Greetings from pixiv.
Starting from May 24th, 2023, the desktop version of pixiv will introduce a new feature, allowing you to edit the thumbnail images for the manga that you post.
Until now, the first page of the manga was set as the thumbnail automatically, but now, you'll be able to choose a page or panel of your preference to use as the thumbnail.
■ Select thumbnail page
You can choose which page you'd like to select as the thumbnail.
■ Thumbnail crop feature
You can crop out a specific panel or scene to set as a thumbnail.
■ Thumbnail zooming feature
You can zoom in the image you use as a thumbnail.
pixiv will continue to make improvements to our service, to ensure a comfortable and fun experience for all our users.
Thank you for your continuing patronage with pixiv.
