How It Works

Make a backup, edit only the values you understand, then verify the new file in game.

1

Choose Save

Select an MV .rpgsave or MZ .rmmzsave file from your local game folder.

2

Edit Values

Start with tested gold edits; treat other detected fields as candidates until verified in game.

3

Download

Download the rebuilt file and keep your original backup until tested.

Private by default

The main editor reads and rebuilds files in your browser. Files selected on the home page are handed to the editor through browser storage, not a server endpoint.

RPG Maker focused

Choose the MZ .rmmzsave or MV .rpgsave editor. MV gold editing is verified in an official trial project.

Backup-first editing

The workflow is designed for small, reversible changes rather than broad unsupported engine claims.

Browser-Based RPG Maker Save Editor

Welcome to SaveFileTool, a free RPG Maker MZ save editor for compatible .rmmzsave files, with backup-first guidance before you replace any file.

For MV saves, open the RPG Maker MV save editor and choose a .rpgsave file. Gold editing has been verified in an official MV trial project.

Frequently Asked Questions

Is this online save editor safe to use?
MV .rpgsave and MZ .rmmzsave files are processed locally in your browser. Always keep a backup before replacing a save file.

What games are supported?
Separate editors accept MZ .rmmzsave and MV .rpgsave files. MV gold editing was verified in an official trial project; custom game plugins may differ.

Do I need to install any software?
No. This is a web-based tool for local MV .rpgsave and MZ .rmmzsave files.

Where are my save files located?
MZ games commonly use save/. Desktop MV games may use www/save/ or save/. Browser games may store saves in browser storage.

Will editing my save file corrupt my game?
Any save edit can break progress if the wrong field is changed. Back up the original file first.

Can I edit Steam or console game saves?
Desktop MV .rpgsave and MZ .rmmzsave files may work when the raw save file is available. Console saves are usually encrypted or containerized and are not supported.

How do I modify gold or money?
Choose .rpgsave in the MV editor or .rmmzsave in MZ, change gold carefully, then download and test the edited file in game.

Can I unlock all items or achievements?
Inventory and flags vary by game. Edit small values first and verify in game.

What file formats are supported?
Public entries cover MZ .rmmzsave and MV .rpgsave. MV gold editing was verified in an official trial project. Older RPG Maker formats remain outside public support.

Why can't I open my save file?
It may not be an RPG Maker save, may be encrypted, or may use a custom structure.

Is this free? Are there any limits?
SaveFileTool is free to use with an enforced 10MB per-file limit.

Can I edit online game saves?
No. Online game progress is usually stored on servers, not in local RPG Maker save files.
