Overview

• On iOS and Android, go to Settings → Storage and data → Manage storage to see which chats and media occupy the most space and delete items individually or with Select all.
• Guides highlight that videos over about 5 MB or longer than roughly three minutes, duplicate photos, long voice messages, and shared documents are the most common storage hogs.
• Specialists say periodically clearing WhatsApp’s cache improves performance and can help updates install properly, and the app may alert users when storage is running low.
• Files removed in Manage storage are erased permanently, so selections should be reviewed carefully, and some deleted media may still persist in the device’s internal folders—especially on Android—until removed with a file manager.
• To prevent future bloat, outlets recommend disabling automatic media downloads and considering temporary messages so older content clears on a schedule.
