Convert Markdown to PDF

No — this conversion pins the layout. A Markdown adapts its line breaks to whatever width and font size the reader is using; the PDF fixes page geometry at conversion time, so on a phone you get the whole page scaled down rather than text rewrapped to the screen. That is the right trade when the layout must not move, and the wrong one when the file is for reading on a small device. The long form is what Jekyll, Hugo and several documentation pipelines look for by default, so it fits straight into those builds. PDF is Adobe’s Portable Document Format from 1993, standardised as ISO 32000 and now the universal fixed-layout document.

It will look plain, because there is nothing to recover. A Markdown carries no styling information, so the converter applies a clean default — a readable body font, sensible margins, paragraphs separated where blank lines were. Headings are inferred where the source used a recognisable convention, and everything else arrives as body text. Markdown is the same syntax as .md, spelled out in full — some editors and static site generators expect the long extension.

Not the way you edit the Markdown. The PDF is a delivery format: it fixes the layout so it renders identically everywhere, which is exactly why it resists editing. Keep the Markdown as the working copy and regenerate the PDF whenever the content changes — round-tripping back out of PDF always loses something.

CommonMark plus the GitHub Flavored Markdown extensions, which is the combination almost every current tool understands. That matters because Markdown was never standardised in one place: tables, footnotes, strikethrough and raw HTML behave differently between dialects, and those are exactly the constructs that silently change meaning when a document moves between renderers.

Yes for text-bearing Markdown (DOCX, ODT, HTML, TXT) — fonts are embedded into the PDF so the output looks identical on every viewer. Image-only Markdown (JPG, PNG) just centers the image on the page; layout is N/A.

Yes — drop multiple Markdown files into the upload zone and choose the "merge into one PDF" option. They appear as sequential pages in the PDF in upload order; drag-to-reorder is supported before conversion.

Defaults: A4 portrait (international) or letter portrait (US). The advanced options expose page-size (A3, A4, A5, letter, legal, tabloid, custom) and orientation (portrait / landscape). For image Markdown, "auto-fit" picks orientation to match the source aspect ratio.

Yes for Markdown formats that have real hyperlink metadata (DOCX, ODT, HTML). Image-based Markdown (JPG, PNG, TIFF) have no hyperlinks to preserve. The PDF file uses standard PDF URL actions so links work in every PDF reader.

Yes when the Markdown contains real text (DOCX, ODT, HTML, TXT). Image-based Markdown produces an image-only PDF — to make it searchable, use /pdf-ocr/ after conversion to run optical character recognition.

Not in this tool — convert Markdown to PDF first, then use /pdf-protect/ to add a password, watermark, or restrict editing. Splitting the operations makes it easy to reconvert without re-typing the password.

Depends on the Markdown. A 10-page DOCX with embedded fonts produces a 200-400 KB PDF. A 10-image JPG batch at full resolution produces a 5-20 MB PDF. The advanced options expose a "compress images in PDF" toggle that recompresses embedded images at JPG quality 85.
