PixelFed is the Fediverse's alternative to Instagram, with a similar interface and range of features.
Because it's part of the Fediverse, you can follow PixelFed accounts from Mastodon and vice versa.
The web interface is good, and there's an unofficial Android app PixelDroid available through F-Droid.
@feditips can not upload my Instagram Video think because the size is too big more than fifty Megabyte.
Discover & explore Mastodon with no ads and no surveillance. Publish anything you want on Mastodon: links, pictures, text, audio & video.
All on a platform that is community-owned and ad-free.
