After Effects compatibility

AEP Downgrader

An AEP downgrader helps when a project was saved in a newer version of After Effects but needs to be opened on an older workstation. This page targets that exact workflow and links to the local browser-based converter.

Downgrade an AEP file

What an AEP downgrader changes

After Effects project files include version signatures and compatibility data. The converter rewrites those fields for a selected target version while keeping the original project untouched.

When to use it

Use it for hand-offs, archive projects, remote collaborators with older AE versions, or machines that cannot upgrade to the latest Creative Cloud release.

Privacy by default

The conversion engine runs in browser memory. Your .aep file is not uploaded to a server, which is useful for client work and unreleased video projects.

Frequently Asked Questions

Is an AEP downgrade guaranteed?+

No. Newer-only effects, properties or plugins may still fail in older AE versions, but a structured rewrite is safer than patching one byte.

Does it support AEPX?+

No. The tool is focused on binary .aep project files.
