Tips

How to find IDs

See the URL of a sticker item page.

IDs are consecutive

• Official stickers are from 1
• Creator's stickers are from 1000000

Download multiple sticker packages

Use CLI with a loop command.

• Bash

for ((i=1000; i<=1050; i++)); do php download.php $i; done

• PowerShell

for ($i = 1000; $i -lt 1050; $i++) { php download.php $i }

Multiprocessing downloading

Xargs may help.

seq 1000 2000 | xargs -L 1 -P 8 php download.php

In the case of PowerShell 7.0 or newer, ForEach-Object -Parallel is suitable.

2000..3000 | ForEach-Object -ThrottleLimit 8 -Parallel { php download.php $_ }

Notes

• The size of a download page (CGI) would be large because the PHP program outputs a lot of dummy data so that a server sends document data continuously and a browser refresh the screen.
• Sticker resources are located in public web directories, so anyone can get them easily and legally (private use only).
• A few packages contain broken PNGs in iPhone stickers, missing important metadata. These stickers can't open with most applications, but there is a solution. Open them with macOS's application (Preview etc.) and export as new images. Exported images may be valid forms.
