Instagram Caption Editor
About this Tool
AllThatConverter's Instagram Caption Editor is an all-in-one assistant supporting both feed post captions (2,200 characters) and profile bios (150 characters). It applies U+2800 blank-line preservation in real time to prevent collapsed paragraphs, generates smart AI hashtag recommendations (recommended 3–5 tags) based on caption context, and provides live previews for the 125-character '…more' cutoff and mobile profile layouts—100% locally in your browser.
