Allow margins on all four sides
Leave approximately 10 px margins in the 370 × 320 frame and save at 1 MB or less. You can check whether small text is readable.

What to consider when preparing sticker images
This does not automatically remove backgrounds
Prepare a transparent PNG before loading it. This page does not make white backgrounds transparent or cut out subjects.
Other images are also required for registration
This page adjusts one sticker image. Prepare the main image, chat room tab image, and the set composition for sale separately.
Frequently asked questions
Can I also use JPEG?
This use case is only for PNG files with transparent areas. Simply converting to PNG does not make a white background transparent.
Can I create animated stickers?
This is for static sticker images. Images with multiple frames cannot be loaded.
Is the background checkerboard also saved?
No. The checkerboard is displayed to help you check transparent areas.
