V18: PowerPoint Engine, Batch Image Convert, and Video Overlays
Better PowerPoint. Batch image convert. Video overlays. AI presentations. V18 is here.
Eighteen releases. Eighteen consecutive Fridays. V18 brings a completely rebuilt PowerPoint rendering engine -- shapes, charts, tables, connectors, embedded fonts, audio, and hyperlinks all render properly now. Batch image conversion lets you convert dozens of images at once, including HEIC files from your iPhone. The video editor gains an overlay editor for adding text and graphics to your videos. And you can now generate entire presentations with AI, complete with design system and color palettes.
What's New in V18
PowerPoint Rendering Engine
PowerPoint files now render with full fidelity. Preset shapes, charts, tables, connectors, embedded fonts, gradient fills, and geometry transforms all display correctly. Audio elements play inline and hyperlinks are clickable. Text inheritance, bullet formatting, and theme colors resolve accurately. Your PPTX files look the way they were designed.
Batch Image Convert
Convert multiple images at once across formats. Select a batch of files, choose your target format, and convert them all in one go. Full HEIC support means you can batch convert iPhone photos to JPG, PNG, or WebP without any extra steps.
Video Overlay Editor
Add text, images, and graphics on top of your videos with the new overlay editor. Position and style overlays visually, then export your video with everything baked in. Great for adding watermarks, titles, or branding to video content.
AI Presentation Generation
Generate complete slide decks with AI. Describe what you need and Diwadi creates a presentation with a cohesive design system, matching color palette, and properly laid out slides. Skip the blank-slide anxiety and start from something polished.
