PPT is the legacy PowerPoint binary format from the 1997-2003 era, requiring compatible presentation software to view. JPG is the most common image format in the world, viewable on any device. Converting PPT to JPG turns each slide of a legacy presentation into a standalone compressed image, making decades-old presentation content instantly accessible to anyone.

As PowerPoint evolves, older PPT files become harder to render correctly. Font substitutions, missing clip art, and changed rendering engines mean that a PPT file from 2001 may look different when opened in PowerPoint 2025. Converting to JPG captures the current visual rendering permanently, ensuring the slides look the same in 2030 as they do today.

JPG images also unlock PPT content for modern platforms. Social media managers can post individual slides, web designers can embed them in pages, and content creators can include them in blog posts — all without touching the PPT file. For repurposing legacy presentation content in modern contexts, JPG is the bridge format.

LibreOffice parses the PPT binary's OLE2 compound structure, extracting slide records, text runs, drawing primitives, and embedded images. Each slide is rendered to a bitmap buffer at the target DPI using Impress's rendering pipeline with text antialiasing and shape rendering. The bitmap is encoded as JPG (JFIF format) with DCT compression at the configured quality level. Each slide produces one numbered JPG file. Legacy PPT effects (dissolve transitions, WordArt, AutoShapes) are rendered in their static final state.

Yes, identical format. JPG is a three-letter extension, JPEG uses four letters. The compression and image data are exactly the same.

At 150 DPI, quality 85%, a typical PPT slide (4:3 ratio) produces a JPG of 80-400 KB depending on content complexity.

Standard clip art and AutoShapes from the PPT era are rendered by LibreOffice's drawing engine. Some very old WMF/EMF embedded objects may render with minor visual differences.

Yes. Macros have no effect on the visual rendering — they are ignored during conversion. The slide images are produced from the visual content only.

Embedded video frames are rendered as static images showing the first frame or placeholder. Video playback is not represented in JPG output.
