For Marketers
Ship the whole campaign, not just the first size.
Launch across social, display and email from one master banner. Buno builds every size, fits your captions to each platform and exports it all in one ZIP.
Free to start. No credit card. No design skills needed.
Problem
You signed up to run campaigns, not to rebuild the same banner 20 times. Every channel adds hours, and every resize is a chance for the logo to drift or the text to get cut.
You make one master banner. Buno makes every other size and checks each one before you export.
How it works
From one idea to every size in four steps.
- 01
Start.
Blank canvas, your own image, or a design from your AI assistant.
- 02
Design your master.
Headline, images, logo, brand colours.
- 03
Generate every size.
Pick platforms or a quick pack. Buno lays out each one.
- 04
Export and post.
PNG, JPG, WebP or PDF, every size in one ZIP, with captions ready to paste.

Frequently asked questions
Which channels are covered?
37 sizes across Instagram, Facebook, LinkedIn, X, TikTok, YouTube, Pinterest, display ads and email. You can add custom sizes too.

Does Buno post to my accounts?
Not directly. Buno prepares every image and caption; you post with the tools you already use.
Is Buno free?
Yes, you can start for free. No credit card needed.
Buno for other teams.
