steal LINE stickers to telegram

1. pull all LINE stickers from you phone

adb pull /storage/sdcard0/Android/data/jp.naver.line.android/stickers/ .

2. find your purchased sticker pack (you can look at the "preview" file)

for example, the sticker pack of Puella Magi Madoka Magica is # 1101

Note, you also can find stickers sent by your friend.

3. convert your the files (from PNG) to the WebP format

I'm too lazy so I wrote a script to do the following stuffs:

mkdir madoka
cp ../stickers/1101/* madoka/
cd chocola/
rm *_key preview thumbnail *.tmp
for i in *; do cwebp $i -o $i.webp ; done
for i in `ls | grep -v webp`; do mv $i $i.png; done
cd ..

4. put them in your phone, done!



Test:

The first one is the file in PNG, the second one is in WebP.
