Add padding on both sides of each line so shorter text occupies a chosen width in plain text. Follow the exact input and settings below to reproduce this example. Open Center Text.
Prepare the source text
Open Center Text and choose Write or paste text, or upload a supported UTF-8 text file. The upload opens the editor; it does not run the tool. This example uses the exact source shown in the comparison.
Maximum input and result: 1 MB of UTF-8 text, with a 1,048,576-character input ceiling. Expanding transformations must also fit the result limit.

Heading Note
This text operation runs in your browser; its source and result are not sent for conversion. A draft may be kept in this browser tab when session storage is available. Clear removes the current draft; download important work before closing the tab.
Choose the settings
For the recorded example, use these settings: Target line width: 12; Padding characters: One space.
Each line is measured separately. The missing width is divided between left and right padding; if an extra character is needed, it goes on the right. Multiple padding characters cycle in their entered order. Lines that already meet or exceed the target width are not shortened.

Apply and inspect the result
Select Center Text when the input and settings are ready. In the saved example, the result begins: "Heading ".
Plain-text alignment is most predictable in a monospaced font. Character counts do not guarantee equal visual widths for every language or font.
Result overview compares Target line width with the Longest line in the result and shows the input-to-result character totals. A longer source line can exceed the target because centering does not shorten it.
Result overview distinguishes changed, unchanged and empty results. An unchanged result means the selected operation did not alter the text; an empty result can be the expected outcome of removal or extraction. Open Show spaces and tabs to reveal spaces as ·, tabs as ⇥ and line endings as ↵. These marks are only a preview; copied and downloaded text keeps its actual whitespace. The whitespace preview shows at most 12,000 Unicode code points. This preview limit does not shorten the editable result or its TXT download.

Editing the result hides the calculated details until you run the tool again. Copy and TXT download use the edited text; return to the source and reapply the tool to refresh the report.
