100% FreeNo UploadNo Sign-upEditable .pptx Output
使用步驟
- Drop PDF: Drag any PDF in. Each page becomes a slide. Multi-page PDFs work the same as single-page — every page yields one slide.
- Pick Mode: 'Editable Slides' mode extracts text via pdfjs-dist and rebuilds native PowerPoint slides you can edit. 'Visual Slides' mode renders each page as an image inside the slide — for designed/scanned PDFs.
- Configure: Set slide size (4:3 standard, 16:9 widescreen, custom). Decide whether to keep original page aspect ratio or normalize to slide ratio. Optionally preserve PDF text positions to slides.
- Convert to PPTX: Click 'Convert'. The tool uses pptxgenjs to assemble slides in your browser via WebAssembly. A 20-page PDF completes in 10-20 seconds.
為何選擇此工具
- 100% Local Processing: Files are processed entirely in your browser using JavaScript — never uploaded to any server.
- No Limits: No file count or file size restrictions. Process as many files as your device can handle.
- No Sign-up: Free forever, no account needed, no email required. Open the page and start.
- Private by Design: Nothing is sent to any server. Close the tab and your files are gone forever.
常見問題
Can I convert a PDF to PowerPoint slides?
Yes — our PDF to PPT tool turns each PDF page into a slide in an editable .pptx file. Choose 'Editable Slides' for text-based PDFs (you can edit text in PowerPoint) or 'Visual Slides' for image-based / scanned PDFs (each page becomes an image inside a slide).
How does the Editable Slides mode work?
We extract text blocks from each PDF page using pdfjs-dist, then rebuild native PowerPoint slides with the same text positioning. The result is a standard .pptx where you can edit text, change fonts, restyle — fully editable in PowerPoint, Keynote, Google Slides, LibreOffice Impress.
What about Visual Slides mode?
For PDFs that are pure images (scans, designed pages, multi-column layouts), Editable mode would lose the visual fidelity. Visual Slides mode renders each page as a high-resolution image embedded in a slide — the slide layout matches the PDF page exactly. Less editable but perfect visual match.
Will my PDF be uploaded?
No. pdfjs-dist + pptxgenjs run entirely in your browser. For confidential presentations, client decks, exam materials — the PDF and resulting .pptx stay on your device.
Does the .pptx work in Microsoft PowerPoint?
Yes — we output standard .pptx files using pptxgenjs. They open in PowerPoint 2007+, Office 365, Google Slides (with conversion), Keynote (with conversion), and LibreOffice Impress. Animations, transitions, and notes are not preserved (we only convert content).
Can I batch convert multiple PDFs?
Yes — drop multiple PDFs and convert them all to .pptx. You get one .pptx per PDF (or one merged .pptx if you enable 'Merge all PDFs into one presentation'). For mixed batch sizes, each file processes independently and downloads separately.
