How to: PPTX to PDF Converter
- Select one or more PPTX files (or a ZIP).
- Choose one combined PDF or one PDF per file.
- Click Start and download the PDF.
Fileopia turns PPTX slide decks into PDFs that open identically on every device – ideal for sharing, printing or uploading to portals that only accept PDF. Everything happens locally in your browser.
Common uses
- Send a deck or report to someone without the original software.
- Upload to job, university or government portals that require PDF.
- Print handouts reliably without layout shifts.
- Archive documents in a format that will open in 20 years.
Tips for best results
- Embed or use common fonts in the original for the closest match.
- Combine several files into one PDF with bookmarks for easy navigation.
- Use Compress PDF afterwards if the file must be under an email limit.
How it works
Each slide is rendered at 1920 px with its layout and master (logos, backgrounds, placeholder positions and text sizes) and saved as a PDF page. Text is drawn into the slide image, so the PDF looks exactly like the slides but text is not selectable – run OCR PDF afterwards for searchable text. Charts, SmartArt, animations, transitions, embedded video and EMF/WMF clip-art are not rendered; gradients are approximated with a solid colour.
Compared with iLovePDF, Smallpdf and Adobe
Those services upload your file to their servers and limit free use (Smallpdf: a couple of tasks per day; Sejda: 3 tasks per hour and 50 MB; Adobe: sign-in for most conversions). Fileopia converts locally with no account and no limits.

Frequently asked questions
How do I convert PPTX to PDF without Office?
Drop the file here and press Start – Fileopia reads the PPTX inside your browser, so you don’t need PowerPoint, LibreOffice or any install.
Are my files uploaded?
No. Conversion runs entirely on your device; confidential decks and sheets never leave it.
What is preserved?
Each slide is rendered at 1920 px with its layout and master (logos, backgrounds, placeholder positions and text sizes) and saved as a PDF page.
What are the limits?
Text is drawn into the slide image, so the PDF looks exactly like the slides but text is not selectable – run OCR PDF afterwards for searchable text. Charts, SmartArt, animations, transitions, embedded video and EMF/WMF clip-art are not rendered; gradients are approximated with a solid colour.
Can I convert several files at once?
Yes – combine them into one PDF with a bookmark per file, or get one PDF each in a ZIP.
Is it free?
Yes – no sign-up, no watermark, no daily task limits.
Can I convert old .ppt files?
Not yet – legacy binary .ppt needs to be saved as .pptx first (PowerPoint, Keynote, Google Slides or LibreOffice can do it).
Does it work on phones?
Yes, in any modern mobile browser, though big files are faster on a computer.
Does it support non-Latin text?
Yes – slides are drawn with your system fonts, so Arabic, Hebrew, Chinese, Japanese, Korean and Indic scripts render correctly.
Is PPTX to PDF Converter really free?
Yes. Every tool on Fileopia is 100% free with no file limits, no sign-up and no watermarks. The site is supported by unobtrusive ads.
Are my files uploaded to a server?
No. Fileopia processes your files directly in your browser using JavaScript. Your documents never leave your device, so they stay completely private.
Does it work on mobile?
Yes. Fileopia works in any modern browser on Android, iPhone, iPad, Windows, Mac and Linux.
