Free Facebook Tools
Everything on this page runs in your browser or on our AI, without an account. Facebook posts and comments have no formatting buttons on the page itself, so bold and italic only exist as Unicode characters. The post limit is a generous 63,206 characters, but the feed folds anything past a few lines behind "See more", and posts under 80 characters historically get the most engagement. The tools below handle the formatting, counting, previewing and writing; the scheduler handles the posting.

Facebook limits and sizes at a glance
The post limit is a generous 63,206 characters, but the feed folds anything past a few lines behind "See more", and posts under 80 characters historically get the most engagement. The page intro is 101 characters and ad primary text is cut at 125 in feed placements.
Posting on Facebook in 2026
Short posts win on Facebook. One idea, a plain first sentence, and the link in the post rather than the comments: Facebook stopped penalising links in 2023.
Hashtags on Facebook are clickable but do almost nothing for reach; one or two for context is plenty, and a post full of tags reads like it was cross-posted from Instagram.

Formatting support on Facebook
Facebook posts and comments have no bold or italic buttons. Unicode styled text is the only way to add emphasis in a post; Facebook Notes and group posts on desktop support limited formatting.
Line breaks are preserved; use "•" for bullets.

Hashtags barely affect reach on Facebook; one or two for context is plenty. Limit: none. Sweet spot: 1–2.
