- Set the number of copies (1 to 10,000).
- Pick a separator between copies — newline, single space, comma, no separator, or a custom string.
- Press Repeat to generate the output. The result panel shows the total character count.
- Press Copy result to copy everything to your clipboard, or Reset to start over.
About this text repeater
The text repeater builds an array of N identical copies of your input and joins them with the chosen separator. It does this in a single pass with no per-character iteration, so even the maximum count (10,000) runs instantly on any modern device. A 5 MB safety cap on the total output size prevents accidentally producing a string that would crash the browser tab.
A concrete example. Input text: `"ping"`. Count: `5`. Separator: comma + space.
Output: `ping, ping, ping, ping, ping` (28 characters total).
Switch the separator to "newline" and you get five lines of `ping`. Switch to "no separator" and you get `pingpingpingpingping`. The custom separator option lets you use any string — useful for building test fixtures (`"item|item|item"`), padding payloads, simulating chat-flood input, or stress-testing UI components that render long strings. All processing is local: nothing leaves your browser.
FAQ
- What is the maximum repeat count?
- The tool accepts up to 10,000 repeats. There is also a separate 5 MB cap on the total output size, so very long inputs at the maximum count may be rejected — reduce the count or shorten the input if you hit that limit.
- Can I use multi-line text as the repeated unit?
- Yes. The "Text to repeat" field is a multi-line textarea, so you can paste a paragraph or several lines and they will be repeated as a block separated by your chosen separator.
- What does the "no separator" option produce?
- It concatenates the copies with nothing between them. For an input of "ab" repeated 3 times you get "ababab". This is the same as JavaScript's built-in `String.prototype.repeat` method.
- Does the custom separator support newlines or tabs?
- You can type a normal space, comma, pipe, or any printable character into the custom separator field. To get a newline or tab, switch to the newline preset or paste the special character directly.
- Why is the output size capped?
- Beyond ~5 MB of text, the browser may freeze or run out of memory when allocating the result. The cap protects you from accidentally producing a string that would crash the tab.
- Is the input or output stored anywhere?
- No. The repeater runs entirely in your browser — input and output exist only in the current tab and are discarded when you close it.
