Why does steam client webhelper memory usage get high?

I noticed steam client webhelper memory usage is very high on my PC. What causes this and how can I reduce it? Is it safe to disable it?

High memory usage from Steam Client WebHelper usually happens because it handles the web-based parts of the Steam interface, such as the store, library pages, and community tabs. Multiple tabs, background processes, or cached data can cause several WebHelper instances to run, increasing RAM usage. Closing extra Steam windows, disabling hardware acceleration, clearing the Steam cache, or restarting the client can help reduce the memory load.

High memory usage from Steam Client WebHelper happens because the Steam client (by Valve Corporation) uses it like a mini web browser to run the store, library, chat, and overlays. Each of these runs as a separate process, so RAM usage can add up—especially with animated pages, multiple tabs, or cached data. Bugs or outdated versions can also cause memory spikes, which is why restarting Steam or clearing its cache often helps.
