To edit a Minecraft server’s settings, stop the server, open server.properties from the server’s working directory in a plain-text editor, change only the value after the correct = sign, save the file, and restart the server. Java and Bedrock use different property sets, and a Java setting can be silently ignored by Bedrock.

What server.properties is and where to find it
server.properties is the text configuration file read by Minecraft server software. Each active setting uses one line in the form key=value. For example, the whitelist setting is written as white-list=true. The text before the equals sign is the key; the text after it is the value.

In a normal installation, that is the folder containing the server files. However, the folder from which the server process is launched matters more than the location of the server JAR itself. If a startup script changes directory first, or if a hosting panel launches the process from another directory, server.properties is created or read there instead.
If you see more than one copy, identify the copy used by the running process rather than editing the one that merely looks familiar. A reliable check is to stop the server, note the directory containing the files it uses, and start it from that same directory. Hosting panels may expose this as the server’s working directory or installation path.

Identify the edition before changing anything
Java Edition and Bedrock Dedicated Server do not share the same configuration keys. A property copied from a Java file into a Bedrock file may be read and silently ignored, according to a GameServerKings reference, without an error or warning. That makes choosing the correct file more important than the edit itself.
Signs that you are editing a Java server
- The server is launched with a Java command such as
java -jar minecraft_server.jar. - The directory contains a Java server JAR and files such as
eula.txtandserver.properties. - The file’s keys match the Java Edition documentation on the community-maintained Minecraft Wiki.
Signs that you are editing Bedrock Dedicated Server
- The server is the separately distributed Bedrock Dedicated Server software rather than a Java JAR.
- The supplied
server.propertiesis heavily commented and uses Bedrock-specific keys. - Java property names pasted into it do not produce the expected behavior, even though the file saves normally.
Do not “translate” a Java key by changing punctuation or capitalization. Use the key set generated for your edition. The Bedrock file’s comments are useful as a reference, so keep an untouched copy before making changes.

Stop the server first
Stopping the server before editing is the safest procedure. A running server can still write configuration data, and a clean shutdown gives it a chance to finish its own file operations. If your panel has a Stop button, use it and wait until the console reports that the process has ended. From a terminal, use the server’s normal shutdown command or close the process only after it has stopped cleanly.
If you cannot stop the server immediately, make a backup copy and schedule the edit for the next restart. Editing while the process is active can leave you unsure whether the final file contains your changes or a later write from the server.

Use a plain-text editor
Open the file with an editor that saves unformatted text. Notepad on Windows, TextEdit in plain-text mode on macOS, Kate on Linux, and terminal editors such as nano or vim are suitable. Avoid word processors and rich-text modes: they can add formatting characters that the server does not understand.
Before editing, copy server.properties to a backup with a date in its name. A backup lets you restore the previous configuration if the server refuses a value or if you lose track of several changes.
Step-by-step: edit a property safely
- Open the server’s active directory. Use the directory from which the server software runs, not an unrelated download or backup folder.
- Stop the server. Confirm that the process has ended before opening the file for editing.
- Make a backup. Duplicate
server.propertiesbefore changing it. - Open the file as plain text. Keep the existing line endings and ordinary text encoding if the editor asks.
- Find the exact key. Use the editor’s search function. Keys are spelling- and punctuation-sensitive; do not rename them.
- Change only the value. Leave the key and equals sign intact. For a Boolean setting, use the form expected by the file, such as
trueorfalse. For a numeric or text value, enter only the value, without explanatory words. - Leave comments alone. A line beginning with
#is a comment and does not affect the game. You can read it for context, but changing a comment does not change a setting. - Save the file. Check that the editor did not append a second extension such as
.txtor convert the file to a rich-text format. - Start the server again. A restart is the dependable way to make configuration changes active.
- Verify in the console or in game. Test the particular behavior you changed instead of assuming that a successful save means the value was accepted.
Do not add spaces, quotes, or a second equals sign unless the existing property format specifically calls for them. The safest edit is a replacement of the value on an existing line.
Restart versus /reload
The Minecraft Wiki states that restarting the server applies changes made to server.properties. It also documents /reload, issued from the console or in game, as a way to reload changes without a full process restart. The exact scope of /reload is not fully established for every property, so use a complete restart when a setting does not respond or when you need predictable behavior.

| Method | How to use it | When it is appropriate | Limitation |
|---|---|---|---|
| Full restart | Stop the server, then start it again | Applying all edited properties; troubleshooting a change that did not take effect | Players lose access while the process is stopped |
/reload |
Run /reload in the console or in game |
Quickly loading supported changes without restarting | The retrieved documentation does not establish that every property is reloaded |
For whitelist edits, NamuWiki reports that the modified list is loaded after /reload; until then, the server continues using the existing whitelist. If the result is not what you expect, stop the server and restart it rather than repeatedly issuing reload commands.
If the file does not exist: initialize default settings
The Minecraft Wiki’s server tutorial documents an initialization option that creates the initial settings files without running the server. If server.properties or eula.txt is missing, run the server JAR with --initSettings from the directory where you want those files created:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
java -jar minecraft_server.jar --initSettingsThe filename in the command must match your server JAR. Running the command from the wrong directory creates the files there, so change to the intended server folder first. The option writes default files; it does not apply a custom configuration for you. After initialization, open the generated server.properties, make the required edits, and start the server normally.
If a hosting panel manages the server, use its file manager or documented startup option instead of adding command-line arguments blindly. The panel may already provide an initialization action and a fixed working directory.

