The PPTX file format is a proprietary XML based file format developed by Microsoft. It is mostly associated with Microsoft office PowerPoint, a closed source slide show presentation application. It is the default format that succeeded the .ppt filename extension from Microsoft PowerPoint 2007 SP1 onwards and is part of the Office Open XML specification. Documents to be saved in the .pptx format are saved as PowerPoint presentations. Because the pptx file format is part of the larger opendocument XML file format, many non-proprietary applications are able to open files saved with the .pptx filename extension.
The bitmap image file format or bmp file for short, is a raster graphics image file. It uses a dot matrix data structure to represent pixelated points of color and to store digital image information. The format optionally supports compression and has wide cross platform support on all the major computer operating systems. Because bmp files are raster graphics files, image resolution is constrained meaning images in this format will not scale without loss in quality. This is in contrast to vector graphics images that can scale to arbitrary resolutions.
FreeFileConvert uses tuned encoding for PPTX to BMP conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload PPTX files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized BMP results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent BMP audio with dependable progress tracking.
The .pptx filename extension is a compressed ZIP archive with an xml directory structure. The format supports macros, charts, embedded media files, and images. It is specified in the open standard ISO/IEC 29500-1:2012. A free compatibility update allows older versions of Microsoft Office PowerPoint such as Office 2003 to open .pptx documents.
Because bmp files can be uncompressed, it is capable of supporting larger file sizes and thus higher resolution and higher quality images. This capability makes bmp files inappropriate for digital distribution via webpages or through bandwidth limited networks. Pixels in a bitmap support deferent color depths from 1 bit of either black or white, to grayscale which is 8 bits, to finally 24 bit RGB giving a possible 16777216 possible colors. Color depth can go as high as 32 bits however this is rarely encountered or needed in practice.
