Full-Color Multi-Frame

MNG delivers 24-bit color depth with alpha transparency — far exceeding GIF limitations. Each slide becomes a high-quality frame in a multi-image container.

No Macros, No Risk

PPSM macros raise security flags with recipients. MNG output is a clean image container — share multi-frame slide visuals without any executable code concerns.

Slides to Frames

Multiple PPSM slides convert into sequential MNG frames in one operation. Produce animated or multi-frame image sets from entire presentations efficiently.

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.

MNG (Multiple-image Network Graphics) is an animation and multiple-image format designed as the animated counterpart to PNG, with its specification reaching version 1.0 on January 31, 2001. Developed by Glenn Randers-Pehrson and members of the PNG development community, MNG extends PNG's capabilities with support for frame-based animation sequences, slide shows, complex sprite overlays, and JNG (JPEG Network Graphics) frames for lossy compression of photographic content within the same container. An MNG file consists of a series of chunks (following PNG's chunk-based architecture): MHDR and MEND chunks bookend the datastream, with embedded PNG or JNG images as individual frames and control chunks (DEFI, FRAM, LOOP, ENDL, TERM, BACK, BASI, CLON, PAST, DISC, SHOW) directing playback timing, looping behavior, layer compositing, and memory management. The format supports both full-frame replacement and delta (difference) updates for efficient encoding of animations with static backgrounds, as well as object-based animation where sprites are defined once and repositioned across frames. One advantage is technical sophistication: MNG provides a level of animation control that GIF and APNG cannot match — frame-accurate timing, nested loops, conditional branches, interframe compression, and mixed lossy/lossless content within a single animation. The PNG-based foundation ensures lossless quality with full alpha transparency for each frame. MNG is supported by ImageMagick, GIMP, and various media players, though browser support was limited, which led to APNG's emergence as a simpler alternative for web animation.

Frequently Asked Questions

Why convert PPSM to MNG?

MNG combines the quality of PNG with multi-frame capability. Converting slides to MNG produces lossless animated or sequential images without the color limitations of GIF.

What programs open MNG?

IrfanView, XnView, Konqueror, and ImageMagick support MNG format. Some specialized web and animation tools also handle MNG, though browser support is limited.

How is MNG different from GIF?

MNG supports full 24-bit color and alpha transparency — unlike GIF, which is limited to 256 colors. MNG also offers better compression and richer animation features.

Do macros transfer to MNG?

No — MNG is a pure image container format. All VBA macros from the original PPSM presentation are completely stripped during the conversion.

Is this converter free?

Yes — Convertio converts PPSM to MNG at no cost. Premium plans provide higher file size limits and batch processing for larger workloads.

Is MNG widely supported?

MNG has limited browser support compared to GIF or APNG, but it is well-supported by desktop image viewers and professional imaging tools for offline use.
