Ban-risk and rate-limit safety on Facebook

Humanized posting delays

Meta flags identical text repeated across Pages. GentoPost's per-network rewrite keeps each Page variant distinct.

Official API only

Meta Graph API via official Facebook OAuth 2.0 with pages_manage_posts. No scraping, no session cookies, no unofficial endpoints — the practices that actually get accounts suspended.

Compression before upload

WebCodecs re-encodes on your device — a 100 MB clip becomes roughly 12 MB — so Facebook uploads finish fast and stay inside its size ceiling. Try the compressor.

Facebook publishing questions

Specifics about limits, media and compliance when GentoPost posts to Facebook.

What is the Facebook character limit in GentoPost?

63,206 characters — effectively unlimited for social copy — but the composer still shows the live count so cross-posted versions stay readable.

Can I publish to a Page and an Instagram account together?

Yes. One Meta sign-in covers both, and each destination receives its own adapted caption and aspect ratio.
