RPG Maker MV & MZ Save Editor
RPG Maker MV and MZ saves are JSON compressed with LZString — not encrypted. Drop your file to read it, edit any value, and download a save the game loads normally.
Intended for your own single-player save files. Editing saves in multiplayer or online games breaks their terms of service and can get your account banned. Always keep a backup of the original file before you change anything.
RPG Maker MV and MZ saves are JSON compressed with LZString — not encrypted, so no key is needed. The file is decoded, pretty-printed for editing, then re-compressed the same way, which produces a file the game loads normally. Gold usually lives at party._gold; the buttons above jump straight to the values people most often change.
How to use
- 1Drop file1.rpgsave (MV) or file1.rmmzsave (MZ) from your game's save folder.
- 2Use the shortcut buttons to jump to gold, steps or playtime.
- 3Edit any value in the JSON below.
- 4Click Rebuild save file and download the result.
Frequently Asked Questions
Do I need an encryption key?
No. RPG Maker saves are not encrypted — they are JSON run through LZString compression, which uses no key at all. The file by itself is enough to read and rewrite it.
Where do I find my save file?
For a downloaded game, look in the www/save folder (MV) or the save folder (MZ) next to the executable, for files named file1.rpgsave or file1.rmmzsave. Browser-played games keep saves in localStorage instead.
Where is gold stored?
Usually at party._gold. The shortcut buttons above find it for you and jump straight to it. Items sit under party._items keyed by item ID, and switches and variables live under the switches and variables objects.
Will the game still load my edited save?
Yes, provided the JSON stays valid. The file is re-compressed with the same LZString variant it came from, so the game sees exactly the format it expects. Keep a backup of the original anyway.
My save is plain JSON, not compressed. Does that work?
Yes. Some MZ projects and browser builds store readable JSON, and that is detected automatically — the rebuilt file is then written back as plain JSON too.
What about the older RPG Maker engines?
XP, VX and VX Ace use Ruby Marshal instead (.rxdata, .rvdata, .rvdata2). Use the Ruby Marshal Viewer for those.
