StampNyaa is a simple cross-platform desktop app for downloading and using LINE stickers in Discord, Whatsapp, Telegram, and anywhere else you can paste images.

Click here to go to the releases page and download the appropriate installer for your operating system in "Assets" (MacOS users should download darwin).

• Use the hotkey Ctrl/Command+Shift+A by default to open the app at any time, or click the icon in your system tray. You can change this hotkey from the settings menu at any time.
• Find your favorite sticker packs on the LINE Sticker Shop.
• Download LINE sticker packs for use with StampNyaa by pressing the + icon in the sidebar and pasting in the sticker pack's URL. Or you can add your own stickers.
• Favorite stickers for easy access by right-clicking on them to add them to your favorites list.
• Send stickers by clicking on them in the app, and they will be automatically pasted to the app you're currently using.

Keep in mind that sticker packs from LINE are created by skilled artists and are sold for use in the LINE app; this application simply aims to let you to use them in other apps. Make sure to support the creators by purchasing the sticker packs you use! LINE supports PayPal and various other payment methods, so purchasing shouldn't be an issue outside of region locks.

Here are the creators whose stickers are shown in the above images:

• 雪子 - Futaribeya mangaka
• 甘城なつき - Nyaa stamps
• 万丈梓 - Mangaka of 恋する(おとめ)の作り方
• ななひら - Nanahira
• こもわた遙華 - Famous SD chibi artist
• まどそふと - Madosoft
• Navel - Navel, featuring 小倉朝日
• clear_blue - Publisher of stickers for Yuzusoft

StampNyaa supports adding your own sticker packs to the app.

• Simply add a folder to the stickers directory in the app's sticker folder, which is located in your {user}/Pictures folder by default.
• The folder name will be used as the sticker pack name by default, and the images inside will be used as the stickers.
• You will also need to add a sticker named main.png to be used as the icon representing the sticker pack in the sidebar.
• Note that only .png images are currently supported.
• After adding new stickers to your stickers directory, press ctrl + r in the app to refresh and your newly added stickers should show up.

• Animated stickers are not supported in certain apps like Discord because they don't support animated pngs for whatever reason 💢. I might add a workaround converting them to gif in the future.
• MacOS users will need to grant the app accessibility permissions for some functions.
• Autoupdate does not work on MacOS nor Linux.

This app would not exist if it were not for jeffshee's LINEStickerKeyboard Android app which I use frequently, inspiring me to build StampNyaa for desktop.

You will also need something to compile the .scss file if you edit any styling. I use Live Sass Compiler for this.
