SlideForge

SlideForge is a browser-based PowerPoint template editor built with Next.js, TypeScript, Tailwind CSS, Zustand, JSZip, and PptxGenJS.

It lets you import .pptx files, edit slide content on an interactive canvas, adjust object properties, and export the result as a new PowerPoint presentation.

Getting started

Install dependencies:

npm install

Start the development server:

npm run dev

Open http://localhost:3000 in your browser.

Features

• Import .pptx files directly in the browser
• Slide thumbnails and slide navigation
• Add slides, textboxes, rectangles, and circles
• Drag canvas elements to reposition them
• Double-click text to edit it
• Edit position, size, fill color, and font size in the property panel
• Export edited slides to edited_presentation.pptx
• Client-side processing with no backend required

Sample decks

Example presentations are available in sampleDeck/:

Use the Import button in the editor to load one of these files.
