About PPT to PDF
PPT to PDF is a free, browser-based converter that transforms PowerPoint PPTX presentation files into PDF documents by extracting the text content from each slide. It uses JSZip to unpack the PPTX file format (which is a ZIP archive containing XML files), parses the slide XML to extract text from all <a:t> tags, and uses jsPDF to render each slide's text onto a corresponding PDF page, all running entirely in your browser.
The tool is useful for sharing presentation content in a universally readable, non-editable format, creating text-based summaries of presentations for archiving or distribution, and converting PPTX files when PowerPoint or other presentation software is not available. It also supports Korean and other languages through a bundled Korean font loader for the jsPDF library.
Technically, the converter reads the PPTX file as an ArrayBuffer and loads it with JSZip. It scans the ZIP entries for files matching the pattern ppt/slides/slideN.xml and sorts them numerically. For each slide, it parses the XML with regex to extract all <a:t> text node contents. A new landscape A4 jsPDF page is created for each slide, the slide number is printed in the header, and extracted text strings are laid out line by line with automatic word wrapping using splitTextToSize(). The Korean font is loaded via a separate utility before rendering begins.
Key Features
- Extracts text from all PPTX slides by parsing <a:t> XML nodes in each slide file
- Each slide is mapped to one landscape A4 PDF page with header showing slide number
- Automatic text wrapping with splitTextToSize() to fit content within page margins
- Supports Korean text through a bundled Korean font loaded into the jsPDF instance
- Slide files are sorted numerically to preserve presentation order in the output PDF
- 100% client-side processing via JSZip and jsPDF — PPTX files never leave your browser
- Output PDF filename matches the original PPTX filename automatically
- Supports PPTX files up to 50 MB with no account or software installation required
Frequently Asked Questions
How does PPT to PDF conversion work in the browser?
The tool reads the PPTX file as a ZIP archive using JSZip, finds each slide XML file (ppt/slides/slide1.xml, slide2.xml, etc.), extracts all text nodes using regex on the <a:t> tags, and renders the text onto jsPDF pages. Each slide becomes one landscape A4 PDF page.
Will the converted PDF look like the original PowerPoint presentation?
No. The tool extracts text content only and does not reproduce the visual design. Slide backgrounds, images, shapes, animations, transition effects, and precise font styling are not included. The output is a text-only PDF with slide number headers, useful for content review or archiving.
Does this support .ppt files (older PowerPoint format)?
No. The tool only supports the modern .pptx format, which is a ZIP-based XML format. Older binary .ppt files have a completely different structure and are not compatible with this converter. You can save .ppt files as .pptx in PowerPoint before using this tool.
How is Korean text handled in the output PDF?
The tool loads a Korean font into the jsPDF instance before rendering begins. This allows Korean characters from the PPTX to be rendered correctly in the PDF. Without this font, Korean text would appear as empty boxes or question marks in the PDF output.
What happens if a slide has no text?
If a slide contains no <a:t> text nodes (for example, a slide with only images or shapes), the tool displays "(텍스트 없음)" — "no text" in Korean — on that slide's PDF page. The slide is still included in the output to preserve slide count and order.
Is the PPTX file uploaded to a server during conversion?
No. JSZip parses the PPTX file structure and jsPDF generates the PDF entirely inside your browser using JavaScript. Your presentation file is never transmitted over the internet. All processing happens in browser memory and the PDF is downloaded directly to your device.
Can I convert a PPTX with many slides?
Yes. The tool processes all slides sequentially regardless of count, up to the 50 MB file size limit. There is no slide count restriction. Processing is typically fast since only text extraction and basic PDF rendering are performed, without image or graphics rendering.
Why is text missing from some slides in the PDF?
Text is extracted specifically from <a:t> XML elements inside the slide XML. Text stored in charts, embedded objects, SmartArt nodes, or content types other than standard text boxes may not be captured by the regex-based extraction. Additionally, text in master slides or layouts is not extracted — only content from the individual slide XML files.
