HDR Precision Output

EXR captures floating-point color data well beyond the 8-bit range of standard formats. Slide visuals gain maximum tonal depth for professional post-production work.

VFX Pipeline Ready

OpenEXR is the standard across film, animation, and visual effects studios. Converted PPSM slides integrate directly into Nuke, After Effects, and compositing workflows.

Heavy Lifting in the Cloud

EXR encoding with floating-point precision is computationally demanding. Convertio handles it on cloud servers, delivering results fast without taxing your hardware.

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.

Initial release: January 30, 2007
EXR is a high-dynamic-range raster image format developed by Industrial Light & Magic (ILM) internally since 1999 and publicly released as open-source software in January 2003. OpenEXR was created to meet the demanding requirements of feature film visual effects compositing, where scenes routinely contain extreme brightness ranges — from deep shadows to specular highlights on water, metal, or light sources — that exceed the precision of 8-bit or 16-bit integer formats. EXR stores pixel data in 16-bit floating-point (half) or 32-bit floating-point per channel, providing over 30 stops of dynamic range with smooth precision across the entire luminance spectrum. The format supports an arbitrary number of channels (not just RGBA), tiled and scanline storage, multiple compression methods (lossless ZIP, lossy B44 and DWAA/DWAB for preview quality), multi-part files containing multiple views or layers, and deep pixel data where each pixel stores multiple depth-sorted samples for volumetric effects. One advantage is compositing fidelity: the floating-point precision means that color grading, exposure adjustments, lighting changes, and multi-layer compositing operations produce mathematically correct results without the banding, clipping, or quantization artifacts inherent in integer formats. EXR's adoption as the VFX industry standard is another core strength — it is the default interchange format for Foundry Nuke, Autodesk Flame, Blackmagic Fusion, Adobe After Effects, and every major 3D renderer, and its open-source C++ library is embedded in hundreds of production tools.

Frequently Asked Questions

Why convert PPSM to EXR?

EXR is the industry standard for HDR imagery in film and VFX. Converting slides to EXR lets you integrate presentation graphics into compositing and color grading pipelines.

What software opens EXR?

Adobe Photoshop, After Effects, Nuke, Blender, DaVinci Resolve, and Houdini all handle EXR natively. It is the backbone format of professional visual effects work.

What makes EXR special?

EXR stores floating-point color data with high dynamic range and multiple channels. It captures far more tonal detail than standard 8-bit formats like JPEG or PNG.

Do PPSM macros carry into EXR?

No. EXR is an image-only format designed for pixel data and render passes. All VBA macros from the PPSM are completely stripped during conversion.

Is the conversion free?

Yes — Convertio converts PPSM to EXR at no cost. Premium plans offer expanded limits and priority processing for production-scale workflows.

Are EXR files large?

EXR can produce larger files than standard image formats due to floating-point precision. Built-in compression options like ZIP and PIZ help keep sizes manageable.
