SDA is the drawing format from StarOffice/StarDraw, predecessor to ODG.
XHTML is HTML reformulated as XML, combining HTML presentation with XML strictness.
FreeFileConvert uses tuned encoding for SDA to XHTML conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload SDA 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.
SDA files use StarOffice binary format for vector drawings.
XHTML documents follow XML rules and can be parsed by XML tools.
Upload your presentation file in the SDA format from your device, Dropbox, or Google Drive.
Select XHTML as the output format and click Convert. Adjust optional settings if needed.
