About Replace Suffix
Replace Suffix looks for a given suffix on each line and replaces it — only when the line actually ends with it.
It is useful for changing file extensions, end punctuation, or line-end markers.
FAQ
Is my text sent to a server?
No. Replace Suffix runs entirely in your browser — the text you enter never leaves your device.
