Borderlands 4 Save Editor - Free Online Save Game Editor for PC

This is a free online save editor for Borderlands 4 on PC (Steam and Epic Games). It's a web-based tool that runs entirely in your browser - no download or installation required. The save editor decrypts your encrypted .sav files into human-readable YAML format, allows you to edit the YAML manually or apply preset modifications, then re-encrypts the file so Borderlands 4 can read it. You need to provide your Steam ID (17 characters) or Epic ID (32 characters) for the encryption/decryption to work properly.

The save editor includes extensive presets: Remove map fog, discover all locations, unlock all safehouses, unlock all collectibles (ECHO logs, capsules), complete all challenges, complete all achievements, skip story missions, skip all missions, change character class, max level (50), max SDU, unlock all vault powers, unlock all hover drives, unlock all specializations, unlock UVHM mode, set items to character level, grant max money & Eridium, unlock new game shortcuts (profile.sav), and unlock all cosmetics (profile.sav). These presets apply tested, reliable modifications instantly.

Yes! This Borderlands 4 online save editor works with both character saves (1.sav, 2.sav, etc.) and profile.sav. The profile.sav file contains global data like cosmetics, bank contents, and Black Market inventory. Use the 'Unlock all cosmetics' preset on profile.sav to unlock every skin, head, and weapon skin for all characters. The 'Unlock new game shortcuts' preset lets you start new characters at level 30 with story complete.

On Windows, navigate to %USERPROFILE%\Documents\My Games\Borderlands 4\Saved\SaveGames\. For Steam, you'll see a folder with a 17-digit name (your Steam ID). Navigate to .\<steam_id>\Profiles\client\ to find your saves. Files named 1.sav, 2.sav, etc. are character saves. The profile.sav file contains global data. For Epic Games, the folder structure is similar but uses a 32-character Epic ID instead.

For Steam ID (17 characters): Visit https://store.steampowered.com/account/ or look in your save file path. For Epic ID (32 characters): Visit https://www.epicgames.com/account/personal/. You must enter the correct ID for your platform (Steam or Epic) or the Borderlands 4 save editor won't be able to decrypt and re-encrypt your save files properly.

Using a save editor for Borderlands 4 is generally safe. This tool only modifies local save files on your PC - it doesn't hack the game process, modify game files, or interact with online servers. It's functionally the same as using the classic Gibbed save editor for Borderlands 2 and Borderlands 3, which millions of players used without ban issues. However, Gearbox's policies can change, so use at your own discretion. We recommend keeping backup saves.

While Gibbed's save editors were legendary for Borderlands 2 and 3, this Borderlands 4 online save editor offers a modern alternative. It works entirely in your web browser (no desktop program to download), has a clean interface with one-click preset buttons, supports both Steam and Epic platforms, handles the new BL4 save encryption automatically, and includes advanced presets like UVHM unlock, specialization completion, and achievement triggers. It's essentially a more accessible, user-friendly evolution of the traditional desktop save editor.

You can do both! The Borderlands 4 save game editor includes an integrated YAML editor where you can manually modify any value in your save file. This gives you complete control for advanced edits. However, for common modifications, the preset buttons are faster and safer since they apply tested changes consistently. Presets update the YAML text in the editor immediately, so you can see exactly what changed.

Always export your original save as a backup before making any edits! After clicking Import in the save editor, immediately click 'Export as .sav' to save a timestamped backup copy. Keep these backup files in case something goes wrong. The save editor encourages this best practice. Also consider disabling cloud saves for Borderlands 4 to prevent your edited saves from being overwritten by cloud backups.

Yes, but with caution. You can safely replace save files while the game is running as long as a different character is selected. If you try to modify a save for the currently loaded character, it won't work because the save is in memory and will overwrite your changes when the game saves. Never attempt to modify profile.sav while the game is running for the same reason.

The save editor includes basic item manipulation through the 'Set all items to character level' preset, which updates all inventory items to match your character's level. However, advanced item editing (creating custom weapons with specific parts/stats) is not planned. For that level of item editing, you would need to manually edit the YAML, which requires understanding the BL4 item serial format.

Yes, this save editor is completely free and open source! There's no cost, no subscription, no premium features behind a paywall. It's a community tool built to help Borderlands 4 PC players customize their saves easily. The source code is available on GitHub, and contributions are welcome from the community.
