Text Repeater

Repeat exact text up to 10,000 times with a custom separator while preserving multiline content and every boundary character.

Privacy: your files never leave your device. All processing happens locally in your browser.

How to use

  1. 1.Enter the exact source text to duplicate.
  2. 2.Choose a whole-number repeat count and type the precise between-copy separator.
  3. 3.Repeat the text, inspect the boundaries and output length, then download the TXT result.

About Text Repeater

Text Repeater duplicates a source string a chosen number of times and inserts an exact separator only between adjacent copies. Paste or type the source, choose a repeat count from one through 10,000, enter any separator, and generate the result. The complete output can be reviewed and downloaded as UTF-8 plain text without uploading content to Lizely.

The source is copied exactly. Capitalization, punctuation, spaces, tabs, line breaks, emoji, and other Unicode characters are preserved. The tool does not trim, normalize, reformat, spell-check, or interpret the text. A multiline source remains multiline in every copy.

The separator is inserted count minus one times. It never appears before the first copy or after the last copy. With source “go”, count three, and one space, the exact result is “go go go”. With an empty separator, copies touch directly. With an LF separator, each copy begins on the next line.

The separator field is a small textarea so spaces, tabs pasted from another source, and line breaks can be represented directly. What is entered is what is inserted. The tool does not interpret backslash sequences, so the two visible characters backslash and n remain “\n”; press Enter in the separator field when an actual line break is required.

Repeat count must be a positive whole number. A count of one returns the source unchanged and ignores the separator because there is no boundary between copies. Zero, negative, decimal, missing, and nonnumeric counts are rejected. The source itself must contain at least one character.

Output is limited to 1,000,000 Unicode code points. Before allocation, the tool computes source length multiplied by count plus separator length multiplied by count minus one. A result exactly at the limit is accepted, while one code point beyond it is rejected without producing a partial string.

Length uses JavaScript string iteration, which counts Unicode code points rather than UTF-16 code units. A basic emoji is normally one code point, but joined emoji, flags, combining marks, and other visible grapheme clusters can contain several. The reported number is therefore not a byte count or guaranteed visual-character count.

Use the repeater for test fixtures, repeated labels, simple chant or caption layouts, delimiter-separated samples, placeholder blocks, stress-test strings within the limit, and duplicating a multiline snippet. For sequential values, use Text Pattern Generator instead. For adding material once to every input line, use Add Prefix or Suffix.

This utility is not a load-testing system and should not be used to flood a form, endpoint, message service, or third-party platform. It creates local text only. Respect destination limits, anti-spam policies, copyright, and community rules before pasting a large repeated result elsewhere.

Repeated whitespace can be visually hard to distinguish, especially when the separator is empty or contains only spaces. Check the reported code-point length and select the preview when exact boundaries matter. Destination editors may normalize line endings or trim trailing whitespace after paste, which is outside this tool's control.

Download creates a Blob from the final JavaScript string with a UTF-8 plain-text MIME type. A temporary object URL is created only when the button is clicked and is scheduled for immediate revocation after the browser begins the download. Editing the source, count, or separator clears the old result.

No server, account, random source, dictionary, or external dataset participates in the operation. The same accepted source, count, and separator always produce the same string. Keep the original material until the downloaded output has been opened and verified in its destination application.

Methodology & sources

Validate nonempty visitor text and a whole-number repeat count from one through 10,000, iterate source and separator by Unicode code point, calculate source length times count plus separator length times count minus one before allocation, reject output above 1,000,000 code points, join exact source copies with the exact visitor-supplied separator, and create and immediately revoke a temporary UTF-8 Blob URL only when download is clicked.

Frequently asked questions

Is the separator added after the last copy?
No. It is inserted only between adjacent copies.
How do I put each copy on a new line?
Press Enter once in the separator field to enter a real line break.
Does the tool preserve multiline source text?
Yes. Every source character is copied exactly, including its existing line breaks.
Is repeated text uploaded?
No. Repetition, previewing, and TXT download creation happen locally.
