Social post preview
Review your opening lines and image together before posting. Try a LinkedIn or Instagram post, or a YouTube title and thumbnail. Compare two screen widths and download a clearly marked review image.
Approximate mobile preview
How to use it
- 1
Choose LinkedIn, Instagram or YouTube, then type your caption or video title and the name you post as.
- 2
Drop in your image or thumbnail, and an avatar if you like. Show the whole image or crop it to fill the frame.
- 3
Switch between mobile and desktop widths, and between the opening lines and all of your text, to see where the post folds.
- 4
Download the review image to share for feedback, then publish your original media as usual.
Before you export
These are approximate review layouts. Platforms change their typography, media crops and collapsed text behavior. A title’s visual clipping is separate from its allowed length. YouTube publishes a 100-character title limit; the editor shows both Unicode code points and UTF-16 units so emoji differences remain visible.
Link cards use manually entered text, with no URL fetching. Images and avatars remain in memory until you leave the page. The downloadable mockup includes a label and is intended for review, not as a substitute for your original post image.
Need another crop or exact output size? Use the image resizer. Review captions with the character counter.
