Preset

Optimize for AI & RAG

Extra cleanup for LLM ingestion: strip HTML, fix smart quotes, tidy Unicode and spacing.

Add YAML front matter

Prepend a metadata block (title, source, date, word & token counts) for knowledge bases and RAG.

Add table of contents

Build a linked index from the headings. Handy for long documents.

Export RAG chunks (.json)

Split the result into retrieval-ready chunks. Download per file from the result panel.

02Why MarkdownPrivate Markdown

The format your
tools prefer.

Markdown is plain text with a few light marks. That simplicity is exactly what makes it the cleanest input for AI tools and the easiest format to keep, search and reuse.

A little markup, nothing locked in

Markdown adds meaning with a handful of characters: # for a heading, - for a list, ** for bold. The file stays readable as plain text, yet renders as a clean document anywhere. No proprietary container, no hidden styling, just the content and its structure.

What Markdown gives you.

Fewer tokens, lower cost

The same content carries far less markup than HTML or a PDF text dump. More of your document fits in a single prompt, and every call spends fewer tokens.

# Spec

- Auth flow

read as structure

Models read it directly

Language models are trained on Markdown, so headings, lists and code arrive as structure they understand, not noise to untangle.

Intro

Setup

Usage

Clean to chunk for RAG

Its heading hierarchy gives a retrieval pipeline natural cut points, so text splits into coherent chunks instead of arbitrary fragments.

Portable and future proof

Plain text opens in any editor, diffs cleanly in git and stays readable for decades. Nothing is trapped in one app or one file version.

03How it worksPrivate Markdown

Three steps,
start to finish.

No learning curve and no waiting around. From file to Markdown in about the time it took to read this.

DOCXreport.docx

Step 01

Drop your file

Drag it in, choose it, or paste it. One file or a whole pile, +135 formats, no setup.

Converting...local

Step 02

Convert in a click

Hit convert on a single file or the entire batch, follow the live progress, and cancel any time.

Step 03

Take your Markdown

Download a clean .md file or copy it straight to your clipboard. Batch them and zip the lot.

04Under the hoodPrivate Markdown

Your computer
does the work.

There's no cloud and no magic. The entire converter loads once, then runs inside your browser, using your own processor and memory, exactly like an app installed on your device.

Engine

The whole converter is code (JavaScript & WebAssembly) that loads once with the page and then runs inside your browser tab.

Speed & size

Bounded by your own CPU and RAM, just like any app on your computer. A faster machine handles bigger files, sooner.

Network

None required. Once the page has loaded you can switch off your internet and it keeps converting.

Loading

Each format's converter downloads only the moment you use it, so the page itself stays light and fast.

In plain terms: a faster computer with more memory converts bigger files, quicker. A phone works too, just with less headroom.

Most converters quietly upload your documents to a server. This one physically can't.

05PrivacyPrivate Markdown

Your files stay
yours.

Confidential contracts, financial sheets, personal notes: they're processed on your device and nowhere else. There is no upload step to trust, because there is no upload step.

Nothing leaves your device

Your file is read and converted inside the page. It never reaches a server, ours or anyone else's.

Nothing is kept

Files live only while the tab is open. Close it and there's nothing left behind: no history, no cache, no copies.

No accounts

No sign-up and no login. The files you convert are never tracked or stored.

NetworkLocal only

No file uploads

Not a mockup of a promise. Open your own browser's network tab while you convert: your document is never uploaded.

07LimitationsPrivate Markdown

Honest about
the limits.

Everything runs inside your browser. There is no server doing the work behind the scenes. That single choice is what makes the tool completely private, and it's also why a few things some converters do are simply off the table here. It's a trade, and we'd rather be upfront about it.
