Frequently asked questions
Can I use regular expressions?+
Yes. Switch “Match type” to Regex to use full JavaScript regular expression syntax in the find field, including capture groups referenced in the replacement with $1, $2, etc.
Does plain mode treat “$” specially?+
No. In plain (non-regex) mode, the replacement text is treated completely literally — a "$" or "&" in your replacement is inserted as-is, not interpreted as a special pattern.
Is matching case-sensitive by default?+
Yes, matching is case-sensitive by default; turn off “Case-sensitive” to match regardless of letter case.
Is my text uploaded anywhere?+
No. The find-and-replace operation runs entirely in your browser — nothing is sent to a server.
