Blank lines pile up when you paste from email, copy from a PDF, or merge files. This tool drops them entirely, or — in collapse mode — squashes runs of multiple blanks into a single blank line so paragraph structure stays intact. Useful for cleaning logs, normalising configuration files, prepping text for diffing, and removing the awkward gaps that appear after exporting from word processors.
Drop the raw text into the input box — it accepts anything from a single line to a full document.
Click the button to apply the "Remove Empty Lines" operation in a single pass, entirely inside your browser.
Compare the original and transformed text side by side to verify the change is exactly what you expected.
Copy the result to your clipboard or download it as a plain-text file.
Remove Empty Lines does one small thing well. Cleaning up pasted text is the kind of task you do dozens of times a week — copied from a PDF, exported from a CMS, generated by another tool — and each time you lose a couple of minutes to fiddly regex or find-and-replace. This tool applies the change instantly and gives you the cleaned output ready to paste. Toolzer's design philosophy is simple: privacy-first (no tracking, no accounts), performance-first (the page is interactive in under a second on a 3G connection), and honesty-first (no fake ratings, no dark patterns, no upsells). Remove Empty Lines follows the same rules as every other utility on the site. You can bookmark this page, share the URL with a colleague, or pin it to your browser's toolbar — the experience will be identical every visit, and it will keep working even if you're on airplane Wi-Fi. Real people use this tool for real work — freelancers cleaning up client deliverables, sysadmins triaging tickets, students finishing assignments — and it is tuned for those workflows, not for demo videos.
Remove deletes every blank line. Collapse keeps one blank between paragraphs but removes additional ones, which is what you usually want for prose.
