next PDF.

1. Add your PDFs. The PDFs tab stays available so you can arrange them.
2. Use the reorder controls to put the presentations in event order.
3. Select a presentation to prepare it and check its pages.
4. Lock the running order when preparation is complete.
5. Save the event to keep a portable copy of the PDFs and event data.

Can I replace a PDF without changing its place?

Yes. Replace a PDF in its existing slot to keep its place in the running order. Presentations can also have an optional title and speaker, helping you identify each item at the control desk.

What does Check event verify?

Check event verifies the documents, pages and local resources needed for offline operation. Use it during preparation, then check the audience display and your controls in the actual AV setup. It does not certify a monitor or clicker.

How do I put the slides on the audience screen?

Show opens a normal audience window on the app's screen. Your private Presenter View remains separate. The audience window contains only the current slide, without controls or branding.

1. Select a prepared PDF and choose Show.
2. Move the audience window to the audience display.
3. Use the browser's fullscreen command. On Windows, the intended workflow uses F11.

How does the page fit the screen?

The whole PDF page fits proportionally within the useful window area, whether the window is normal size or fullscreen. Margins depend on the shape of the page and display.

The macOS browser fullscreen workflow has not yet been verified. Platform and browser requirements will accompany the approved release.

Can a speaker have a support monitor?

Your AV setup can send the same Presenter View shown at the control desk to a speaker support monitor. LimePDF does not provide a separate third speaker-view mode.

What is the difference between Split and Focus?

Split shows Current and Next previews, a horizontal filmstrip and compact navigation. The current thumbnail centres as you navigate.

Focus gives the Current preview more space, with a lime outline, a vertical filmstrip on the right, and navigation and elapsed time below. As you navigate, the current thumbnail sits in the second visible position.

Switching dashboards preserves the presentation and elapsed time. Your dashboard choice and area sizes are remembered locally.

Can I look ahead without changing the public slide?

Yes. Scroll through the filmstrip to explore thumbnails without changing the audience output. Selecting a thumbnail changes the slide. Navigation or selection returns the filmstrip to its current-slide anchor.

How do I adjust the preview and filmstrip areas?

Drag a divider to resize its areas; the previews redraw as you adjust them. With a divider focused, use + or - to adjust its size, or Home to reset it. You can also hide the filmstrip.

When do keyboard shortcuts and clickers work?

One LimePDF window must have focus. Compatible clickers send the supported keyboard keys listed below. Commands do not control LimePDF while another app has focus, and editable text fields keep their normal editing behaviour.

To jump directly, type the page number, counted from 1, then press Enter. Use Backspace to correct the number before confirming.

How do the clock and elapsed timer work?

The local clock and elapsed time are visible by default and can be disabled. Elapsed time starts when Show is confirmed visible, pauses on Stop or interruption, and resumes for the same presentation. Press T to reset it while preserving its running or paused state.

What does a .limepdf event contain?

Save event creates a portable .limepdf package containing the actual PDFs, their exact order and associated event data. Use it to back up your preparation or transfer it to another computer.

Event and PDF content stays in memory unless you explicitly save it. Reloading the app requires reopening your event or PDFs.

Where is my saved event?

Where supported, Save event opens a native Save As picker. Otherwise, it starts a browser download. Check the browser's downloads to find the package: a download-started message does not confirm its final disk location or that the write has finished.

What happens when I open an event?

Open event validates the package and shows a summary. You must confirm before it replaces the current event. Opening does not start Show, restore public output or resume elapsed history.

How do I make the audience output black?

Choose Stop to black the audience output while retaining the current slide position. Escape also stops output when the command reaches LimePDF. The browser or operating system may use Escape to leave fullscreen first.

What should I do if the audience window is lost or reloaded?

LimePDF requires explicit recovery before projecting again when the output window is lost or reloaded, or a real interruption is detected. Follow the app's recovery controls and check the audience display before continuing.

If the browser blocks the output popup, allow the app's output window and choose Show again.

Are my PDFs uploaded?

PDFs are processed locally, without uploading them or requiring an account. LimePDF does not execute scripts embedded in PDFs. Save an event explicitly when you want to keep or transfer its content.

Can I use LimePDF offline?

For offline use, the app's initial preparation and cache loading must finish while connected. Use Check event to verify local resources, then test reopening the app and your saved event without a connection in the installed window you will use at the event. An app icon alone does not make LimePDF ready offline.

Offline preparation does not save your event permanently. Keep a saved .limepdf package so you can reopen your PDFs after a reload.

Chrome on Windows

When the Beta is available, open the app through Open Beta. Install from the app page, rather than this informational website. Chrome can give it its own window and desktop shortcut.

1. In Chrome, use the address-bar Install icon when offered, or open More > Cast, save, and share > Install page as app. Confirm the installation.
2. Open the installed app from its shortcut. To create another shortcut, enter chrome://apps in Chrome, right-click the app and choose Create shortcut.

Edge on Windows

Edge can install a website as an app and open it in a separate window. When public access is available, start from the LimePDF app page.

1. Use the installation option offered by Edge, or open Settings and more > More tools > Apps > Install this site as an app.
2. For launch shortcuts, enter edge://apps, choose Details for the installed app, then use Pin to taskbar, Pin to Start or Create Desktop shortcut.

Safari on Mac

Safari offers Add to Dock on macOS Sonoma 14 or later. Use this browser command; there is no need to wait for an Install button inside the app.

1. When the Beta is available, open its app page in Safari, then choose File > Add to Dock.
2. Confirm the name and choose Add. The web app is saved in the Applications folder inside your home folder and can be opened from the Dock or Spotlight.

Chrome on Mac

Chrome on macOS can install web apps that open in their own window. This is separate from Safari Add to Dock.

1. When the Beta is available, open its app page in Chrome. Use the address-bar Install icon when offered, or More > Cast, save, and share > Install page as app.
2. Confirm the installation, then launch the installed app. Chrome also lists installed apps at chrome://apps.

Firefox on Windows

Firefox offers web apps on Windows in versions with the feature available. Its simplified app window remains tied to the Firefox profile. Mozilla does not currently document this feature as available on macOS.

1. When the Beta is available, open its app page. If your Firefox version offers Add tab to taskbar in the address bar, select it and follow the pinning prompt.
2. Use that taskbar entry to reopen the web app. If the option is absent, check the Firefox version and the verified LimePDF release requirements.

Can I use the LimePDF Beta now?

LimePDF is in development. Its first public release will be a free Beta, accessed from this website and installed through the browser. Public access is not available yet; supported platforms and browsers will be listed with the approved release.

The Beta will not require an account, email registration, payment or licence activation.

How will I install LimePDF?

When the Beta is ready, Open Beta will take you to the app. Follow the verified release requirements and the short installation guide. Installation uses browser controls, which differ between Chrome, Edge, Safari and Firefox; an Install button inside the app is not required in every browser.

Complete preparation and cache loading while connected, then test offline reopening and your saved event in the installed app. Browser storage can be cleared; installation does not replace saving your event as a .limepdf file.

How should I report a problem with the Beta?

When the Beta is available, report problems to [email protected]. If possible, include the app version, your operating system and browser, and the steps that led to the problem. You do not need to send private PDFs.
