Preview
Your images are read by this browser and never uploaded. Nothing is saved.
This LinkedIn post preview lays your text out the way the feed lays it out, with the cut where LinkedIn puts it. Paste a post into the editor and it renders beside it as you type, with up to nine images paged one at a time.
LinkedIn hides most of a post behind “…see more”, and the boundary is not the same on every device: roughly 140 characters on a phone, about 210 on a desktop feed. A hook written to land at 200 characters therefore reads complete on a laptop and arrives cut in half on mobile, where most of the feed is read. The toggle above the preview switches between the two.
Two things survive the feed less well than people expect. Runs of empty lines get collapsed, so spacing added for rhythm often reads tighter than the draft did. And a link in the body becomes a preview card under the text, which changes the shape of the whole post — attach an image as well and LinkedIn shows the image instead.
Nothing here is uploaded. The image you pick is read by your own browser and never leaves it, and nothing is kept when you close the tab.
Questions
How much of a LinkedIn post shows before “see more”?
About 140 characters on mobile and about 210 on desktop. LinkedIn does not publish the numbers and has changed them before, so treat them as close rather than exact.
Will my line breaks show up the way I typed them?
Single breaks will. Runs of empty lines are collapsed, so a post spaced out for rhythm usually reads tighter in the feed than in your draft.
Does this tool upload my image anywhere?
No. The image is read inside your browser and never sent to us or to anyone else. Closing the tab discards it.
How long can a LinkedIn post be?
3,000 characters. Almost nobody reaches it — the number that decides whether a post gets read is the ~140 visible before the cut.
Is this an official LinkedIn tool?
No. It is a layout approximation built by PostPost.ai, and it is not affiliated with LinkedIn.
