어떤 게임 세이브든, 바로 여기서 편집하세요.

A save editor lets you open a game's save file, read and modify its stored data — such as health, gold, level, items, flags, and coordinates — then export a valid save file your game can load. Online Save Edit performs every operation client-side in your browser: no software to install, and your save file is never uploaded to any server.

Yes. Every operation runs entirely in your browser using JavaScript. Your save file never leaves your device — it is not uploaded, logged, or stored anywhere. We have no server-side file processing. You can verify this yourself by opening your browser's Network tab: no outbound file transfer occurs when you load or process a save.

Go to the homepage and drag and drop your save file onto the upload zone (or click to browse your files). The tool auto-detects the game format and displays editable fields. Change the values you want — health, gold, items, flags, etc. — then click "Download Save" to get the modified file. Replace the original save in your game's save folder and launch the game to see your changes.

Drop your save file onto the editor — it detects the format automatically (Cookie Clicker, Terraria, Borderlands, RPG Maker, Unity, Ren'Py, No Man's Sky, and more). Edit the fields shown. Click "Download Save" to export the modified file. Back up your original save first, then replace it in your game's save directory.

In most jurisdictions, modifying save files for personal single-player use is legal and widely accepted by the gaming community. It may violate a game's Terms of Service if used in online or multiplayer modes, which could result in a ban. We recommend using any save editor only in offline, single-player contexts and always reviewing the game's ToS before modifying saves for online play.

After making your edits, click the "Download Save" button to download the modified file to your computer. There is no account or session to log out of — simply close the browser tab when you are done. Copy the downloaded file back to your game's save folder (overwriting the original, or rename the original as a backup first), then launch your game normally.
