Edit Unity game saves online — JSON, base64-wrapped JSON, .NET binary (NRBF) and Easy Save 3 (.es3), encrypted or not. Change currency, levels and unlock flags in the browser.

Try the demo first

Unity games store progress in whatever format the developer chose — JSON, base64-wrapped JSON, or .NET binary. Upload the save and the format is worked out from the file contents, then shown as a tree you can search and edit.

How to edit a Unity save

Find the save in the Unity persistent data folder for your game.
Upload it — .dat, .data, .sav, .json or .es3 all work.
Search for the value you want and edit it, keeping its type.
Download the file and put it back under the original name.

What you can change

Where the saves are stored

Unity writes to a per-game persistent data folder: on Windows %USERPROFILE%\AppData\LocalLow\<Company>\<Game>, on macOS ~/Library/Application Support/<Company>/<Game>, on Linux ~/.config/unity3d/<Company>/<Game>. Company and game names come from the project settings, so they may not match the store listing.

What the format actually is

Unity saves are whatever the developer serialised. JSON is plain text and the easiest case; base64 is that same JSON with one wrapper on top; NRBF is the .NET binary format, a typed object graph rather than text. Easy Save 3 writes JSON with a few quirks of its own, often encrypted and sometimes compressed, and it goes back in exactly that form. The editor decodes each into the same browsable tree, so the underlying format mostly stops mattering once the file opens.

Warning:Easy Save 3 files (.es3) are usually encrypted with a password the developer chose. We try every password published for such games. When none of them opens your save, the editor asks you for the password, which then has to come from the game itself. PlayerPrefs is also not a save file: on Windows it lives in the registry rather than on disk.

Questions

Can you open encrypted Easy Save 3 (.es3) saves?

Yes. Easy Save 3 encrypts with AES under a password each developer picks, and the passwords of many popular games are public, so we try all of them first. If none fits, the editor asks for the password of your game. The edited save is encrypted again with the same password, so the game loads it as its own.

Why do Unity saves all look different?

Unity has no save format of its own — each developer picks one. The common ones are JSON via JsonUtility, that same JSON wrapped in base64, and .NET binary serialisation (NRBF). All three open here, and detection reads the file contents rather than the extension.

I cannot find a save file at all

Look in the Unity persistent data folder for the game (see above). If the only thing there is a registry-backed PlayerPrefs, there is no file to edit — the game has to write an actual save for the editor to work on.

My Unity save is some other format

Upload it anyway. A recognised-but-unsupported file is logged and retained, which is how formats get prioritised — the ones people upload most get built first.
