PPTX to ODP questions
Short answers about limits, privacy, and keeping the converted file.
Will my slides look the same in ODP?
Most slides transfer closely. Fonts that are not installed on the viewing computer, complex graphics, and animations are the most common differences.
Is the PPTX to ODP converter free?
Yes. Without an account you can convert up to 10 files a day, 2 at a time, up to 25 MB each. A free account adds monthly conversion credits and larger files.
How long are my files kept?
Guest uploads and results are deleted automatically after 1 hour. Conversions stay temporary when you are signed in too, unless you save a result to your workspace.
Can I get a permanent link to the ODP file?
Yes. Save the result to a SteadyLink workspace and it gets a stable link. If you make a new version later, replace the file and the link stays the same.
