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.
About downgrading Revit 2027 to Revit 2026
Revit 2026 cannot open a file saved in Revit 2027: a Revit release only opens files from its own version and older ones. Revit Downgrade rewrites the file in the Revit 2026 format, so it opens in Revit 2026 as a normal, editable Revit file, with no IFC or other export in between.
This is a one-version step, 2027 → 2026. Anything Revit 2026 does not know is removed, and every removed element is listed on the result page.
Small files take about a minute; large models take a few minutes.
The converted file opens in Revit 2026 and in any newer Revit, which upgrades it as usual. Save it once in Revit 2026 and it is an ordinary Revit 2026 file from then on.
It works the same for projects (.rvt), project templates (.rte), families (.rfa) and family templates (.rft) saved in Revit 2027, up to 1 GB.
What Revit 2026 does not support
Each Revit release adds new kinds of elements. When a file goes down, elements the older version has no place for are removed, and every one of them is listed on the result page with its ElementId, so you can find it in the original model.
Revit 2027 → Revit 2026
Not in Revit 2026: point, line and area boundary conditions in the new Revit 2027 categories, rebar distribution paths and rebar concrete edges.
Also changes: the "Server Room" space type becomes no space type, and stair riser numbers go back to the size and color settings of Revit 2026.
Other ways to get a Revit 2027 model into Revit 2026
Converting is not the only option. What each one gives the person on Revit 2026:
- A copy from before the upgrade
- If the sender still has the file saved in Revit 2026 or older, it opens as it is, but without the changes made since.
- IFC
- Revit 2027 exports IFC and Revit 2026 links or imports it. Geometry and much of the data arrive, but walls, families and parameters are no longer native, editable Revit elements.
- Installing Revit 2027
- Opens the file as it is, but needs a Revit 2027 license, and anything saved there can no longer be opened by people who stay on Revit 2026.
- Converting the file
- A native Revit 2026 file you keep working on. Elements Revit 2026 has no place for are removed and listed with their ElementIds.

Questions about downgrading Revit files
How do I open a Revit 2027 file in Revit 2026?
Add the file above: Revit 2026 is picked for you. Press Downgrade, then download the converted file and open it in Revit 2026. Nothing to install, no account.
Can Revit 2027 save a file for Revit 2026?
No. Revit 2027 has no Save As older version: every save writes the Revit 2027 format, which Revit 2026 cannot open. Converting the file is the way to get it into Revit 2026.
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
