Downgrade Premiere Pro Projects (.prproj)
Need a reliable Premiere downgrader? Encountered the error "This project was saved in a newer version of Premiere Pro and cannot be opened"? CC Downgrader automatically decompresses the GZIP XML binary of your .prproj file and patches internal version IDs, enabling backward compatibility with older Premiere Pro releases.
Downgrade After Effects Projects (.aep / .aepx)
Need to open a 2026 or 2025 After Effects project in AE 2024 or 2023? Our tool safely navigates the RIFX binary chunk hierarchy to patch version signatures directly in your browser, maintaining composition integrity without corrupting project assets.
100% Secure & Client-Side Processing
Unlike other converters that upload your project files to third-party servers, CC Downgrader processes everything locally in your web browser. Your video edits, media paths, and proprietary project assets never leave your machine.
