Antimatter Dimensions save guide
Antimatter Dimensions browser save location and backup steps
The Eovant browser build stores its save in this site's browser storage under the localStorage key dimensionSave. The safest portable backup is the game's own Export save or Export save as file option.
Direct answer
Where is the Antimatter Dimensions browser save?
On Eovant, Antimatter Dimensions stores progress in browser localStorage for eovant.com using the key dimensionSave. It is not an ordinary save file in Downloads or a Windows AppData folder. For a backup you can move between browsers or devices, use the game's own Export save or Export save as file command instead of copying browser internals.
Browser storage, text export, and file export compared
| Save method | Where it is | Portable? | Best use |
|---|---|---|---|
| Automatic browser save | eovant.com localStorage key dimensionSave | No, not by itself | Continuing in the same browser profile |
| Export save | Clipboard as an encoded text string | Yes | Quick copy into a private note or password-safe document |
| Export save as file | A dated .txt file in the browser download location | Yes | A named backup before clearing data or changing devices |
| Automatic backup slots | Browser storage for the current save slot | Not until exported | Recovering from a recent in-game mistake in the same browser |
How to export an Antimatter Dimensions save
- 1
Open Options
Load your current game, open Options, and go to the Saving section.
- 2
Check the active slot
The export functions use the current save slot. Select the slot whose progress you intend to protect.
- 3
Choose a backup format
Use Export save to copy the encoded save string to the clipboard, or Export save as file to download a dated text file.
- 4
Store the backup away from browser data
Move the file or pasted string somewhere that will survive a browser reset, profile deletion, or device failure.
- 5
Keep more than one dated copy
A newer export can contain a mistake you later notice. Keeping a small rotation makes recovery safer.
How to import the save on another browser
- 1
Open the destination build
Load Antimatter Dimensions on the destination browser and wait for the game interface to appear.
- 2
Open Options and Saving
Use Import save for an encoded string or Import save from file for the exported text file.
- 3
Select the intended slot first
Import applies to the active game state, so confirm the destination slot before proceeding.
- 4
Paste or choose the file
Use the complete unedited string, or select the .txt file created by Export save as file.
- 5
Verify progress immediately
Check your antimatter, unlocked tabs, achievements, and save name before closing the original browser.
Why a Windows save-location answer can be wrong here
Antimatter Dimensions also exists outside this browser page, so search results may point to Steam userdata, AppData, or another desktop folder. Those locations describe a different platform. The Eovant edition is a web build, and its checked production code loads dimensionSave from the browser's localStorage for the current site.
Browser developer tools can display that storage, but editing the encoded value by hand is unnecessary and risky. The built-in export validates the normal save flow and gives you a copy designed for the matching import command.
Safe save-transfer checklist
- Export the active slot before changing browsers or devices
- Keep the encoded string private because it contains your game progress
- Do not edit the text file or remove characters from the copied string
- Import into the intended slot and verify the result before deleting the old copy
- Keep at least one older dated backup in case the newest save is unwanted
Antimatter Dimensions save questions
What is the browser save key?
The checked Eovant production build uses the localStorage key dimensionSave.
Where does Export save put the backup?
Export save copies an encoded string to the clipboard. Export save as file downloads the current slot as a dated .txt file.
Can I transfer progress to another browser?
Yes. Export the current save as text or a file, open the game in the other browser, select the intended slot, and use the matching import command.
Will clearing cookies delete my progress?
Clearing site data can remove browser-stored progress. The exact browser dialog varies, so make an exported backup before clearing any eovant.com data.
Should I use a save editor?
A save editor is not needed for backup or transfer. Use the built-in export and import functions to avoid corrupting the encoded data.
Back up the current slot
Open the local browser build, check the active slot, and create a dated export before changing site data or devices.
