Part 4 of 7 · PPT & PDF
PPT — slide viewer
Presentations open as a viewer: you can read and print slides and export them to PDF, but the file is never rewritten.
Read-only by design. The PPT page has no editing commands, no add-slide button and no save action. Use PowerPoint or another editor to change the deck, then reopen it here.
Reading a deck
- The left panel lists every slide; click a thumbnail to jump to it.
- The current slide fills the preview area, scaled to fit.
- The ‹ and › buttons above the preview step one slide at a time; the counter between them shows position and total.
- Keyboard navigation works anywhere on the page — see Keyboard & mouse.
Exporting
Export PDF turns the whole deck into a multi-page PDF and is enabled once a presentation is loaded. The status bar marks the page as read-only so it is always clear whether a change can be saved.
Binary .ppt files (PowerPoint 97–2003) cannot be opened. Only the modern XML formats are supported. Save the file as .pptx in another app first.
PDF — reading & annotating
The PDF page is a viewer with the usual reading tools in its own toolbar, plus a status bar that reports page, size and zoom.
Reading tools
- Navigation — page thumbnails, previous/next and page jumping live in the viewer toolbar.
- Zoom — opens fitted to width by default; the toolbar switches to page fit or a percentage.
- Search — find text in the document and step through the hits.
- Selection — select and copy text, or take a snapshot of a region.
- Layers — PDFs with optional content groups can show and hide layers.
- Annotations — highlight, underline, strike out, and add notes with the annotation tools.
What each button does
| Button | Behavior |
|---|---|
| Open | Choose a PDF to read. |
| Opens the print dialog; it stays disabled until a document is loaded. | |
| Save As… | Saves a copy named name-copy.pdf by default, including any annotations or form changes you made. The original file is left untouched. |
| Help | Opens this guide. |
Annotating never edits the original. Because Save As… always writes a new file, you can mark up a document you do not own without any risk of altering it.
The status bar shows the current page and total, the file size, and the zoom mode (“Fit width” or a percentage).
