Campaign Ad Builder · by Carl G Studio
One design.
Every ad size.
Write your campaign once. C.A.B lays it out in 20 formats for Instagram, Facebook, LinkedIn, X, YouTube and Google, each one built for its shape, and exports them all at once.
Invite only for now.
How it works
Three steps, and the third one is a single button.
Add your content
Headline, subhead, button text, your logo, a photo and your colours. Once.
See every size, live
All 20 formats update as you type. Aim the photo, adjust the overlay, nudge any size on its own.
Export
One file with every ad at full resolution, each kept under its platform's file size limit.
Real exports, not mockups
Every image on this page came out of C.A.B. One photo, one headline, one button. Shown at their own proportions.
Why not just resize?
A story is 1080 by 1920. A leaderboard is 728 by 90. No amount of scaling makes one layout fit both.
C.A.B keeps your content apart from the layout. Each format gets one of eight layouts, chosen by its shape and its size, so a small banner drops the subhead and keeps the headline and the button readable instead of shrinking everything to nothing.
Built for the details
The parts that usually take an afternoon of nudging in a design tool.
Aim the photo
Set where the subject is once, and every crop keeps it in frame. Override any single size.
An overlay that reads
Flat tint or a gradient you point in any direction, so white text holds up on a bright photo.
Pin the logo and button
Keep them in the flow of the text, or lock them to a corner across every format.
Safe zones shown
Story formats show where the app's own buttons will cover your ad, before you export.
Your projects, kept
Work saves as you go. Save a project as a single file to keep it or move it to another device.
Works on your phone
A layout made for the small screen, so you can put a campaign together away from the desk.
20 formats, 7 platforms
Pick the ones you need. Untick the rest.
