TXT to PDF
Convert plain-text files (.txt) into a PDF document with real, selectable, searchable text — not images. Choose Sans, Serif, or Mono fonts. Files are processed in your browser.
TXT to PDF converts plain-text files into a PDF document with selectable, searchable text rendered using pdf-lib's drawText API in a Web Worker. Pick from three built-in fonts — Helvetica (Sans), Times-Roman (Serif), or Courier (Mono) — choose page size and margin, and the resulting PDF preserves your text as actual text, not images. Code, logs, configs, and notes stay readable, indexable, and copy-pasteable in any PDF reader.
What is TXT to PDF?
Plain text — files with the .txt extension — is the lowest-common-denominator file format. No formatting, no styles, no embedded images: just characters. That makes it the universal interchange format for source code, configuration files, server logs, terminal output, console captures, README notes, ASCII art, and anything else you want to read forty years from now without worrying about whether the application that created it still exists. Every operating system since the early 1970s reads .txt files.
Converting TXT to PDF is usually about distribution and presentation: emailing a log file as a paginated document, attaching a server output to a ticket without forcing the recipient to open a text editor, archiving a chat transcript with proper page numbers, or producing a printable handout from a code listing. Most online TXT-to-PDF converters upload your file to a remote server. This tool runs the conversion entirely in your browser, and unlike screenshot-based converters, the text stays as text in the PDF.
How does the in-browser TXT conversion work?
Pikowl reads each text file via the Blob.text() API, then sends the content to a Web Worker. The worker uses pdf-lib's drawText primitive — backed by the PDF spec's native text-drawing model — with one of the Standard PDF fonts (Helvetica, Times-Roman, or Courier). The worker handles word wrap to your chosen margin width and paginates content across pages. The resulting PDF has selectable, searchable text — Cmd+F finds words, copy-paste returns characters, screen readers parse the content. Nothing is sent to any server.
Is it safe to convert sensitive text files here?
Yes. Open the network tab in DevTools while you use the tool — you will see no outbound requests during the conversion. Text files are read locally via the File API, processed in a sandboxed Web Worker, and the resulting PDF lives only in your browser's memory until you download it. Server logs containing IP addresses, .env files containing secrets, and internal documentation never cross the network.
What about character encoding and Unicode?
The Standard PDF fonts (Helvetica, Times-Roman, Courier) use WinAnsi encoding — they support the Latin-1 character set (English, most Western European languages, basic punctuation, currency symbols) but do not include Cyrillic, Chinese/Japanese/Korean (CJK), Devanagari, Arabic, or emoji glyphs. Characters outside Latin-1 will render as missing-glyph boxes or be replaced. For non-Latin content, save your text as Markdown or HTML and use those tools, which embed full Unicode fonts via html2canvas — your characters will render correctly there.
What are the limits and why?
Up to 50 text files per conversion, 10 MB per file, with a soft warning at 100 MB combined and a hard cap at 150 MB. A 10 MB plain-text file is roughly 10 million characters — enough to hold the King James Bible five times over. Beyond this, paginating in-browser becomes impractical (a single 10 MB log file produces thousands of PDF pages); for larger files, split or grep first, then convert.

Common Uses
- Server logs and stack traces: Convert a multi-megabyte log capture into a paginated PDF for a support ticket — recipients can search and copy errors directly out of the PDF.
- Code listings: Print a function or module with proper monospace font for code review handouts or coursework submissions.
- Configuration file archives: Save .env templates, dotfiles, or YAML configs as PDFs for compliance audits or runbook attachments (without secrets).
- Chat and meeting transcripts: Convert exported chat logs or meeting transcripts into a paginated, page-numbered PDF for distribution.
- ASCII art archival: Preserve ASCII signatures, banners, or text-mode diagrams in monospace font with margins matched to the original layout.
- Notepad and Markdown drafts: Quick-export plain-text notes for sharing without forcing the recipient to open a text editor.
FAQ
Is the text in the PDF selectable and searchable?
Yes. We use pdf-lib's drawText primitive, which embeds your text as actual PDF text objects — Cmd+F finds words, copy-paste returns characters, screen readers parse the content correctly. This is fundamentally different from screenshot-based TXT converters that produce image-only PDFs where the text isn't accessible.
Will my Unicode characters (Chinese, emoji, accented letters) render correctly?
Latin-1 characters render correctly (English, French, German, Spanish, Italian, Portuguese, Polish, etc.). Cyrillic, Chinese, Japanese, Korean, Devanagari, Arabic, and emoji are NOT supported — pdf-lib's built-in fonts (Helvetica, Times-Roman, Courier) are WinAnsi-encoded. For non-Latin text, save your content as Markdown or HTML and use those tools, which embed full Unicode fonts via html2canvas rendering.
What happens to long lines without spaces (URLs, hashes)?
Long unbreakable strings are hard-broken at the line boundary. A 100-character SHA-256 hash will wrap at the page width edge instead of overflowing. This preserves readability of the surrounding content even at the cost of mid-string breaks.
Will indentation and whitespace be preserved?
Leading whitespace is preserved character-for-character. Tabs are converted to 4 spaces (the common convention for code listings). Multiple consecutive spaces inside lines are preserved. Trailing whitespace is dropped at line wrap.
How do I choose between Sans, Serif, and Mono?
Sans (Helvetica) is the default — clean, neutral, good for prose and notes. Serif (Times-Roman) suits longer reading material like essays or transcripts. Mono (Courier) is for code, logs, ASCII art, and any content where character alignment matters — every character is the same width.
Are text files uploaded to a server?
No. The conversion runs entirely in your browser — open DevTools' network tab and you'll see no outbound requests during the process. Text content is read from your disk via the File API, processed in a Web Worker using pdf-lib, and offered back as a download. Sensitive content like log files or configuration never leaves your device.
Why a 10 MB per-file limit?
10 MB of plain text is approximately 10 million characters — already enough to produce thousands of PDF pages. Beyond this, in-browser pagination becomes impractical and the output PDF can exceed memory limits on mobile devices. For very large logs or transcripts, grep or split the file first.
By the Numbers
- PDF was originally based on Adobe's PostScript page-description language (1985), and the text-drawing primitives we use here have been part of every PDF specification since the format's debut in 1993.
- pdf-lib's built-in Standard 14 fonts (Helvetica, Times-Roman, Courier and 11 variants) are mandatory in every PDF reader — they don't need embedding, which is why a 10-page TXT-to-PDF output is typically just 10-20 KB.
- Plain text remains the most durable file format in computing — files written with edlin on MS-DOS in 1981 still open identically in macOS TextEdit in 2026, which is why log files, source code, and configuration almost always default to .txt-style formats.
