Revit Downgrade is free and runs on a small server I pay for myself, so files are limited to 1 GB. Need to convert larger files, or a private version for your company? Get in touch, my contact details are at the bottom of the page. If you find this project useful and would like to help upgrade the server for larger files and faster conversions, you can reach me there too.

Questions about downgrading Revit files

How do I downgrade a Revit file to an older version?

Add your file above, choose the Revit version you need and press Downgrade, then download the converted file and open it in that older Revit. For example, a Revit 2026 model can be opened in Revit 2024. Any file from Revit 2023 to 2027 can go down to Revit 2022, with nothing to install.

Can Revit save a file to an older version?

No. Revit only upgrades: it opens files from older versions and always saves in its own version. There is no "Save As older version" in Revit, which is why this tool exists.

Which files and versions are supported?

Projects (.rvt), project templates (.rte), families (.rfa) and family templates (.rft) saved in Revit 2023, 2024, 2025, 2026 or 2027, converted to any older version down to Revit 2022. Files up to 1 GB.

Will I lose anything?

Elements that the older Revit does not know, such as features added in a newer version, are removed. After the conversion you see the full list of removed elements with their ElementIds and can download it as CSV.

Can I backsave a Revit file?

Not in Revit itself: Revit has no backsave or "save to previous version" command. Revit Downgrade does the backsave online instead, for files from Revit 2023 to 2027, down to Revit 2022.

Can I downgrade a workshared (central) model?

Yes. Worksets and worksharing are kept. Convert the central model like any other file. A cloud model in Autodesk Docs has to be saved as a local .rvt file first.

What about families and linked models?

Families loaded in a model are converted with it, so there is nothing extra to do. A linked Revit model is a separate file, so convert it on its own, to the same version. The same goes for a family file (.rfa) you want to load later.

Is my file safe?

Your original file is deleted as soon as the conversion finishes, and the converted file after 2 hours. Files are never shared. If a conversion fails, the file is kept for up to 7 days to fix the problem, without you ticking anything, and you can delete it at once with Delete my file. After that the server keeps only the error message, not the file. The website and server code that handles files is open source; the conversion engine itself is closed source. How files are handled
