Telegram Sticker Pack Requirements (512px Rule)
Telegram is very strict about stickers. If you don't follow the 512px rule, your pack will be rejected.
1
The 512px Rule
One side of your sticker MUST be exactly **512 pixels**. The other side must be 512px or less.
2
White Stroke
Telegram recommends adding a white stroke (outline) and a shadow to ensure your sticker is visible on all wallpapers.
3
Format
Must be **PNG** with transparency. WebP is used internally by Telegram but you upload PNGs to the bot.
