SDD is the presentation format from StarOffice/StarImpress, predecessor to ODP.
XHTML is HTML reformulated as XML, combining HTML presentation with XML strictness.
FreeFileConvert uses tuned encoding for SDD to XHTML conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload SDD files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized XHTML 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 XHTML audio with dependable progress tracking.
SDD files use StarOffice binary format for presentation slides.
XHTML documents follow XML rules and can be parsed by XML tools.
Upload your presentation file in the SDD format from your device, Dropbox, or Google Drive.
Select XHTML as the output format and click Convert. Adjust optional settings if needed.
Download the converted document file. Each file stays available for up to 5 downloads.
