The "Join Text" tool is a free utility that merges the separate lines of your text into a single continuous string, connecting each line with a character you choose - a space by default. Paste in a column of words or a bullet list and get back one clean line, ready to copy, download, or paste wherever you need it.
Two cleanup switches sit in the options: Delete blank lines and Delete trailing spaces, both on by default, so stray empty lines and ragged spacing never spoil the joined result. Leave the join character empty to remove the line breaks completely.
Everything runs locally in your browser, so your text never leaves your device and nothing is ever uploaded or stored. The tool is free to use, needs no account, and works on any device with a modern browser.
