There are a lot of apps and programs out there that can help you download multiple numbers at once, but not all of them are compatible with your phone. Some don't work on Android, while others require you to pay a fee to download more numbers. And even if you get them, they will have a limit on how many numbers you can download at once.

Developers have created this tool to simplify downloading and saving multiple phone numbers from WhatsApp at once. The tool is not official and has no any official relationship with WhatsApp. If it is not working, please disable other WhatsApp extensions and try, then it is working.
