Palworld Save Editor — Online, No Download
PalTweak is a browser-based Palworld save editor. Open the site, upload your Level.sav, edit your Pals and your character, then download the file back — no .exe, no Python, no Docker, nothing to install.
Edit your save in the browser — nothing to install
Most Palworld save editors are desktop programs: you download an .exe, or set up Python or Docker, before you can change a single value. Many are unsigned, so antivirus software flags them as a false positive and scares people off.
PalTweak runs entirely in your browser. There is nothing to download, install or scan — you open the page, upload a copy of your Level.sav, make your edits and download the result.
Works on Windows, macOS, Linux and Chromebook
Because it runs online, PalTweak works the same on every operating system. If you play on a Mac, a Steam Deck browser or a Chromebook — where the desktop editors simply don't run — you can still edit your save.
What you can edit
PalTweak edits the values stored in your world's Level.sav:
- Pal level — free
- Add and clone Pals into a player's box — free
- IVs, souls and star rank
- Passive skills and active moves
- Heal, feed and cure sickness — free
- Species, gender and the lucky / alpha flags
- Your player character — level, status points, HP, condition and name
Free to start, one-time upgrade for the rest
Setting a Pal's level and adding or cloning Pals are free. The remaining values — IVs, passives, moves, souls, species and the full player editor — are covered by a one-time €4.99 Pro unlock. There is no subscription.
Your save stays private
Uploading a save is a matter of trust, so PalTweak holds onto it as briefly as possible. Your file is sent over an encrypted (HTTPS) connection, kept only in a temporary in-memory session while you edit, never written to disk, never shared, and discarded when your session ends. The only download goes back to you.
Built for the Palworld 1.0 save format
Palworld's save format changes with major updates, and that is where older editors break. PalTweak is built and tested against the current 1.0 format, so an edited Level.sav loads back into the game cleanly. When a patch changes the format, the parser is updated to match.
