NEW YORK — Instagram, the photo-sharing app that was created for mobile phones, is expanding to the Web.

The service will launch Instagram­ profiles on the Web over the next few days. Previously, users’ profiles existed only on Instagram’s mobile applications accessed on the iPhone or Android devices. Now, users will have a website with a profile photo, bio, and a selection of the snapshots they have recently shared on Instagram.

Instragram, which is owned by Facebook Inc., made its announcement in a blog post Monday.

The layout of the Web profiles is reminiscent of Facebook timelines, except with little text and no ads. Users will have a large cover image that’s a collage of their old Instagram­ shots. Their profile photo is on the right side, and their snapshots cascade down the page.

Facebook has insisted since it bought Instagram this year that it will keep it running as a separate service. That still appears to be the case.

The Instagram Web pages don’t link to Facebook and don’t ask users to log in using their Facebook accounts.
