How Paper Convert Works

3 simple steps in your web browser with zero heavy Revit installations required

01

Upload Model Online

Upload a local copy from Revit 2019 through 2026. For a cloud central model, obtain a detached copy first. Revit 2027 files are not supported yet.

02

Select Target & Convert

Choose your target release. Paper Convert prepares the model for that release while preserving compatible elements.

03

Download & Open Project

Download the resulting file and open directly in your earlier Revit version without encountering the 'saved in a later version' error.

Comprehensive Support for 4 Revit BIM Formats

Full compatibility across project models, component libraries, and company BIM standards

.RVT

Revit Project

Master building models & multi-disciplinary coordination

.RFA

Revit Family

Component libraries: doors, windows, structural framing, MEP equipment

.RTE

Details on security, how conversion works, and licensing

All uploaded files are isolated in temporary scratch containers. Upon completion or after 30 minutes, both input and output files are permanently evicted to free resources and safeguard your design intellectual property.
No. Paper Convert is an independent model conversion platform developed by Paper Engineer. Autodesk and Autodesk Revit are registered trademarks of Autodesk, Inc.
Measured sample files kept 99%+ of elements, not guaranteed for every file. Elements the target version cannot represent are removed and listed in an Excel report. Check the converted model in target Revit.
No. All processing is performed automatically in the cloud, allowing immediate model downgrades from any modern web browser.
100% Free! This is an open community initiative and we never charge any fees. However, if this tool supports your workflow, feel free to buy us a coffee to help fund a more powerful server and inspire new useful tools!
Paper Convert preserves the project's worksets. Because the original central path belonged to a newer release, when opening the model in target Revit: check "Detach from Central" → Open file → "Save As" to establish a new Central Model for your team.
Since this community tool relies on free cloud hosting (Render Free Tier is capped at 512MB RAM and sleeps when idle) to minimize operational costs :D, we designed a smart Hybrid Edge architecture:
• ⚡ When the PC Accelerator is online: Cloudflare Worker routes tasks through Cloudflare Tunnel to leverage full PC RAM and multi-core CPU power, enabling large Revit models to convert rapidly without memory limits.
• ☁️ When the PC is offline: All requests automatically failover to Render Cloud operating 24/7, ensuring the web service remains continuously available at all times.
100% Privacy Guarantee — Zero Data Storage:Rest assured: The system automatically deletes all your files immediately after conversion. We guarantee zero file storage, never inspect, and never collect any of your design or building model data. Learn more in our Privacy Policy and Technical Architecture Docs.
