Publishes to all 11 platforms: LinkedIn, Instagram, Facebook, X, YouTube, TikTok, Pinterest, Threads, Google Business, Bluesky and Mastodon.
Why Instagram posting slips
Posting when you remember
Instagram rewards a steady rhythm, and posting in bursts then stopping resets it.
Finding out at the last minute
A caption over Instagram's limit, or the wrong kind of media, is only refused when you press Post.
One app per platform
Opening Instagram, then every other app, to post the same news is slow and easy to forget.
How Optimate schedules Instagram
Write it once, check it against Instagram's own rules, and pick a time. It publishes while you get on with your day.
One calendar for every platform
Instagram sits on the same planner as LinkedIn, Facebook, X, YouTube, TikTok, Pinterest, Threads, Google Business, Bluesky and Mastodon.
Checked against Instagram's rules
The caption is counted as you type and the media checked before it is queued, so a post Instagram would refuse is caught before it is scheduled.
Tailored per platform
Post the same news everywhere, with the wording adjusted for Instagram, and preview it the way Instagram will show it.
Post now or later
Pick a time, or publish straight away when something can't wait.

Common questions
Can I schedule Instagram posts for free?
Yes. Every new account starts with a 14-day free trial, no card needed, and the Free plan afterwards keeps a small queue of scheduled posts.
What is Instagram's character limit?
2,200 characters for a post or caption. Optimate counts as you type and warns before you schedule anything Instagram would refuse.
What can I attach to a Instagram post?
Every Instagram post needs a photo or video: up to 10 in a carousel. Reels videos up to 15 minutes.
Can I post the same thing to Instagram and other platforms?
Yes. Write one post, tick every platform it should go to, and adjust the wording for each one before it is scheduled.

Every size Instagram asks for, from posts to profile pictures, on one page with every other platform's.
