About formats

PPT is the binary file format of Microsoft PowerPoint, the presentation software first released on April 20, 1987 for the Apple Macintosh and later ported to Windows. The PPT format stores presentations as OLE2 compound documents — a structured binary container developed by Microsoft that organizes slides, text content, images, charts, animations, transitions, speaker notes, and embedded objects across multiple internal streams. Each slide is composed of shape records describing text boxes, auto-shapes, images, tables, and other elements with associated formatting properties including fonts, colors, positioning, and animation sequences. The format evolved substantially through multiple PowerPoint versions, with the PowerPoint 97 release establishing the compound document structure that remained standard through PowerPoint 2003. One advantage is universal recognition — PPT files are understood by virtually every presentation application across all platforms, from Microsoft Office to LibreOffice Impress, Google Slides, and Apple Keynote, making it one of the most portable document formats ever created. The format's mature feature set is another strength: PPT files support complex slide masters, custom animations with timing sequences, embedded multimedia, OLE-linked objects, and VBA macros for automation. Although Microsoft introduced the XML-based PPTX format with Office 2007, the binary PPT format remains widely encountered in archived presentations, corporate document repositories, and organizations that maintain compatibility with older PowerPoint versions.
Developer: Microsoft
Initial release: April 20, 1987
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.
Initial release: January 2003

Frequently Asked Questions

Why convert PPT to EXR?

EXR is the industry standard for HDR imagery in visual effects and 3D rendering. It captures an extended luminance range that standard formats cannot represent.

What software opens EXR files?

Adobe Photoshop, Nuke, Blender, DaVinci Resolve, and most VFX compositing tools read EXR natively. GIMP also supports it through plugins.

Is EXR overkill for simple slides?

For general sharing, yes — JPEG or PNG would suffice. EXR becomes valuable when slide visuals feed into VFX pipelines, environment mapping, or compositing work.

Does EXR preserve color accuracy?

EXR stores floating-point color data per channel, preserving far more color precision and dynamic range than 8-bit formats like PNG or BMP.

Is PPT to EXR conversion free?

Standard PPT to EXR conversions are free on Convertio. Premium plans offer higher limits for large presentations or batch workflows.
