What happens when you convert PPT to PDF
- The PPT is opened by LibreOffice, the open-source office suite, on our conversion server and exported to PDF with its layout: one page per slide, with the text, images, shapes and charts as they appear on the slide.
- A PDF cannot play animations, transitions or embedded video, so each slide shows its final state. Speaker notes are not included.
- Where the document uses a font our server does not have, a metric-compatible one is used instead: Carlito for Calibri, Caladea for Cambria and Liberation fonts for Arial, Times New Roman and Courier New, so line breaks stay where they were. Unusual or decorative fonts may look different.
- Password-protected documents cannot be converted, because they cannot be opened without the password.
- This conversion runs on our server: the file is uploaded, converted, and deleted together with the result as soon as the result has been sent back to you. Nothing is kept. Files up to 25 MB are accepted.
How to convert PPT to PDF online
- Press "Choose PPT files" and select one or more files, or drag them onto the box. Files up to 25 MB each can be converted.
- There are no settings to choose: the converter keeps everything the target format can hold.
- Press "Convert to PDF". The file is uploaded to our conversion server, converted in a few seconds, and deleted together with the result as soon as the result is sent back.
- Save each PDF with its download button. Our server has already deleted both your PPT and the PDF by then.
Why convert PPT to PDF?
PPT files usually come from older presentations and slide decks from legacy systems. People convert them to PDF because a PDF looks the same on every device and is what forms, portals and printers ask for.
In short, PPT is good at what it was made for, and PDF is the more practical choice when the file has to open, upload or print somewhere else. PPT opens in PowerPoint, Google Slides, Keynote and LibreOffice Impress, while PDF opens in every browser's built-in viewer.

Best settings for PPT to PDF
There are no settings: each slide becomes one PDF page at its own size, in slide order. Hidden slides are skipped, as they are when you present.
If a font looks different in the PDF, the PPT uses a font our server does not have. Embedding fonts when you save the presentation, or exporting to PDF from PowerPoint or Keynote yourself, keeps the exact typeface.

About PPT and PDF files
What is a PPT file?
PPT is the binary PowerPoint format used before 2007. Current versions of PowerPoint still open it, but save new presentations as PPTX.
What is a PDF file?
A PDF fixes the layout of every page so it looks the same on any device. Converting a PDF to an image renders each page to pixels; converting an image to PDF wraps it as a page.
PPT to PDF not working? Common problems
- "Files up to 25 MB can be converted." Server conversions have a size limit. Compress the images in the document, or split it, and try again.
- "The conversion took too long and was stopped." Very long or complex documents can exceed the time limit. Split the document and convert the parts.
- The document will not convert. It may be password protected, damaged, or saved in a newer or unusual version of the format.
Convert PPT to PDF from the command line
This page uses LibreOffice. Installed on your computer, it converts from the command line without opening a window:
soffice --headless --convert-to pdf input.pptConverting on your own computer keeps the file entirely local, which is worth it for very large or very sensitive documents. For everything else, the converter on this page does it without installing anything.
PPT to PDF converter FAQ
Will I lose quality converting PPT to PDF?
The PDF looks like the PPT printed: text stays sharp and selectable, and images keep their resolution. Fonts our server lacks are replaced with close equivalents, which can change the look of unusual fonts.
Why is the PDF a different size from the PPT?
A PDF embeds the fonts and images it uses, so it may be larger or smaller than the PPT depending on its pictures. Text-only documents usually make small PDFs.
Are my PPT files uploaded?
Yes, for this conversion. A faithful PPT to PDF conversion needs LibreOffice, the open-source office suite, which cannot run in a browser. The file travels over an encrypted connection, is converted in a private temporary folder, and is deleted together with the PDF as soon as the result has been sent back to you. We do not keep, read or share it.
Can I convert several PPT files to PDF at once?
Yes. Select or drop as many files as you like; they are converted one after another and each gets its own download button.
How do I open a PDF file?
PDF opens in every browser's built-in viewer. PDF is common for documents, forms, invoices and print-ready files.
Is this PPT to PDF converter free?
Yes. There is no sign-up and no watermark. Because this conversion uses our server, there is a fair-use limit of 25 MB per file and a number of files per hour, which stops the service being overloaded.
Can I convert PPT to PDF on my phone?
Yes. It works in Safari on iPhone and iPad and in Chrome on Android. The conversion happens on our server, so it is as fast on a phone as on a computer; the PDF is saved to your Downloads folder.
