Deliver Flawless Presentations Without Missing Fonts or Broken Slide Formats

Sending an editable PowerPoint file (.pptx or .ppt) for a high-stakes investor pitch, lecture handout, or client review is risky. If the viewer is on a smartphone, uses a different operating system, or doesn't have your custom brand fonts installed, your presentation can suffer from broken text wrap, overlapping diagrams, and shifted logos.

Converting your PowerPoint presentation into a fixed-layout PDF guarantees that every slide preserves its exact 16:9 widescreen or 4:3 standard aspect ratio, vector icons remain crisp, and color schemes stay true on any device—even if the recipient does not have PowerPoint installed.

Exact Slide Geometry: Widescreen 16:9 & Standard 4:3 Preservation

Generic converters often distort custom slide proportions by forcing widescreen presentations into letterboxed 8.5x11 portrait paper frames. Our engine detects the native bounding canvas of each slide and generates corresponding landscape PDF pages.

When you enter full-screen presentation mode in Acrobat or any PDF viewer, your slides fill the entire monitor edge-to-edge with zero black borders or stretched graphics.

Tip: Supports presentations created in Microsoft PowerPoint, Google Slides, Apple Keynote, and Canva (saved as .pptx).

Tip: Vector shapes, SmartArt graphics, and high-res photography maintain optimal clarity without pixelation.

Zero Cloud Footprint for Sensitive Corporate Strategies

Corporate presentations often contain proprietary roadmaps, non-public earnings metrics, and confidential strategic plans. Handing those files over to remote cloud queues creates unwanted data compliance risk.

JustPDFConverter processes the entire presentation conversion client-side in your web browser. Your slides and business data are never uploaded to remote servers or stored in any database.

Frequently Asked Questions

Everything you need to know about processing files with JustPDFConverter

Will widescreen (16:9) slides look right in the resulting PDF?

Yes! The conversion engine reads the exact slide proportions from your presentation so that widescreen slides stay in widescreen format, filling standard computer monitors and projectors without awkward letterboxing.

Can I convert presentations created in Google Slides or Canva?

Yes! Download your presentation as a .pptx file from Google Slides or Canva, then drop it into our converter to create a crisp, standardized PDF slide deck.

What happens to slide animations and transition effects?

Because PDF is a static document format, each slide is captured in its final visual state. This ensures all text blocks, diagrams, and images are fully visible for easy reading and printing.

Do I need Microsoft PowerPoint installed on my computer?

No. You do not need PowerPoint, Microsoft 365, or any desktop software installed. The conversion is performed entirely inside your web browser.

Is there any watermark or file count limit?

None whatsoever. All converted PDF slide decks are completely free of watermarks, and you can convert as many presentations as you need.
