PowerPoint to PDF
Render an unencrypted PPTX slide deck into one local PDF page per slide, including common shapes, text, images, tables, charts, themes, and backgrounds.
Processed in this browserOne unencrypted .pptx file up to 20 MB, 3,000 package parts, 180 MB expanded data, and 120 slides. Output is limited to 100 MB.
PPTX - 20 MB - 120 slides
No file upload
This operation runs with browser APIs. Nirmion receives catalogue requests, not the selected source bytes.
Original stays unchanged
The converter creates a separately named output. It never writes back into the source file.
Bounded work

Plain-language method
How PowerPoint to PDF works
The browser validates the OOXML archive, reconstructs every slide through a bounded PowerPoint renderer, waits for slide resources, captures the slide surface, and writes one separate PDF page for each slide.
- 01Choose a valid source
Use a current .pptx with saved charts and embedded or locally available fonts. Password-protected decks and legacy .ppt files are not supported.
- 02Review the conversion choices
Use standard on mobile or for image-heavy decks. High is useful for small labels when the source stays comfortably below the limits.
- 03Inspect the separate result
The _nirmion_tools.pdf follows slide order and aspect ratio. Speaker notes, animations, transitions, audio, video playback, editable objects, and interactive links are not carried into static PDF pages.
Useful when
Practical jobs this tool handles
- Send a static deck review without a cloud converter.
- Archive the visible state of an approved presentation.
- Create a print-friendly slide handout source.
Before converting
Check the source and destination rules
- Review custom fonts and chart labels.
- Confirm hidden slides should remain in the source.
- Compare every PDF page before distribution.
Know the boundary
Know what the destination format cannot keep
PowerPoint remains the reference renderer. SmartArt fallbacks, EMF or WMF artwork, unsupported effects, external media, and font substitution can differ. Use PowerPoint export for contractual or pixel-exact delivery.
Quick answers
Questions before you convert
The conversion contract is deliberately explicit.
Are animations preserved?
No. Each slide becomes one static PDF page.
Are speaker notes included?
No. This route converts visible slide surfaces only.
Does it upload the deck?
No. PPTX parsing, rendering, capture, and PDF creation run in this browser.
