Fix Double Punctuation

Accidental double punctuation — a stray extra comma, an accidental double period — creeps in easily during editing, especially when moving sentences around or merging edits from multiple sources.

This tool scans for repeated punctuation marks sitting next to each other and collapses them down to a single mark, while specifically preserving legitimate ellipses (three dots in a row) since those are intentional.

This is a quick final proofreading pass that catches a mechanical error spell-checkers typically don't flag, since the individual punctuation marks are each valid on their own.

This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.

A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.

If you find yourself needing this often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.

Because there's no sign-up or installation step, you can jump straight from a search result to a working tool in a couple of seconds.

The interface is intentionally simple, so there's no learning curve — the input goes in, the result comes out, and that's the whole interaction.

Unlike a heavier desktop application, there's nothing to download, update, or configure before you can start using this tool.

Because the calculation or conversion happens instantly as you type, you can experiment freely and see how changing one value affects the result.
