Do I have to post my work on pixiv?

A request is completed and the creator's profits are finalized when a work is submitted to pixiv. For this reason, we ask that you post your finished work to pixiv.

This feature was thought to support the motivation and the creative activities of pixiv creators. The works you create as part of a request are part of your work as an artist, and the works you post will form your portfolio on pixiv.
For this reason, a request is considered complete when you post your work on pixiv.

However, there may be times when you may feel that the work you have been requested does not fit your portfolio. In this case, you can choose to make your work URL restricted.

If you want to send a file in a format different from pixiv standards, such as a PSD file, please use a gift file.
