Frequently asked questions
Does it support regular expressions?
No — deliberately. Matching is literal, so characters like * and ( are treated as plain text. You always know exactly what will be replaced.
Can I replace every occurrence?
Yes. The "all" option replaces every match; turn it off to replace only the first occurrence. Empty search strings are rejected with a clear error.
Is matching case-sensitive?
By default yes. Disable case sensitivity to match "Word", "word" and "WORD" identically.
Is my text sent anywhere?
No. The replacement runs entirely in your browser — nothing is uploaded, logged or stored.
Literal find and replace
Here is what each format is for, and when converting old text swapped for new is the right move.
What is Replaced output?
The same text with exact literal matches swapped for your replacement, everywhere or once, in the same order — fully predictable and reviewable.
When you need it
Use it for renaming placeholders, updating IDs across logs or config, fixing repeated typos, or template-style substitutions. Literal matching means special characters need no escaping — what you type is exactly what gets matched.
