Image sizes for every platform, how AI image generation and credits work, and what happens to the files in your library.
Sizes & dimensions
What size is an Instagram post?
Square, 1:1 — 1080×1080 px is the standard. Brandmundo generates and previews Instagram singles and carousels in exactly that ratio, so nothing gets cropped.
What are the Instagram Story and Reel dimensions?
Both are 9:16 portrait — 1080×1920 px. Generated media for Stories and Reels comes out in that ratio automatically.
What size is a Facebook post image?
Feed posts work best around 3:2 landscape (e.g. 1200×800 px); Facebook Reels are 9:16 like Instagram’s. Brandmundo uses the right one per format.
What’s the right LinkedIn image size?
LinkedIn rewards tall 4:5 images in the feed (e.g. 1080×1350 px) — they take up more screen. That’s the ratio Brandmundo generates for LinkedIn posts and documents.
What’s a LinkedIn carousel post?
A multi-page document (LinkedIn calls it a document post) that readers swipe through — great for tips, steps and mini-guides, and one of LinkedIn’s highest-engagement formats. It’s a built-in Brandmundo format: generated LinkedIn ideas often arrive as documents with the pages outlined for you.
What’s the TikTok video size?
Full-screen 9:16 portrait, 1080×1920 px. There’s a full per-platform reference table in this collection: "Image sizes and formats by platform".
AI images
How much does an AI image cost?
5 credits per render, including regenerations. New accounts get 30 welcome credits, paid plans include a monthly allowance, and top-up packs never expire.
Can I use AI-generated images on Instagram?
Yes — there’s no rule against it. Platforms may label AI-generated media, and the same advice applies as for stock photos: it works best for illustrative posts, while real photos of your actual work and team build the most trust. Most brands mix both.
Do I have to write image prompts?
No. Brandmundo builds the prompt from your caption and brand profile — colors, logo character, style references. Keeping Brand assets filled in is what makes generated images feel designed for you.
Your library
Can I upload my own photos?
Yes — JPEG, PNG or WebP images and videos go into your media library and can be attached to any post from the composer. Real photos of your business often outperform anything generated.
What happens when I delete a photo?
It moves to the trash for 30 days, restorable with one tap. After that it’s gone for good and stops counting against your storage.
How much storage do I get?
200 MB on Free, 2 GB on Starter, 20 GB on Growth and 100 GB on Studio.
