PPTM to AVIF conversion is the process of extracting visual content (slides or slide images) from a PPTM presentation file and encoding those visuals into AVIF image files. This converts PowerPoint Macro-Enabled Presentation slides into modern, highly compressed AV1 Image File Format images for web or archive use while preserving visual fidelity and reducing file size.

PPTM files use the MIME type application/vnd.ms-powerpoint.presentation.macroenabled. AVIF files have the MIME type image/avif and are based on the AV1 codec, providing efficient compression of still images. PPTM is typically used for presentations with macros, while AVIF is a next-generation image format favored for web graphics and photo storage due to its superior compression performance.
The AVIF (.AVIF) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like PPTM.

PPTM files are PowerPoint macro-enabled presentations primarily used for editing and presenting slide decks, whereas AVIF is a modern image format optimized for compression and quality. Unlike PPTM, AVIF files are static images, not editable presentations, but they offer significantly smaller file sizes and better web compatibility. Converting PPTM to AVIF is ideal for repurposing slides as high-quality images rather than interactive presentations.
Keep individual exported AVIF images under 1–2 MB for fast web delivery; aim for 200–500 KB per slide for image-heavy presentations.
Preserve quality by exporting slides at a higher DPI (150–300) and using a high AVIF quality preset or lossless mode for graphics-heavy slides.
For large presentations, batch conversion is recommended but process in chunks (20–50 slides) to avoid memory/timeouts.
Note format-specific limits: PPTM can contain macros and embedded media which will not translate into a single AVIF image; AVIF only stores raster image data.
