Post previewer for every network
Paste your post to see it as each network would show it. The previewer marks the exact point where a limit ends the text, counts the way each network counts, and lists every rule your text or images break. It runs entirely in your browser, so nothing you write is uploaded or stored.
Read in your browser, never uploaded.

How it works
- 01
Type or paste your post, then pick the networks you care about. For each one the previewer counts characters by that network's own rule, so a link on X weighs 23 however long it is, and draws a mark where the limit falls.
- 02
Add pictures if you want the media rules checked too. Image shape, size and count are tested against each network's published limits, and the previewer tells you which networks would refuse the post and why.
- 03
Copy a link to the result, or open it in the composer with 1Post and schedule it to every network.
What it checks
- Text lengthCounted by each network's own rule, so a link on X weighs 23 however long it is.
- The cut pointA mark shows exactly where a network's limit would end your text.
- Image count, shape and sizeEach picture is tested against the network's published image limits.
- Media neededA network that takes images only, or text only, says so beside the preview.
It runs in your browser. Nothing you type or choose is uploaded, and the page works without an account. To publish what you made, start a trial and open it in the composer.
Questions
Does the previewer show the exact look of each app?
It shows the text, the cut point and the rule results. Each network changes its own layout often, so the previewer does not copy it; it tells you what will fit and what will be refused.
Is my post uploaded anywhere?
No. The tool runs in your browser and nothing leaves it. The address can carry your text if you press the share button, and only then.
Can I publish from here?
The previewer is free and needs no account. To publish, start a trial and your post opens in the composer with the same previews.
