Find & Replace Text Online

Fill in Find and Replace with; the right column shows how many non-overlapping hits were swapped, how the character count shifted, plus words and read time. Copy replaced text grabs only the new version.

Find and replace input and live preview

Plain-text search only: the page walks your string left to right, swaps each matching span, then keeps scanning after that span so you get predictable bulk edits without regex.

Live replaced output

Sample: find TODO → replace DONE. Turn off Match case to treat cat and CAT as the same. Special characters in your find string are treated literally, not as patterns.

Source text and both fields stay in this tab until you reload or clear them.

  • Replacements are computed in your browser from what you typed
  • Good for renaming a label or typo across a single paste
  • Match count helps you spot zero hits before you ship the wrong string
  • For regex or multi-file edits, use a full editor

Length & format benchmarks

Rough article lengths people cite in specs—always match the doc you are actually filing.

  • Blog posts: ~800-2,000 words is a common full-article band before you split into a series.
  • SEO explainers: ~1,000-2,500 words when you need depth, headings, and internal links without filler.
  • Social: ~100-300 characters for a tight single post; threads need clear breaks.
  • Academic abstracts: often ~150-300 words-always match the venue PDF.

What this is for

You have one long blob—release notes, a customer email, a JSON slice—and need to rename a token or kill a repeated phrase without firing up a project in an IDE.

  • Renaming a product code or placeholder that appears dozens of times
  • Checking whether anything matched before you paste into a ticket
  • Seeing how much shorter or longer the text became after deletions
  • Teaching someone what “replace all” does on a single string

Heads-up: Need patterns like \d+? Use an editor with regex-this page stays intentionally simple.

If you live in support queues, keep this next to your snippet scratchpad.

When this beats a full editor

Word processors hide find/replace behind ribbons; IDEs want a workspace. Here you get a match count and length delta on a one-off paste, then you leave with clipboard text.

How it works

  1. Put the full source in the big box.
  2. Set Find / Replace with and flip Match case when an acronym must stay exact.
  3. When the count looks right, press Copy replaced text; the stats never travel with the clipboard payload.

Privacy: We do not receive your textarea or the find/replace fields for processing.

FAQ

  • Does this upload my text? The swap runs here; only you decide what to copy out.
  • What does the big number mean? It is how many times the find string matched and was replaced in one pass (0 if nothing matched).
  • What is “first match at character”? It is the 1-based position of the first occurrence in your source text (from the start). When the count is 0, the panel instead explains that nothing matched and suggests checking quotes, spaces, or Match case.
  • Regex or wildcards? No-find is literal text. Case-insensitive mode escapes special characters automatically.
  • Empty replace field? Matches are removed (deleted) from the preview.
  • Can I use it on my phone? Yes—the textarea and find/replace rows stack above the preview; scroll the result if it is tall, then copy the same as on desktop.

Editors and developers keep a find/replace tab open-save this URL for the next bulk rename.
