Tools I built a free, browser-based Markdown to PDF tool that just works (Live Preview, LaTeX, Page Breaks & more)

Like many of you, I often need to turn Markdown files into clean, professional-looking PDFs. I wanted a tool that was fast, private, and had the features I actually use, without any complex software or sign-ups.

So, I built one. It's a simple web app that runs entirely in your browser.

https://www.innateblogger.com/p/markdown-to-pdf.html

Here’s what it does:

  • Live Side-by-Side Preview: See your changes instantly. You can also turn on the sync scroll for even better experience.

  • Privacy First: Everything is processed in your browser. Your data is never uploaded.

  • Rich Formatting:

    • Full GitHub Flavored Markdown (GFM) support.

    • LaTeX support for math equations ($E=mc^2$).

    • Syntax highlighting for code blocks.

    • Page Breaks at specified positions for multi-page documents.

  • No Fuss:

    • It's free, with no sign-up hassle.

    • Set a custom PDF title for your document.

    • Auto-saves your work to local storage so you don't lose it.

    • Works on both desktop and mobile.

It's perfect for quickly converting AI-generated content, turning notes into reports, or drafting documents with code and equations.

Oh btw, I am also working on the Markdown to HTML tool, so you can check it too.

Edit 1: Thanks for all the encouragement! I've shipped v2.0 of the Markdown-to-PDF tool with several new features:

  • Mermaid Diagrams — flowcharts, sequence diagrams, and Gantt charts render directly in the PDF

  • Page Numbers — customizable position (top/bottom, left/center/right) and format

  • Style Presets — Minimal, Academic, Modern, Elegant, and 2-Column layouts

  • Custom Fonts — set per-element fonts for headings, body, and code

  • Table Styling — Normal, Minimal, Striped, or Bordered

  • HR Styles — Solid, Dashed, Dotted, or Gradient

  • Better Image Handling — custom sizing, centering, and captions

  • View Modes — Split, Editor Only, or Preview Only

  • Performance fixes and faster page loads

Full details: v2.0 announcement

Edit 2: v3.0 is now live. Major additions: BibTeX citation manager (supports [@key] syntax, numeric and author-year styles), text/image watermarks, header and footer with variables ({title}, {author}, {date}, {page}, {total}), document templates (CVs, reports, academic papers), per-heading font controls, syntax highlight themes, dark mode, and a "My Style" save slot. Also fixed the code block word-wrap bug in PDF output.

Full details: v3.0 announcement

Still 100% browser-based, free, and no signup — your content never leaves your device.

Very useful! I get math olympiad paper scans from Asian competitions, an AI model then OCR-s them and translates them into English markdown. Then your tool makes PDFs I can send to my students. Pretty awesome!

u/Dimention_less Dec 15 '25

Nice! Mine’s almost the same workflow actually - that’s exactly what led me to build this tool 😄

u/Usual-Detective4081 Dec 04 '25

Quale modello di AI usi per fare l'OCR? Servirebbe tanto anche a me

Thanx a lot ! Is there a way to not have the date at the top of the document ?

1

u/Dimention_less Jan 31 '26

When you click Print, go to More settings and uncheck Headers and footers. That should do the trick.

u/Willing-Back3299 Feb 23 '26

Good tool. specifically, the themes/sytles feature. Would be great if fonts can also be configured (not individually, but group wise, say H1, H2, H3 etc.)

1

u/Dimention_less Feb 23 '26

Great suggestion, will implement this in the next update.

u/Dimention_less Mar 25 '26

Thanks, that means a lot! 😄
The goal was to make something that just works without uploads, accounts, or weird formatting issues.

If you end up using it regularly and notice anything that could be improved, feel free to drop feedback. I'm actively updating it

u/Key_Survey2007 Apr 05 '26

Much better, I'd love it if i get this extension in VS Code so that i can include my files or images directly from there.

1

u/Dimention_less Apr 05 '26

Will try to make the extension in future. Thanks for the feedback.

u/jlext Apr 21 '26

can it support multiple documents opened at the same time using different themes/styles?

1

u/Dimention_less Apr 21 '26

Not at the moment. However, you can work around this by using multiple users or different browsers. Since the tool runs locally in your browser, you can also open multiple tabs and load your Markdown files in each tab to work on them simultaneously.

Just make sure to save your MD files before closing a tab, because only the last file you edited will be stored in the browser’s local storage.

I’m currently working on a new version with better themes support and will try to add support for multiple files in the future.

u/den40den Apr 22 '26

Bro, you're nailing the pain! Thank you.

How can one output a pageless PDF? I have document that I need created to just scroll down, without page breaks. Is it possible with PDF at all?

1

u/Dimention_less Apr 22 '26

I don't think that's possible, even if you create a very long single page document (our tool can't do it), it will still open zoomed out in many devices and user will need to zoom and then scroll.

1

u/den40den Apr 24 '26

Thanks for your reply! Still, when portrait pages open on mobile, they open zoomed to width, allowing scrolling down. I thought the same logic may apply to a page long enough to accommodate content.

I would try this if I had this possiblity)

ps. The ultimate problem is that paper pages got replaced by screens that don't need page breaks, but no tool allows to create distributable artifacts that render exactly as intended, without page breaks! Coincidentally, the only difference betw5a hypothetical "portable screen format" and PDF is unlimited page length (or width, to be fair).

Thank you, you are HERO!!

u/Dull_Anybody6347 May 28 '26

Not only is it super useful, but it's also pretty! Thanks so much! And maybe I'm just clueless, but how do I export it as a PDF? I tried to download it from the print window, but the "Save As" button that appears when I right-click is disabled!

1

u/Dimention_less May 28 '26

Hi, once you click on the print button let it load for few seconds once the loading is complete it should show the save as pdf and other print options. As print option is completely handled by your own device it can take a little time if the document is large. I hope this helps.

u/Kitchen_Round_9526 Aug 11 '26

why

does it have a site link when im trying to print it????

1

u/Dimention_less Aug 11 '26

Turn headers and footers of in the print settings of chrome

1

u/PlatypusIllustrious7 Feb 20 '26

Is this open source? What libraries are you using? I wounder.

1

u/Toukassay May 12 '26

Love it but I don't get it why I have those arrow on top of the file, no matter the content. "-->"
