MakeItMarkdown vs online converter sites
Search "docx to markdown online" and you'll find pages with an upload button. They mostly work. The comparison isn't about whether they convert — it's about what "upload" means, and about what kind of Markdown comes back.
1 · Where your file goes
An upload-based converter, by architecture, receives your document on its servers, converts it there, and serves the result back. That's not an accusation of bad faith — it's just what the design requires. The consequences are structural:
- Your file transits and lands on infrastructure you don't control, under a privacy policy you probably didn't read.
- Retention is whatever they say it is (often "deleted after N hours"), and unverifiable either way.
- Confidential material — unpublished work, client documents, internal reports — acquires a copy outside your perimeter.
MakeItMarkdown's architecture makes the opposite claim, and makes it checkable: conversion is JavaScript running in your browser. Load the page once, disconnect from the internet, convert — it works, because no server was ever part of the loop. Your browser's network tab shows the same story during any conversion. (Full policy: privacy.)

site. Muted, loopable.2 · What kind of Markdown comes back
Generic converters aim at "a valid .md file". Feeding a model raises the bar in specific ways:
| Typical uploader site | MakeItMarkdown | |
|---|---|---|
| Loss reporting | None — silent | Fidelity report: detected counts, warnings, weighted QC score |
| Tables | Converted if easy | Typed headers, explicit truncation, ragged-row repair |
| Embedded images | Often inline base64 | Extracted files + [Figure: …] placeholders |
| Notebooks | Rarely supported | Cell addresses, dependency hints, order warnings |
| Output targets | One .md | Chat / RAG / Obsidian / Archive presets |
| Cost model | Free tier + size/paywall upsells | Static site; no accounts, no caps |
3 · When an uploader site is fine
Public documents, no confidentiality stakes, a format we don't cover yet — use whatever works. The architecture argument matters in proportion to what's in the file.
Test the claim the blunt way: load this site, turn off your Wi-Fi, and convert a file.
