How to Convert PPT to PDF

01

Upload Your PPTX File

Drag and drop a PowerPoint .pptx file, or click "Choose PPTX File". The file is read directly in your browser using JSZip — no upload to any server. Microsoft PowerPoint is not required.

02

Choose Quality Settings

Select the PDF page size (widescreen, A4, Letter), render scale for image sharpness, and JPEG quality. Higher render scale produces sharper text and images in the PDF at the cost of file size.

03

Download Your PDF

Click Convert — each slide is rendered to a canvas, then assembled into a multi-page PDF. Preview all slides before downloading. The PDF downloads automatically.

Why Use This PPT to PDF Converter?

100% Private — No Upload

Your PPTX file is never uploaded to any server. JSZip reads and processes the file locally in your browser — no third-party access ever.

No Microsoft Office Required

Process PowerPoint files directly without any Office installation. Works on any device with a modern browser — no plugins, extensions, or software downloads.

Slide Preview Thumbnails

Every converted slide is displayed as a thumbnail before you download. Review the output, then download the complete PDF or individual slide pages.

Background & Image Extraction

Slide backgrounds (solid colours and gradient fills), embedded images, shape fills, and text content are all extracted from the PPTX XML and rendered faithfully.

Multiple Page Sizes

Choose Widescreen (16:9), A4 Landscape, Letter, or Standard 4:3. Widescreen is recommended for modern presentations to preserve slide proportions.

Adjustable Quality & Scale

Control JPEG quality (60–100%) and canvas render scale (1×, 1.5×, 2×) to balance file size versus sharpness. 2× scale produces near-retina quality PDF output.

Frequently Asked Questions

Do I need Microsoft PowerPoint or Office installed?
No. This converter processes PPTX files directly in your browser using JSZip to parse the file structure. Microsoft PowerPoint, Office 365, or any other Office suite is not required. It works on any modern browser on any device.
What PowerPoint file formats are supported?
The converter supports .pptx — the PowerPoint Open XML format used by PowerPoint 2007 and later. Legacy .ppt files (PowerPoint 97–2003 binary format) are not supported because they use a proprietary binary structure. To convert a .ppt file, open it in PowerPoint or LibreOffice Impress and save or export it as .pptx first.
How does browser-based PPTX conversion work?
PPTX files are ZIP archives containing XML files and embedded media. The converter uses JSZip to extract the file contents, then parses the slide XML to read background colours, gradient fills, embedded images, text boxes, shape fills, and slide dimensions. Each slide is rendered onto an HTML5 Canvas element, then all canvas pages are assembled into a PDF using jsPDF.
Is my PowerPoint file private?
100% private. Your PPTX file never leaves your device or gets uploaded to any server. All processing happens locally in your browser. No third party can access your presentations, your data, or your content at any point.
Will all slide elements be converted accurately?
The converter extracts and renders: slide background colours and gradients, embedded images (JPEG, PNG), text boxes with content, solid shape fills, and slide titles. Complex elements like custom fonts (system fonts are substituted), SmartArt diagrams, charts, 3D effects, and animations are approximated or simplified. For pixel-perfect fidelity, use Microsoft PowerPoint's built-in "Save as PDF" feature.
What should I choose for page size — Widescreen or A4?
Widescreen (16:9) — Best for modern presentations. The PDF page matches the slide aspect ratio exactly, so no letterboxing or scaling occurs. A4 Landscape — Use this if you need standard paper-size PDFs for printing. The slides will be scaled to fit the A4 page with possible thin borders.
