When plain text needs to become a PDF
Plain text is the most universal format there is, and also the least presentable. Notes taken in a browser tab, a message drafted in a text editor, a program’s log output, a list copied out of a database — all of it is fine on screen and awkward to send to anyone.
Converting to PDF fixes four things at once. The layout becomes fixed, so line breaks no longer depend on the reader’s window width. You gain a title, page numbers and consistent margins. The file gains a page count, which matters for printing and for official submissions. And the recipient cannot accidentally delete a line while reading it.
Common real cases: printing a leave application or a rent receipt, submitting a typed declaration to a portal that only accepts PDF, turning a CS project’s output log into an appendix, and archiving chat messages or notes as a fixed document.
Layout controls that matter more than they sound
Line spacing is the single biggest readability win. At 100% the lines almost touch; 140% is the pleasant default for a letter; 160–180% suits dense text that will be read on screen. For documents a reviewer will annotate by hand, go higher still.
Font choice carries meaning. Helvetica is neutral and modern, which suits notices, reports and technical documents. Times Roman reads as formal and slightly old-fashioned, which is exactly right for official letters and anything addressed to a government department. Courier is fixed width, so columns of numbers line up — the right choice for code and tabular logs.
Margins are practical, not decorative. A 20 mm margin looks balanced on A4. If the document will be hole-punched or bound, 25–30 mm on the binding side avoids losing text. If it will be pasted into another document, wider margins make it easier to cut.
Justified text straightens the right edge, which looks tidier for paragraphs. It can create stretched gaps in narrow columns, so it is worth trying both ways on a short sample before committing.
An honest note about languages and special characters
The built-in PDF fonts used here are the standard fourteen that every PDF reader is guaranteed to have. They cover English and most Latin-script European languages, including accented characters such as é, ü, ç and ñ, and common punctuation like em dashes and curly quotes, which are converted automatically.
They do not cover Devanagari, Tamil, Bengali, Arabic, Chinese, Japanese, Korean or Cyrillic. If you paste Hindi or Tamil text, those characters are replaced with a question mark, and the tool warns you clearly so you are not surprised by the result.
For Indian language documents there is a better route on this site: use the HTML to PDF tool, which lays out text through a different engine that handles a wider range of scripts, or use your operating system’s own print-to-PDF with a font that supports the script. We would rather tell you this plainly than produce a document you cannot read.
A practical workflow for long text
For anything longer than a page, a small amount of preparation saves a lot of fiddling. Put a descriptive title in the heading field — recruiters and clerks read file names and headings first, and a document that says “Leave application, October 2026” is easier to file than “Untitled”.
Keep one blank line between paragraphs rather than using indentation; blank lines survive the conversion to every font and size combination predictably. If your source text has hard line breaks in the middle of paragraphs, the tool can be set to treat each line as its own paragraph — which is usually what you want for lists and code, and usually not what you want for prose.
Finally, turn on page numbers. Any document longer than two pages will be printed and dropped at some point, and a page without a number is a page that can be lost in the wrong order.
