A Facebook scheduler for the whole job, not just the post
Posts, photos, videos, Reels and Stories for your Pages — and the comments, Messenger conversations and reviews they generate, in the same tool.
Scheduling to Facebook is the easy half of running a Page: the post goes out, and then the actual work starts — comments to answer, Messenger messages to not lose, reviews to respond to.
Most Facebook schedulers stop at publishing. This one is also the inbox for what comes back, and the automation that answers a comment with a private message — Facebook is one of only two networks where that private-reply move exists at all.
On the publishing side, Facebook has quirks of its own — a surprisingly small image limit, and formats that refuse to share a post. What Ignix checks is below, with the numbers.
What you can schedule on a Facebook Page
Facebook is the least fussy network about formats — it is the limits inside them that catch people.
Post
Text alone is fine on Facebook — unlike Instagram — and the composer treats it as a first-class format. The technical cap is famously enormous (63,206 characters); nobody should go near it.
Photo post
Up to 10 photos in one post — JPEG, PNG, GIF or WebP. Facebook accepts the two formats Instagram refuses, which matters when the same post goes to both.
Video
One video, mp4 or mov, up to 4 GB. Photos and video do not mix in a single Facebook post — that pairing is what carousels on other networks allow and Facebook does not.
Reel & Story
Both schedulable. A vertical video can go out as a Reel, and the composer tells you which format the post is going to be before you queue it.
The four things that make a Facebook post fail
Fewer traps than Instagram, but the ones that exist are quieter. Each is checked before the post is queued.
The image is over 4 MB
Facebook’s API takes images up to 4 MB — half of Instagram’s 8 and the smallest of the big networks. It is the classic silent failure of cross-posting: the same photo sails through Instagram and dies on Facebook.
In Ignix: Size is checked on upload, per network: you see “fine for Instagram, too heavy for Facebook” while you are still writing, not in a failure notice hours later.
A photo and a video in the same post
Facebook refuses posts that mix them. People hit this when they reuse an Instagram carousel that mixes photos and clips — valid there, refused here.
In Ignix: The composer warns as soon as the combination appears for a Facebook target, before anything is queued.
Trying to publish to a personal profile
Facebook’s API publishes to Pages you manage — not personal profiles. That is Facebook’s rule, and any tool that claims otherwise is doing something that risks the account.
In Ignix: The connect flow lists the Pages your login manages and connects those. What you see is what can actually be published to.
The wrong format for the moment
Facebook takes text posts, photo posts, videos, Reels and Stories — five different shapes with different rules, and a vertical video could be a feed video or a Reel.
In Ignix: The composer shows which format each network is getting before you queue, so the post that goes out is the one you meant.
One of two networks where comments become DMs
The private reply — someone comments on your post and gets an automatic private message — exists on exactly two networks: Instagram and Facebook. Meta’s rules, not ours.
On Facebook that means “comment PRICE and I will message you the catalogue” works on your Page posts, with the same builder, follow-up flows and A/B testing as on Instagram. The conversation lands in the same inbox as everything else.
Comments, Messenger and reviews in one inbox
A Facebook Page generates three kinds of conversation: comments on posts, Messenger messages, and reviews. Ignix puts the three in one inbox, next to every other network — answered from the same box, by you or by the AI trained on your business.
Reviews matter more than they look: they are where a Page wins or loses local customers, and they are the easiest thing to forget when they live in a tab you never open.
Your best hour, from your own Page
Analytics builds a “Best time to post” heatmap from what your own posts earned, weekday by hour, in your timezone. It is your Page’s history, not an industry average.
On the official API, with no password
You authorise Ignix from Facebook’s own site, through the official API. We store no password and no access token; you can revoke the authorisation from Facebook itself at any time.
Longer read: the best time to post on Instagram — and what outranks it.
Questions people ask
Can I schedule to a personal Facebook profile?
No — and not with any compliant tool. Facebook’s API publishes to Pages you manage. If a tool claims to post to personal profiles, it is automating a browser pretending to be you, which is the kind of shortcut that gets accounts restricted.
Can I schedule Facebook Reels and Stories?
Yes, both, through the official API. A vertical video can publish as a Reel, and the composer shows which format each post will be before you queue it.
Why did my cross-posted photo fail on Facebook but publish on Instagram?
Almost always size: Facebook’s API caps images at 4 MB, half of Instagram’s 8. Ignix checks the file per network on upload, so the mismatch shows up while you are writing. The reverse trap also exists: Facebook takes GIF and WebP and Instagram does not.
Does comment-to-DM work on Facebook?
Yes — Facebook and Instagram are the only two networks where a comment can trigger an automatic private message, and both work here with the same flow builder, follower checks and A/B testing.
Can I answer Messenger and reviews from the same place?
Yes. Comments, Messenger conversations and Page reviews land in one inbox alongside your other networks, with saved replies, media, team assignment and an AI agent that knows when to hand over to you.
Schedule the Page, then answer everything it brings
Posts, Reels and Stories on one calendar, the checks that catch what Facebook refuses, and the comments, Messenger threads and reviews that follow — in one inbox, at one flat price.
