Frequently Asked Questions

Common questions about the ZeroKB PowerPoint to PDF converter.

Yes. ZeroKB lets you convert a modern PPTX presentation to PDF directly in your browser without requiring a desktop PowerPoint installation.
The conversion in this page is designed to happen locally in your browser. The PPTX file is read by the browser and rendered on your device rather than being sent to a server for conversion.
The converter renders the complete slide to a canvas before placing it in the PDF. This is intended to preserve the visual layout much better than a text-only PPTX extraction method. Exact PowerPoint fidelity can still vary for unsupported Office effects, fonts, animations or media.
No. This page accepts modern .pptx files. If you have an old .ppt presentation, open it in PowerPoint or another compatible office application and save it as .pptx first.
Yes, the page is responsive and the conversion runs in a modern mobile browser. Large presentations may require more memory and processing time on mobile devices.
Choose Original Slide 16:9 when you want the PDF page ratio to match a widescreen presentation. Choose A4 or Letter when you need a standard document page size.
The browser renderer is designed to render common PowerPoint slide elements such as text, images, shapes, tables and supported charts. Results can vary for advanced or unsupported PowerPoint features.
