A .pptm extension file is a macro enabled open XML, Microsoft PowerPoint Presentation file. The presentation pages that are termed as slides comprise of text, images, videos, graphs and other components including media files that are required in a presentation. This feature is especially helpful to create presentations for the academic, marketing and business domains where a large amount of content needs to be stored. The advantage of using the .pptm extension as compared to .pptx is that macros can be executed in files with this extension whereas it is not possible to execute macros in .pptx files even if it has macros in it, apart from that both formats have similar features. Microsoft introduced the Open XML format for PowerPoint presentations in 2007 hence files with this extension cannot be opened with previous PowerPoint versions. However, if a Microsoft Compatibility Pack is installed along with the previous versions, it would be possible to open the files with .pptm 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 PPTM to BMP conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload PPTM 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 PPTM format combines the XML Architecture with the ZIP compression technology to reduce the file size. Images, audios and videos can be opened using the 7-Zip application if a compatible PPTM editor or reader is not installed on the system. PPTM files can be converted to other formats that include PPT, PDF, PNG, PPTX or JPG. It can also be converted to a video format like MP4 or WMV. The recent additions to the presentations include features like inserting music that plays all through the presentation, sound effects to highlight specific slides, designing the presentation to play on its own just like a movie, recording the slide show with a pointer on one hand and narration on the other, repetition and shuffling the order of the slides as per requirement.
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.
