Why are my brand fonts substituted with default fonts?

PPTX is the default PowerPoint format since PowerPoint 2007, built on Office Open XML and used wherever slides are made - PowerPoint 365, Keynote, Google Slides (on export), LibreOffice Impress. Sales engineers presenting pitch decks, conference speakers, university lecturers, and product managers building roadmap reviews all create PPTX files daily. Converting PPTX to JPG renders each slide as a flat image - the format social media platforms actually accept for carousels, the format LinkedIn document posts secretly rasterize behind the scenes, and the format conference organizers request when collecting speaker decks for archival.

Slide-to-JPG conversion is the most predictable office-to-image workflow because slides are already paginated by design - one slide becomes one JPG, in slide order. Speaker notes, hidden slides, and section dividers are excluded unless explicitly included. Animations, transitions, and embedded video render as their first frame (animations cannot be captured as static images). Embedded charts, SmartArt, and shapes all render as their visual state at slide-open. If your deck uses real-time linked data (a chart pulling from an Excel sheet), the JPG captures whatever was last saved into the PPTX, not a fresh fetch.

PPTX files run 200KB-200MB. A minimal text-only 10-slider is usually under 500KB; a 60-slide investor deck with embedded high-res photography and screen recordings can easily exceed 100MB. JPG output ranges 200KB-2MB per slide depending on DPI and visual complexity. For 16:9 widescreen decks (the modern default), JPGs render at 1920x1080 at high DPI; 4:3 legacy decks render 1024x768. For legacy PowerPoint, see our PPT to JPG tool. For macro-enabled decks, use PPTM to JPG.

Reasons to convert PPTX to JPG usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts JPG uploads.
• You need a feature unique to JPG (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that PPTX doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the PPTX → JPG tool on jpg.now.
2. Drag your PPTX file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to JPG. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• Embed all fonts in PowerPoint before exporting (File - Options - Save - Embed fonts in the file) so brand typography renders correctly rather than falling back to system substitutes.
• For LinkedIn carousel posts, export at exactly 1080x1080 (square) or 1080x1350 (portrait) - resize your slide masters first, then convert.
• Animations only render as the final state - if your slide reveals bullets one at a time, the JPG shows all bullets visible. Design with this end-state in mind.
• Hidden slides are skipped by default - useful for excluding backup slides, appendix content, or speaker-only notes that should not be in the JPG export.
• Convert PPTX to PDF first via PowerPoint's File - Save As - PDF if you need vector-quality text in the JPG at small font sizes - direct rasterization can soften tight kerning.
