Convert PowerPoint to PDF

Why share slides as a PDF instead of a PPTX?

A PDF keeps every slide exactly where it was placed, on any device, without presentation software. A PPTX file depends on the viewer's software: Keynote, Google Slides and older PowerPoint versions each move text boxes and swap fonts in their own way, and a 60 MB deck with embedded media is awkward to email.

PDF slides are also easier to review. Recipients can annotate them in any PDF reader, search the text of the whole deck, and read it on a phone. Keep the original PPTX for presenting, since animations and speaker notes live there, and send the PDF to everyone who only needs to read or print the slides.

What changes when a PowerPoint becomes a PDF?

Everything that moves is dropped, and everything static is kept. Slides are rendered as they look at the end of their build, one slide per PDF page, at the deck's own aspect ratio (16:9 or 4:3). Text stays selectable and searchable, and charts are drawn as vector graphics where possible, so they stay sharp when zoomed or projected.

• Animations, transitions and slide timings are dropped.
• Video and audio are not embedded; the poster frame may appear.
• Hidden slides are skipped; delete other unwanted slides before converting, or remove them from the PDF later.
• Slide numbers and footers appear only if they are switched on in the deck.
• Hyperlinks usually remain clickable.

How does the PowerPoint to PDF conversion run?

The deck is uploaded over HTTPS and exported to PDF by LibreOffice Impress in an isolated container with no internet access. Rendering a presentation accurately needs a full office suite, which a browser tab can't provide, so this tool is one of three on the site that use a server.

The file is converted once, in its own temporary folder, and deleted along with the output right afterwards. Macros never run, linked media is never fetched, and the log records only the extension, size, status and duration of the request. Conversions are capped at 90 seconds, which a deck under 25 MB rarely approaches.

Which fonts render faithfully?

Calibri, Cambria, Arial, Times New Roman and Courier New render with metric-compatible replacements, so text boxes keep their line breaks. Those replacements are Carlito, Caladea and the Liberation family. Noto fonts cover Greek, Cyrillic and most other scripts, although the letter shapes differ from the fonts Microsoft ships.

Chinese, Japanese and Korean fonts are not installed, and brand or display typefaces are replaced with the closest match, which can make a title wrap onto a second line. For decks that rely on such fonts, PowerPoint's own File › Export › PDF gives an exact result, or the affected titles can be switched to a common font first.

What are the advantages over other online converters?

No account, no watermark, no stored files and no slide limit beyond the 25 MB cap. The PDF streams directly back to the browser instead of sitting on a download page, so there is no link that someone else could open later, and nothing is retained for analytics or training.

For decks under NDA, exporting locally is still the most private choice. PowerPoint's File › Export › PDF, or Keynote's Export To › PDF on a Mac, keeps everything on the computer. Every follow-up task on this site, such as splitting, watermarking or compressing the PDF, runs in the browser without an upload.

How do you make good handouts from slides?

Use a light theme, trim the deck and check the page count. Dark slide backgrounds use a lot of ink, so a light theme suits decks that will be printed. To send only part of a talk, convert the whole deck and keep the slides needed with Split PDF or Remove Pages. To mark a deck as draft or confidential, stamp every page with Add Watermark.
