Frequently Asked Questions

What does a save editor do?

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.

Is onlinesaveedit.com safe?

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.

How do I edit my save file?

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.

How to use the save editor?

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.

Is it legal to modify game files?

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.

How to save and exit the save editor?

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.

About Our Free Online Save Editor

Online Save Edit is the free, privacy-first online save editor that lets you modify game save files directly in your browser — no downloads, no account, and no file uploads to any server. Whether you need a Cookie Clicker save editor, a Terraria save editor, an RPG save editor, or a general-purpose save editor online, our tool automatically detects the file format and opens the right editor in seconds.

What Is an Online Save Editor?

An online save editor is a browser-based tool that lets you open, modify, and re-save game save files without installing any software. Traditional save editors require a desktop application that you must trust with your save data. Our save editor online runs entirely in your browser using JavaScript — your save file is never transmitted to any server, making it the most private and secure option available for PC gamers, modders, and anyone who wants to explore their game's save structure.

How the Save Editor Online Works

Drop a save file into the editor and it reads the file header, extension, and content patterns to identify the game engine automatically. It then decodes the save into readable, editable fields — health, gold, level, inventory, flags, coordinates, and more. Make your changes in the browser, click Download Save, and the tool re-encodes the file to the exact original format, ready to copy back into your game folder. No extra tools, no command line, no setup required.

Supported Games & Formats

Our online save editor covers a wide range of titles and engines. The Cookie Clicker save editor decodes the Base64-encoded format to edit cookies, buildings, and prestige. The Terraria save editor parses XOR-encrypted .plr and .wld files for character and world edits. The Borderlands save editor, Borderlands 2 save editor, and Borderlands 4 save editor handle character stats and inventory across the franchise. The Ren'Py save editor works with persistent saves from visual novels. The NMS save editor (No Man's Sky) lets you modify galaxy coordinates, inventory, and units. The Satisfactory save editor, RPG Maker save editor (MV/MZ), Unity PlayerPrefs, INI files, and plain JSON round out the collection — all auto-detected on drop.

100% Private — Your Files Never Leave Your Device

Unlike many save editors that require uploading files to a remote server, every operation in our online save editor runs locally in your browser. We have no server-side file processing, no database, and no ability to see your save data. Your files stay entirely on your machine. This matters particularly when editing saves for games with active anti-cheat systems, or when saves contain personal data. Always back up your original save file before making any edits — we make that easy with the built-in backup download.
