Pick the AE you have. Drop your .aep, .aet or .ffx files. We spot which version saved each one and convert anything newer so yours opens it. Nothing is uploaded.
No files yet. We’ll show which version each one was saved in.
Each file’s version stamp is read and matched to a known After Effects version, so you can see what it was saved in before anything changes.
Your files never leave your device. Only the first few KB are read, the version stamp is rewritten, and the result goes straight back to you.
The body of your project is never loaded into memory. Multi-GB projects convert as fast as small ones.
A new file is made with a suffix like _AE2022. Check exactly which bytes changed under “Header details”.
This changes the version stamp that makes older After Effects refuse a file. It cannot add features an older version does not have. If the project uses effects, layer types or expressions that only exist in the newer version, those parts can come in blank, missing, or fail to load. Presets (.ffx) and simpler projects convert most reliably.
Then it already opens, and we’ll tell you so instead of touching it.
The file was probably saved in a version we haven’t added yet. Conversion still works because it only needs the version you picked.
That version is still being added. Check back shortly.
Your original is never modified, but keep it anyway. Converted files are for opening in an older version, so save your work from there as a fresh file.
.aepx is an XML text version of a project, which is a different format. Open it in After Effects and save as .aep, then convert.
Same engine as this page, so your files are still patched on your own computer and never uploaded. The app adds folders, a watch folder, auto-detection and a right-click shortcut.
This page stays free and keeps working. The app is for when you have more than a handful of files, or you convert often.

Up to 30 files in one run when you’re signed in, 10 when you’re not. The browser stops at 10.
The app looks at which After Effects versions are installed and picks one, so there’s no menu to get wrong.
Drop a folder and every .aep, .aet and .ffx inside it, subfolders too, is converted. Your folder layout is kept.
Point it at your downloads or a scene pack folder. Anything that lands there is converted once it finishes copying, and you get a notification.
Right-click a project, preset or folder and choose “Convert with PVNTISS”. After Effects still opens its own files as usual.
Tick one box and converted .ffx presets are installed into After Effects for you.
No. The app works signed out with the same 10-file limit as this page. Sign in with your PVNTISS account to raise it to 30 files and use the watch folder.
No. Just like this page, the version stamp is rewritten on your computer. Your files never leave it, and the original is left untouched.
That can happen with apps from outside an app store. On Windows, choose “More info” then “Run anyway”. On Mac, right-click the app, choose Open, then confirm. Only do this with the file you downloaded from here.
The same rules apply as in the browser. Converting changes the version stamp, but it can’t add features an older After Effects doesn’t have. Presets and simpler projects convert most reliably.
