Why and for Who?

While moving from an Android device to an iOS one, I encountered this stupid issue using MoveToIOS (as the process is not annoying and error prone as is) — among other things, WhatsApp Stickers do not transfer in the move to the new phone for some reason!

On Android at least it is possible to access them via:

Internal Storage/Android/media/com.whatsapp/WhatsApp/Media/WhatsApp Stickers/

Now hear me out, I'm a bit of sticker hoarder, and even after filtering and copying them out I was still left with 300+ stickers, not in packs nor organized of course.

So I started researching a way to just dump and install them on my new phone, and I came to the sad conclusion that there is no real way to batch up the process — and the sadder conclusion — I am the only human with that much stickers that reached this issue.

So I decided to streamline this as much as I can.

Basically just grab the WhatsApp Stickers folder from the app's files and run this tool on them to create packs out of all your stickers, send them to yourself and open them with a third-party WhatsApp Sticker app to install.

Why a helper app is required (iOS) & Dead End Research

I wanted to streamline this completely and have no dependency on third-parties — upon my research a way that looked promising and was commonly talked about was leveraging the Pasteboard + whatsapp://stickerPack

• via file
• via url

There were conflicting views all over and no one place with an answer — so TLDR — there is no way to do this.

WhatsApp iOS only accepts sticker packs through a native Sticker Provider extension — an App Store app that registers with WhatsApp via Apple's framework. There is no supported web-based, file-based, or URL-scheme installation path.

The old whatsapp://stickerPack pasteboard API (2018) required a custom UTI type (net.whatsapp.third-party.sticker-pack) and binary NSJSONSerialization data — neither of which can be produced from a browser or file.

Even on its last working versions, the URL scheme was fragile and frequently broken by iOS updates, WhatsApp Business conflicts, and Apple's clipboard security model (blocked on file:// URLs entirely). Modern WhatsApp versions have removed support for it altogether.

Hopefully this serves someone.
