Convert a Meta ad to a ChatGPT ad (free tool, no rewriting)
Updated 2026-06-04
Move your Meta ads to ChatGPT without starting over
The tool above maps your existing Meta (Facebook/Instagram) ad into ChatGPT’s ad format. Paste your headline, primary text, description, and link in the Convert from Meta tab, hit Convert, and you get a ready ChatGPT ad plus a report on what fit and what got trimmed.

Why the two formats are closer than you think
You don’t need a full rewrite — the fields line up almost one-to-one:
| Meta field | Typical display limit | → ChatGPT field | Limit |
|---|---|---|---|
| Headline | ~40 characters | Headline | 40 |
| Primary text | ~125 characters before “See more” | Description | 150 |
| Description (link) | ~30 characters | (not used) | — |
Two things fall out of that table:
- Your Meta headline already fits. Both cap at ~40 characters, so most headlines carry over untouched.
- You gain room in the body. ChatGPT shows up to 150 characters versus Meta’s ~125 truncation point — about 25 extra characters to work with.
Spend the extra characters on curiosity
ChatGPT ads appear inside a high-intent conversation, right after the answer. The reader is already leaning in. So use the headroom to front-load a hook — a number, a question, or a “but…” — in the first ~40 characters, where it’s guaranteed to show before any wrap. The tool flags this for you when there’s unused space.
What gets dropped
ChatGPT ads use only a headline, a description, and a link — there’s no separate link-description field, so your Meta description is set aside. The tool tells you when that happens so nothing surprises you.
