Palworld Corrupted Save Checker
Palworld save won't load, or you're afraid it's gone? Point this page at your
SaveGames folder (or a zip). It checks every world and every rolling backup
for a truncated or unreadable Level.sav, tells you whether
the damage is real - and if it is, finds the most recent intact backup and
hands it back as a server-ready zip.
Nothing is uploaded and your original is never touched. The check reads only file names, sizes, and structure (a zip is read via its central directory - nothing decompressed). A recovered backup is repackaged locally in your browser from your own files. Verify with the network tab open.
Check your save for corruption
Pick your world folder, its parent, or the whole SaveGames tree - the checker
finds every world and backup inside. Close Palworld fully first, so nothing is mid-write.
Reads names & sizes only.
Only the zip's index is read - never decompressed.
All checks run locally in this tab. Your save is never uploaded.

What "corrupted" usually means in Palworld
A save that "won't load" is rarely random - it's almost always one of a few structural failures this checker can see without parsing a single byte of game data:
| Signature | What happened | Recovery |
|---|---|---|
Truncated Level.sav |
The file is a few bytes, or far smaller than a real world - usually a crash or a copy taken while the game was still writing. | Restore the most recent intact backup (this tool finds it). |
Missing Level.sav |
The world itself isn't in the folder - only players or metadata came across. | Recover from a backup, or re-copy the full world with the game closed. |
| Newer backup is smaller | The game auto-saved once after the corruption, so your newest backup is the bad one. | The tool ranks by size + timestamp and points at the older, intact backup. |
| Not actually corrupted | Wrong folder picked, or a Game Pass / co-op layout the server can't read as-is. | The tool says the save is fine and routes you to the right migration step. |
Need the full diagnose-and-migrate flow instead of just corruption? The Save Rescue tool runs the same engine and also handles host rebinds and Game Pass conversion; deeper byte-level repair stays with PalworldSaveTools (MIT).
How backup recovery works here
When Palworld saves, it rotates a set of backups with cryptic timestamped folder names,
each holding its own Level.sav. The recovery data is usually already on disk -
the hard part is knowing which backup is the right one. This tool reads every backup,
resolves each timestamp, checks each Level.sav for truncation, lays them out
newest-first, and picks the most recent intact one. Click download
and it repackages that backup - Level.sav at the zip root - ready to drop onto
your server, then re-checks the result and confirms it reads intact before you trust it.
Manual recovery (no JavaScript needed)
- Close Palworld / stop the server so nothing is writing to the save.
- Open your world folder and look at
Level.sav- if it's 0 bytes or only a few KB, it's truncated. - Open the world's
backup/folder. Each timestamped subfolder holds a full save. - Find the newest subfolder whose
Level.savis a normal size (not smaller than the others). - Copy that backup's contents over your world folder's contents, keeping the folder name the server expects.
- Keep the damaged copy aside until the restored world loads and looks right.
FAQ
Is my save really not uploaded?
Really - there's no upload endpoint on this page. The check is client-side JavaScript over names and sizes, a zip is read by slicing only its central directory, and a recovered backup is zipped locally from your own files. The network tab shows zero requests carrying your save.
The checker says my save is fine - why won't it load then?
If the structure is intact, the problem is usually elsewhere: a version mismatch (the server
is older than the save), the wrong world folder on the server, or a
WorldOption.sav / settings issue. The report calls out what it can see and
links you to the right next step.
Can it recover a save with no working backup?
No tool can rebuild data that isn't there. If both the active Level.sav and
every backup are truncated, the checker says so honestly rather than handing you a broken
file - restore from your own external backup if you have one.
