Which save file formats does Save Editor support?

Save Editor Online accepts a broad range of save files, including common extensions like .save, .sav, .rmmzsave, .rpgsave, .sqlite, .sol, .gz, .es3, and .dat, plus many engine-specific, compressed, serialized, JSON, and text-based formats. You don't need to know your file's format in advance — the tool detects it automatically after upload and opens the best editor for it. The main condition is that your file must be a save file the tool can recognize; if it isn't, you'll get an error instead of an editor.

Supported formats at a glance

Beyond these named extensions, the site states it handles a large library of additional engine-specific, compressed, serialized, JSON, and text-based save formats. It also lists support for RPG Maker, Ren'Py, Unity, Unreal Engine 4/5, Godot, and HTML games.

How format detection works

1. Upload your file — click Upload file and choose the save you want to edit.
2. Automatic detection — the tool detects the format and opens the best available editor.
3. Edit values — change things like gold, items, stats, variables, or text.
4. Download — click Download to save the updated file.

Because detection is automatic, you don't have to match your file to a specific editor yourself. If a format is supported, the right editor opens; if it isn't, you'll see an error.

Upload file vs. Paste code

The site offers two input methods, and choosing the right one matters:

• Upload file — use this for raw binary or garbled data. If your data looks like unreadable text (for example, sequences of odd symbols), upload the file instead of pasting.
• Paste code — only for data that can be safely pasted as normal text, such as Base64 or save codes. Pasted text is uploaded as savegame.txt.

If you try to paste binary-looking data, the tool may reject it or fail to parse it correctly, so match the method to your data type.

Practical notes before you edit

• Back up your save first. The site explicitly advises keeping a backup before making changes.
• Watch the file size limit. There's a maximum upload size, and oversized files trigger a "File is too large" error.
• Move files to a trusted local folder (like Downloads or Documents) if the browser can't read the file from its current location.
• Retry on temporary errors. Some failures are caused by brief site updates, which the site says usually take less than a minute.

If your save uses one of the listed extensions or comes from a supported engine, it's very likely to work. For anything unusual, upload the file and let automatic detection decide — that's the fastest way to confirm support.
