# Adjusting security levels in Tor Browser to balance privacy and usability

Desktop
Android

### Security Levels

Increasing the Security Level in the Tor Browser Security settings will disable or partially disable certain browser features to protect against possible attacks. This in turn might stop some web pages from functioning properly, so you should weigh your security needs against the degree of usability you require. You can undo the changes at any time by adjusting your Security Level and restarting the browser.

###### Standard

- At this level, all Tor Browser and website features are enabled.
- Tor Browser, by default, is set to the "Standard" Security Level.

###### Safer

- This level disables website features that are often dangerous. This may cause some sites to lose functionality.
- JavaScript is disabled on all non-HTTPS sites.
- Some fonts and math symbols are disabled.
- Audio and Video (HTML5 media) are click-to-play.

###### Safest

- This level only allows website features required for static sites and basic services. These changes affect images, media, and scripts.
- Javascript is disabled by default on all sites.
- Some fonts, icons, math symbols, and images are disabled.
- Audio and Video (HTML5 media) are click-to-play.

### Changing the security level

Security levels disable certain web features that can be used to compromise your security and anonymity. Tor Browser for Android provides the same three security levels that are available on Tor Browser for Desktop. You can modify the security level by following given steps:

- Tap on the "kebab menu" i.e. the 3 vertical dots in navigation bar.
- Scroll down to the "Privacy and security" section and tap on "Security Level".
- Tor Browser for Android, by default, is set to the "Standard" Security Level.
- You can now select a Security Level i.e. Standard, Safer or Safest.
- Tap on "Save and restart" prompting the browser to restart.
