Tips

Tips for a complete text PDF of your slides

This tool is all about the words on your slides, so these checks make sure every one of them comes through.

  • Refer to slides by their headingEach slide starts a new page with room for about 25 lines of text, and anything more carries on to a page headed, for example, Slide 4 (continued). PDF page numbers can then run ahead of slide numbers, so when you ask for comments, point people to the Slide headings rather than page numbers.
  • Swap symbols and emoji for wordsThe PDF’s built-in font can’t draw everything: common symbols such as → and ✓ become -> and v, while emoji and letters outside Western European alphabets show as “?”. The conversion still finishes, but if a slide relies on a symbol for meaning, such as a ✓ in a comparison, swap it for a word such as “yes” first.
  • Give every slide a titleEach page is headed Slide 1, Slide 2 and so on, and the slide’s own title appears as one of its bullets, usually the first. A slide without a title starts straight into its points, so adding a short title to each one makes the PDF much easier to scan.
  • Remove hidden slides you don’t wantHidden slides are included and numbered in with the rest. If some are backups or out-of-date versions, delete them from a copy of the presentation before converting, so the PDF matches what you actually present.

Like every Altto tool, this runs on your device — nothing you add is uploaded. How Altto works

1 page

per slide, headed Slide 1, Slide 2 and so on, with a very wordy slide running on to an extra page marked (continued), so anyone commenting on the PDF can point to a slide by its number.

FAQ

Frequently asked questions

What PowerPoint to PDF picks up from a presentation, and what it can’t. Need to go the other way? See PDF to PowerPoint.

Will this look exactly like my slides?
No — this pulls out the text content of each slide (titles and bullet points) and lays it out as a simple document. Images, backgrounds, fonts and exact positioning aren’t reproduced, since there’s no way to render a real slide design in a browser tab without a much heavier engine.
Does this work with the older .ppt format?
Not yet — only the modern .pptx format (PowerPoint 2007 and later) is supported. Save your file as .pptx from PowerPoint first if needed.
What if I need an exact visual copy of my deck?
Use PowerPoint's own "Export → Create PDF" or "Save As PDF" feature for a pixel-accurate export — this tool trades that for the ability to run entirely in your browser with no upload.
Can I convert a password-protected presentation?
No, encrypted PowerPoint files can't be read in the browser. Remove the password in PowerPoint first, then convert it here.
Are speaker notes included?
No. Only the text on the slides themselves is read, so anything in the notes pane under each slide is left out. If you need your notes in a PDF, print the presentation from PowerPoint using the Notes Pages layout and choose a PDF printer, or copy the notes onto a spare copy of the slides first.
What happens to tables and charts?
Text in a table comes out as one bullet per cell, reading across each row in turn, so short tables stay readable but lose their grid. Charts are left out completely, titles and labels included, as are pictures, so add a line of text summing up any chart you need in the PDF.
Does it keep my bullet levels?
No. Every paragraph becomes a bullet at the same level, the slide title included, so indented sub-points sit flush with the points above them. The order of the text is kept, which is usually enough to follow, but a heavily nested slide will read as one flat list.
