Add Suffix Each Line
Paste a newline-separated block, enter a suffix, and create a local text result with that suffix appended to every non-blank line.
Add suffix to each line
A QUICK WALKTHROUGH
How to use this tool
- Paste up to 50,000 characters of text.
- Enter a suffix of up to 200 characters.
- Add the suffix, then copy the result or download it as plain text.
Suffix-only line formatting
The tool appends the exact suffix to every line containing a non-whitespace character. Empty and whitespace-only lines are unchanged, and indentation or trailing spaces on other lines remain in place.
Bounded local processing
Text is processed only in this browser. Input is limited to 50,000 characters, the suffix to 200 characters, and the generated output to 500,000 characters.
GOOD TO KNOW
Common questions
Can I add a prefix too?
This focused tool appends a suffix only. Use Prefix Suffix Adder when you need a prefix, suffix, or both.
What happens to blank lines?
Empty and whitespace-only lines stay unchanged, including their original line endings.
Is my text uploaded?
No. Formatting, copying, and downloading happen in your browser.
