100% local processing. Your save never leaves your device.
Files are decoded directly in your browser. Zero backend and zero data upload.
Native-speed Oodle & Zlib decompression via custom compiled WebAssembly.
Skips heavy foliage and map grids to parse multi-gigabyte saves under 500MB RAM.
Select or drop the folder containing Level.sav and the Players/ subfolder.
"The Unreal Engine 5 GVAS container format encapsulates world state, player profiles, and character structures in Palworld. Migrating saves between local co-op and dedicated servers requires strict GUID parity and container integrity."
"Unreal Engine saves binary data using the GVAS header ('GVAS') followed by structured properties and serializable custom version tags to ensure backwards and forward asset compatibility."
No. SaveGuard operates 100% in your browser using local WebAssembly and Web Workers. Not a single byte ever leaves your computer or device.
In 4-player co-op, the host player is assigned GUID 00000000000000000000000000000001. Dedicated servers do not recognize this ID, forcing the host to start fresh unless GUID migration is applied.
On dedicated servers, WorldOption.sav completely overrides PalWorldSettings.ini, preventing custom XP multipliers and death penalty rules from taking effect.
Stop the recurring red autosave failure modal caused by DynamicItemSaveData actor bloat and disk write timeouts.
Unpack Windows Gaming Services (WGS) hex blobs into standard Level.sav and migrate Pals, bases, and technology to Steam.
When transferring local co-op saves to a dedicated server, the host loses their character because co-op hardcodes the host to 0000...0001.
If the server crashes whenever players access the Palbox, a guild's registered admin_player_uid is missing from Players/ (headless guild).
Fix the GameUserSettings.ini DedicatedServerName hash mismatch that causes dedicated servers to generate empty maps.
Repair truncated save_game_class_name ("None") headers after unclean Docker or Linux server shutdowns.
Locate Proton compatdata backup snapshots and recover Palworld saves overwritten by Steam Cloud conflicts.
If custom server settings (XP rates, egg timers, death penalties) are ignored on your server, WorldOption.sav is overriding them.
Fix "World data failed to load" errors after unexpected crashes by verifying GVAS truncation and restoring rolling backup snapshots.
Exact filesystem paths for Steam Windows PC, Xbox Game Pass PC, Windows Dedicated Server, and Linux/Docker servers.

Common questions regarding Palworld save safety, co-op host migration, and local diagnostics.
No. SaveGuard operates 100% locally inside your web browser using WebAssembly (oozextract) and Web Workers. Your save files are never transferred over the network or stored on any server.
Simply drag and drop your Palworld world save folder into the scanner above. SaveGuard will inspect Level.sav headers, verify Oodle compression integrity, scan for the 0000...0001 co-op host slot, and audit guild parity in seconds.
In 4-player listen co-op, Palworld hardcodes the hosting player's GUID to 00000000000000000000000000000001. Dedicated servers do not recognize this dummy ID because they authenticate players through their authentic Steam or Xbox network credentials, forcing the host to start fresh at Level 1.
On dedicated servers, WorldOption.sav overrides settings in PalWorldSettings.ini, preventing custom XP multipliers and death penalty rules from taking effect. Deleting or renaming WorldOption.sav restores full control to your INI file.
Do not delete your world. Palworld automatically maintains timestamped backup snapshots in Pal/Saved/SaveGames/<SteamID>/<WorldGUID>/backup/. You can test your save integrity with SaveGuard, then restore the newest healthy snapshot from the backup folder.
