Does it support regular expressions?

Yes — enable the regex option to use patterns and capture groups. With regex off, your search text is matched literally.

How many matches does it replace?

All matches are replaced at once, and a live count tells you how many replacements were made.

Can I use capture groups in the replacement?

Yes, with regex mode on. Wrap part of your pattern in parentheses and reference it in the replacement with $1, $2 and so on. For example, find (\\w+)@ and replace with $1[at] to rewrite email handles.

How do I match across line breaks or whole words only?

Use regex mode. \\b marks a word boundary so cat does not match cats, and patterns like .* match within a line. Enable case-insensitive matching to ignore upper/lower case.

Is my text sent to a server?

No — find and replace runs entirely in your browser and nothing is uploaded.

Find and Replace Text

Find and replace text

Cleaning up a document, renaming a term across a code snippet, or reformatting pasted data all come down to the same task: swap every occurrence of one string for another. This tool does bulk find-and-replace on any text you paste, with an optional regular-expression mode for patterns the simple version cannot reach, and a live count of how many replacements it made.

How it works

Paste your text, type what to find and what to replace it with, and the result updates instantly. With regex off, the find value is matched literally — every exact occurrence is swapped. With regex on, the find value is treated as a JavaScript regular expression, so you can use character classes, anchors, word boundaries and capture groups (referenced as $1, $2 in the replacement). The case-insensitive toggle ignores letter case while matching. All matches are replaced in one pass and the replacement count tells you how many were made.

Example

Literal replace — find colour, replace color in a paragraph: every colour becomes color and the count shows the total swapped.

Regex replace — turn 2026-05-30 style dates into 30/05/2026:

Find (regex on): (\d{4})-(\d{2})-(\d{2})
Replace: $3/$2/$1

Mode	Find	Replace	Result
Literal	cat	dog	”the dog sat”
Case-insensitive	the	a	”a Cat sat”
Regex	`\s+`	(single space)	collapses runs of whitespace

All processing happens in your browser — nothing is uploaded.