Worked example: enable the Java whitelist
The Java whitelist is controlled by the white-list property. A value of true enables it:
white-list=true- Stop the server and open the active Java
server.properties. - Find the line beginning with
white-list=. Keep the key exactly as written. - Replace only the value with
true, then save. - Run
/reloadif you need to load the changed list without a full restart, or restart the server for the most reliable result. - Confirm that the intended players are on the server’s whitelist using the server’s normal whitelist-management commands, then test a connection.
GameServerKings reports that the default for white-list changed from false to true in version 26.3. That is a version-sensitive, third-party claim rather than a universal rule for every release. Inspect the generated file on your version instead of assuming a default.
Players already online
The same third-party guide describes enforce-whitelist as controlling what happens to players who are already online when the whitelist is reloaded. Because behavior can depend on the server version and reload method, treat that key as a separate decision: changing white-list determines whether the whitelist is enabled, while enforce-whitelist determines the handling of players present during a reload according to that guide.
If a player can still join after an edit, check three things in order: that you changed the active file, that the value is exactly true, and that the server was restarted or reloaded after saving. Then verify that you are testing the Java server whose file you edited, not a Bedrock instance or a second installation.

Java and Bedrock properties are not interchangeable
| Question | Java Edition server | Bedrock Dedicated Server |
|---|---|---|
| Configuration file | server.properties generated and read by the Java server software |
A separate server.properties with a different key set |
| Can Java keys be pasted into it? | Use the Java keys documented for that server | GameServerKings says Java keys may be read but silently ignored, with no warning |
| Reference material | The Java-oriented Minecraft Wiki documentation | The heavily commented file included with the Bedrock Dedicated Server download |
| Best verification | Restart or reload, then test the Java behavior you changed | Use the Bedrock key and test in the Bedrock server process |
There is no safe copy-and-paste conversion between editions. Even when a key looks familiar, its spelling, available values, or effect may differ. Keep separate backups and notes for each server.
Why the server may rewrite your file
On startup, the server can add properties that are missing and supply defaults. A third-party reference also reports that missing or invalid values are replaced and that the file is rewritten. Rewriting can remove comments you added yourself. Treat comments as temporary documentation, not as permanent storage for operating notes.
Keep custom notes in a separate text file or in your administration documentation. After every restart, reopen server.properties if you need to confirm that the server retained a value. If the line has been restored to a default, compare the value with the format expected by your edition and restore from the backup only after correcting the input.
Troubleshooting by symptom
The edit has no effect
- Confirm that the file is in the server’s working directory. A second copy elsewhere is a common source of confusion.
- Check that the key text was not changed and that the value appears after the first equals sign.
- Restart the server. Use
/reloadonly when the property’s reload behavior is known to be adequate. - Make sure the server process you restarted is the same edition and installation whose file you edited.
The file changed back after startup
- Look for a missing or invalid value that the server replaced with a default.
- Check the spelling and capitalization of the key, then compare the value with the format already used in the generated file.
- Use the backup to identify what changed, but do not restore a Java property file over a Bedrock installation or the reverse.
Your comments disappeared
The server’s rewrite behavior can strip comments when it regenerates the file. Store explanations outside server.properties and regard the generated file as machine-maintained configuration.
Whitelist behavior is unexpected
- Verify
white-list=truein the active Java file. - Reload or restart after saving; an unsaved edit is not visible to the running process.
- Check whether the test player was already online and whether your version uses
enforce-whitelistfor reload handling. - Do not apply Java whitelist keys to a Bedrock file.
The file is missing
Run the initialization command from the intended working directory, or start the server normally once so it can create its defaults. If a panel controls the process, use the panel’s file manager and startup settings to identify where it writes configuration.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteA repeatable maintenance routine
- Record the edition, server version, and working directory before changing settings.
- Stop the process and make a dated backup of
server.properties. - Edit one logical group of settings at a time so a later problem has a clear cause.
- Preserve every key exactly and alter only its value.
- Save as plain text, restart, and test the behavior that motivated the change.
- Keep operational notes outside the file because startup rewrites can remove comments.
- When a value is ignored, check edition and file location before experimenting with different syntax.
Following this routine avoids the two most damaging mistakes: editing a file that the server never reads and using a valid-looking key from the other Minecraft edition.
