The psychology behind stickers 

Stickers are an important visual digital language fully capable of communicating a nuanced range of thoughts.
The best stickers go beyond phrases (“I’m hungry”) to depicting full moments of reactions: by showing characters in a relatable scene, or engaged in an everyday act, stickers provide more variables than a simple emoji. 
The most effective stickers capture or exaggerate the feelings of the sender – they are meant to replace text and add social distinction. 


Recommended Stickers

  • Stickers that reflects the meaning of the music snippet. Music snippet is less than 10 seconds.
  • Stickers that are easy to use in daily conversation and communication.
  • Stickers that consist of easily understandable expressions, messages, and illustrations.
  • TIPS: the best stickers are the ones that can completely replace a sentence. 

Non-Recommended Stickers:

  • Stickers that are difficult to use in daily conversation, such as objects and scenery.
  • Stickers that have poor visibility, such as pictures that are too long or full-length illustrations of tall characters.
  • Stickers that significantly lack balance, such as all-pale colored stickers or rows of numbers. 



  • Make sure the PNG files fit the designated dimensions:618x618pixel. 
  • Please do not add margins.
  • Ensure that the size of your GIF is less than 140KB. 


  • Please make sure that your files are in RGB color space.
  • Backgrounds for graphics must be transparent. 


  • Animation that goes along with the music performs better.
  • PNG frame limits per GIF: 8 frames.
  • Playbacktime: 4 seconds.
  • Loops:1–4 loops per sticker whose combined length does not exceed 4 seconds. 

GIF file creation

Step 1: Trim margins

Make graphics within the maximum animated sticker image dimensions: 618x618. 

Step 2: Arrange frame order 

  • When creating stickers, please keep in mind that the first image of the GIF will be displayed as a static image on EmoJam.
  • Select one frame that best expresses the feeling you want to convey with your sticker and set it as the first image.

Step 3: Adjust file size 

  • Compress the size of your PNG files if needed.
  • Your final GIF file should be no larger than 140 KB.

Step 4: Create your GIF 

  • The shorter the length of the loop, the faster your animation will play.
  • Animation can include one or more loops as long as your final GIF is 4 seconds long or under.
  • Set maximum playback time to 4 seconds or less.
  • Once you’re done, save your data as a GIF file.

Step 5: Check your GIF file 

  • Check to see if your GIF file is functioning correctly using Firefox.
  • If so, your animated sticker is now complete!
