Save editor
How it works
From save file to full pockets in three steps — no installs, no uploads.
-
Locate your save file
Deltarune stores saves in a hidden folder that depends on your OS. Our save file location guide shows the exact path for Windows, Mac, and Linux.
-
Edit in your browser
Open the file with the editor above and change money, items, HP, party members, or story flags. Everything is parsed locally, so edits are instant and private.
-
Download and replace
Download the edited file, put it back where the original was, and start the game. The full walkthrough covers backups and troubleshooting.
Always keep a backup copy of your original save file before replacing it — one spare copy turns any mistake into a non-issue.
What you can edit
Everything the save file stores, exposed as plain fields — no hex editor required.
Money (KROMER)
Set your money to any amount — max out before a shop run, or roleplay a permanently broke run.
HP & stats
Raise max HP, attack, defense, and magic for Kris, Susie, Ralsei, and any other party member.
Items & equipment
Add weapons, armor, and consumables to your inventory or storage box — including boss rewards you missed.
Party & spells
Edit party members and their spells, and build the exact team you want for any fight.
Story flags & plot
Flip the flags the game uses to remember your choices — revisit routes, side quests, and secrets.
Play time
Adjust the play timer stored in your save — handy after restoring a backup or reclaiming a lost file.
Chapter support
Chapter is detected automatically when your save loads. These guides cover what is worth editing in each one.
Chapter 1
Jevil and the Card Kingdom — revisit the original secret boss with a maxed-out inventory.
Chapter 2
Spamton NEO and the Cyber World — grab both the Dealmaker and the Puppet Scarf.
Chapter 3
Tenna's TV World, released June 2025 — fully supported from day one.
Chapter 4
The Dark Sanctuary, released June 2025 — edit the newest saves without waiting.
Why this editor?
Most Deltarune save editors were built for Chapter 1 and quietly abandoned. This one was rebuilt for the full release: it detects your chapter automatically when the file loads, so Chapter 3 and Chapter 4 saves just work — no manual mode switching, and no picking the wrong version and scrambling your file.
It also goes deeper than the classics. The inventory editor covers your storage box as well as your pockets, and a raw flag browser lets power users flip any story flag directly — handy for revisiting choices like the Snowgrave route. The whole tool is mobile-friendly, so you can edit a save on your phone, and it can repair truncated save files that older editors refuse to open.
Your save never leaves your device
The editor is pure client-side JavaScript. When you open a save file, your browser reads it with the FileReader API, and every edit happens in memory on your own machine. The file is never uploaded, logged, or sent anywhere — open your browser's network tools while you edit and see for yourself. Once the page has loaded, it even works offline.
0 bytes of save data uploaded. Ever.
Frequently asked questions
Is this Deltarune save editor safe? Will it steal my save file?
Yes, it is safe. The editor runs 100% in your browser: your save file is read with the FileReader API and never uploaded to any server, so there is nothing to steal. You can even disconnect from the internet after the page loads and keep editing.
Which chapters and platforms are supported?
The editor supports Deltarune Chapters 1, 2, 3, and 4 from the full release on PC, Mac, and Linux. Console versions (Nintendo Switch, PlayStation, Xbox) are not supported, because consoles do not give you access to the raw save files.
Where is my Deltarune save file located?
The save folder depends on your operating system, and on Windows it is hidden inside AppData. Our save file location guide shows the exact path for Windows, Mac, and Linux, step by step.
Does it work with demo saves?
No. The editor supports the full Chapter 1-4 release only. Saves from the free Chapter 1 & 2 demo use a different file format and are not compatible.
Will editing corrupt my save file?
Not if you follow one rule: always back up your original file first. The editor validates your save before writing and can even repair truncated files, but a spare copy costs nothing. Our how to use guide walks you through the backup steps.
Does it work with Chapter 3 and Chapter 4?
Yes. The editor auto-detects your chapter when the file loads and fully supports Chapter 3 and Chapter 4 saves from the June 2025 release, including the new items, equipment, and story flags those chapters add.
Can I get both the Dealmaker and the Puppet Scarf?
Yes. Defeat Spamton NEO once, then use the item editor to add the reward you missed: the Puppet Scarf if you won by fighting, or the Dealmaker if you won by snapping his wires.
