PDF vs PPTX for sharing a presentation
A PDF fixes each slide as a page that looks the same in any reader and cannot easily be changed, which makes it the safer file to send after a talk. A PPTX stays editable and keeps its animations and notes, but it depends on the recipient having suitable software and your fonts.
The file sent after a presentation is often read by more people than heard the talk. The format decides whether they see what you designed, whether they can change it, and whether they can find anything in it.

|---|---|---|
| Opens on | Any device with a PDF reader or a browser | PowerPoint or an app that imports it |
| Looks the same everywhere | Yes, the page is fixed | Depends on installed fonts and the app |
| Can be edited | Not in any practical sense | Yes, slide by slide |
| Animations and transitions | Lost, each slide shows its final state | Kept |
| Speaker notes | Only if exported as notes pages | Kept inside the file |
| Searchable text | Yes when made from text, no when made of images | Yes |
| Best for | Handouts, board packs, clients | Handing work to someone who will change it |
Two different promises
Every file you send makes a promise to the person who opens it. A PDF promises appearance: the slide they see is the slide you approved, on a phone, a tablet or a borrowed laptop, and nobody can quietly nudge a number before forwarding it. A PPTX promises continuity of work: the recipient can pick the deck up, change the wording, swap a chart and present it themselves next week. Both promises are useful, and they pull in opposite directions, because the property that makes a file easy to change is the same property that makes it look different on somebody else's machine. The decision is less about quality than about what the next person is meant to do with the file.
From printed handouts to the emailed PDF
A handout used to mean paper. PowerPoint still prints them, including a layout with three slide thumbnails down the left of each page and printed lines beside each one for note taking. Today the handout is usually a PDF emailed after the talk, and PowerPoint's own guidance puts the trade off plainly: saving as PDF lets anyone view the presentation even if they do not have PowerPoint, but they cannot make changes to it. The same export offers a standard quality setting for printing and a minimum size setting for email. Either way the PDF is a snapshot, so a deck that was revised after the meeting needs a fresh export rather than a forwarded copy of the old one.
Choosing by who opens it next
Send a PDF when the reader is outside your organisation, when the deck records a decision, or when it will be read on phones. Clients, boards, funders and conference delegates all fall into this group, and for them a file that cannot be altered and opens instantly matters more than editability. Send a PPTX when a colleague will present the deck, when an agency is handing work to an in house team, or when the recipient has explicitly asked to edit it. For readers who use a screen reader, check that the PDF actually contains text; if it is made of page images, a PPTX or a separate text document serves them far better than any handout. A mixed audience has a simple answer: send the PDF to everyone and the PPTX only to the person who asked to edit, so the version that circulates widely is the one that cannot drift.
Common mistakes
The most costly mistake is sending a PPTX with private notes still in it, since every note travels with the file to whoever it is forwarded to. The second is sending a PDF of a deck built with duplicated slides for reveals, so the reader pages through five nearly identical pages to reach each complete one. The third is attaching a file too large for the recipient's mail system because the photos were never compressed. The fourth is sending the file before the talk when the deck relies on reveals, which gives the ending away. The last is treating a PDF as tamper proof: it is harder to edit than a PPTX, not impossible, so a record that matters should be stored where the original is kept.
What the slide builder's PDF actually is
The PDF export is available on every plan and produces one landscape page per slide at the full 1920 by 1080 canvas, rendered on the server from the saved version. Each page is a screenshot captured at twice the canvas size, so it looks exactly like the deck in any reader, and its text is a picture: it cannot be selected, searched or read by a screen reader. The PowerPoint export is also a picture per slide, while the Editable PPTX export rebuilds text, lists, tables, images and charts as real objects; both PowerPoint exports are blocked on the Free plan. None of the three exports carries speaker notes. When a searchable PDF matters, one route is to export the editable PPTX, open it in PowerPoint and save that as a PDF, which keeps the text as text.
Questions people ask
How large can a deck be before email becomes a problem?
Many mail services cap attachments somewhere around 20 to 25 megabytes, and some company systems set the limit lower. A deck heavy with photographs passes that easily. Compressing images, exporting a PDF at a smaller size setting, or sending a link to the file instead of the file itself all avoid a bounced message the recipient never knows about.
Should a handout include every slide?
Not necessarily. Section dividers, a title slide repeated at the end and the intermediate stages of a reveal add pages without adding information. Many presenters send a slightly different version: the complete slides, one appendix slide with the detail they skipped for time, and the contact details. It reads better and answers the follow up questions before they arrive.
Can I stop someone editing a PPTX I send?
Not reliably. PowerPoint can mark a file as final or ask people to open it read only, but both are requests that a recipient can dismiss with one click. If the content must not change, send a PDF, or share the deck through a read only view where the recipient never holds an editable copy at all.
Why does my PDF have more pages than my deck has slides?
Usually one of three reasons. The export may have been set to notes pages or a handout layout rather than one slide per page. Hidden slides may have been included. Or the deck uses duplicated slides to reveal content in stages, and each stage becomes its own page. Check the export settings first, then the slide list.
Should the file go out before or after the talk?
After, in most cases, because a deck read in advance takes the surprise out of the argument and invites people to skim instead of listening. The exception is a meeting where the deck is the pre reading, such as a board pack, where members are expected to arrive having read it and the discussion replaces the presentation.
Is a PDF or a PPTX better for printing?
A PDF, because the page size and fonts are fixed and the print shop or office printer reproduces exactly what you checked on screen. A PPTX sent to print is redrawn by whatever software opens it, which is where substituted fonts and shifted text boxes appear. Check that the slides are legible at the printed size before sending.
