FallenStickers

Add pictures to your own Telegram sticker pack in one click — right-click → Send to → Telegram sticker.

No more /addsticker, resizing to 512 px, exporting PNG, sending as a file, choosing an emoji and /done by hand. FallenStickers does the whole @Stickers routine for you, from your own Telegram account.

Features

• Send to / drag & drop – one or many pictures at once
• Automatic resize to 512 px on the long side, PNG under 512 KB, EXIF rotation, transparency kept
• Text on stickers – any installed font, size, color, outline, bold, drag to position, live preview
• Emoji per sticker, with a quick emoji row
• Pick your pack from a list – your own sticker packs are read straight from Telegram
• Romanian / English interface
• Everything stays on your PC – no server, no third party, only Telegram itself

Download

Get the latest zip from Releases, unzip and run FallenStickers.exe. Requires Windows 10/11 and the .NET 8 Desktop Runtime.

Getting started (one time only)

1. api_id / api_hash – go to my.telegram.org/apps, log in with your phone number, open API development tools and create an app (any title / short name, platform Desktop). Copy App api_id and App api_hash into FallenStickers. They are yours — don't share them.
2. A sticker pack (only if you don't have one) – in Telegram open @Stickers, send /newpack, give it a name, send a first 512 px PNG as a file and an emoji, then /publish, /skip for the icon and choose the short name.
3. Phone + pack – enter your phone number (with country code) and press Choose… next to Pack. The first time you will get a login code in Telegram (and your 2FA password is asked if you have one). Then pick your pack.
4. Press Add to Send to menu. Done — right-click pictures → Send to → Telegram sticker.

How it works

FallenStickers is a small Telegram client (MTProto, via WTelegramClient) that logs in as you and chats with the official @Stickers bot exactly like you would: /addsticker → pack → file → emoji → /done. This is needed because packs created with @Stickers can only be edited by their owner (the Bot API cannot add to them).

Privacy

• api_id, api_hash, phone number and the Telegram session (session.dat) are stored only in %APPDATA%\FallenStickers on your PC.
• session.dat gives access to your Telegram account — never share it. Log out in the app deletes it.
• The app connects only to Telegram's servers. The source code is right here.
