FAQ
Can I submit stickers I created on mobile from a PC?
Yes. Stampo ZIPs work in LINE Creators Market regardless of where they were created. Stickers are saved to the cloud — sign in on another device and download the ZIP from the PC.
What software unzips the ZIP?
Windows and Mac's built-in tools work. Windows: right-click → 'Extract all'. Mac: double-click. No extra software needed.
Which browser should I use?
Chrome / Edge / Safari / Firefox all work. Keeping your browser up to date reduces upload errors.
What if I see an error during submission?
If you see 'out of spec' errors, reopen the Stampo editor and re-download the latest ZIP. For 'image count mismatch', check that you have 8/16/24/32/40 images as expected.
Download your ZIP directly from Stampo's editor
Stampo runs in the browser, so editing → ZIP download flows perfectly on PC too.
