About formats

PPSM (PowerPoint Slideshow with Macros) is a macro-enabled slideshow format in Microsoft PowerPoint, introduced with Office 2007 as part of the Office Open XML family. PPSM combines the auto-play slideshow behavior of PPSX with the VBA macro capabilities of PPTM — opening a PPSM file launches it directly into full-screen presentation mode while allowing embedded macro code to execute during the slideshow. The format is structurally a ZIP archive containing the same XML slide parts as other OOXML presentation formats, plus a vbaProject.bin stream housing the VBA project. This combination is particularly valuable for interactive presentations: macro-driven slideshows can respond to user input, navigate non-linearly between sections, query external databases, update content in real time, and log audience responses during training or assessment sessions. One advantage is interactive presentation capability — PPSM enables quiz-style presentations where clicking answer buttons triggers immediate scoring feedback, branching paths, or data recording, all invisible to the audience. The macro-enabled slideshow format also supports self-contained automation: a PPSM file can run initialization routines on launch, configure the display environment, and clean up resources on exit without any manual intervention. As with all macro-enabled Office Open XML formats, the distinct .ppsm extension helps administrators enforce security policies that differentiate between trusted macro content and standard presentations. PPSM is supported exclusively in Microsoft PowerPoint desktop editions.

HEIF (High Efficiency Image File Format) is a container format for images and image sequences standardized by the Moving Picture Experts Group as ISO/IEC 23008-12, first published in 2015. HEIF is built on the ISO Base Media File Format (ISOBMFF, the same container used for MP4 video), providing a flexible structure that can hold single images, image collections, image sequences (like animations or bursts), and derived images with non-destructive editing operations. The container is codec-agnostic — while the most common implementation pairs HEIF with HEVC/H.265 compression (branded as HEIC by Apple), the standard also accommodates AV1 compression (creating the AVIF variant), H.266/VVC, and other future codecs. HEIF supports features that JPEG lacks: 10-bit and 12-bit color depth, wide color gamuts (Display P3, BT.2020), lossless compression, alpha transparency, depth maps, thumbnail images, and Exif/XMP metadata — all within a single file. Auxiliary image items can store computational photography data like depth maps, HDR gain maps, and semantic segmentation masks. One advantage is the format's future-proof architecture: by separating the container from the codec, HEIF can adopt newer, more efficient compression technologies without changing the file structure, metadata handling, or application-level APIs. The substantial compression improvement over JPEG is another core strength — HEVC-based HEIF typically achieves 40-50% file size reduction compared to JPEG at the same visual quality, beneficial for storage and bandwidth. HEIF is supported by Apple's ecosystem (iOS, macOS), Windows 10/11, Android 10+, GIMP, ImageMagick, and Adobe products.

Frequently Asked Questions

Why convert PPSM to HEIF?

HEIF is the modern successor to JPEG — sharper images at smaller sizes. Converting slides to HEIF future-proofs your visual content with next-generation compression.

What programs support HEIF?

Apple devices support HEIF natively. Windows handles it with the HEIF extension. Adobe Photoshop, Affinity Photo, and GIMP can all open and edit HEIF files.

Is HEIF the same as HEIC?

HEIF is the container format; HEIC specifically uses HEVC compression. Both terms are often used interchangeably for Apple-style high-efficiency images.

Do macros survive the HEIF conversion?

No — HEIF stores image data only. All VBA macros and executable code from the PPSM source are fully removed during the conversion process.

Is this service free?

Convertio converts PPSM to HEIF for free. Premium subscriptions offer higher volume caps and priority processing for professional workflows.

Does HEIF support transparency?

Yes — HEIF supports alpha channel transparency. Slide elements with transparent areas can be preserved in the converted output.
