About tomdnow

Our Story

tomdnow was created by Park Gamsa, a developer based in South Korea, to solve a simple but persistent problem: converting files to Markdown shouldn't require sign-ups, subscriptions, or trusting a third party with your data.

What started as a personal tool for converting Korean government documents (HWP/HWPX) into Markdown for AI processing quickly grew into a full-featured converter supporting 20+ file formats.

Today, tomdnow processes thousands of conversions daily across 8 languages, serving developers, researchers, students, and knowledge workers who need their documents in Markdown for tools like Obsidian, Notion, GitHub, and AI systems like ChatGPT and Claude.

How It Works

tomdnow is powered by Microsoft's open-source MarkItDown engine, which means your conversions benefit from enterprise-grade parsing without the enterprise price tag.

Every file is processed entirely in memory. Nothing is written to disk, nothing is stored in a database, and nothing persists after your browser tab closes. The conversion happens, you get your Markdown, and the data is gone.

The tool supports 20+ file formats including office documents (PDF, DOCX, XLSX, PPTX), Korean documents (HWP, HWPX), data formats (CSV, JSON, XML), ebooks (EPUB), email archives (MSG), image OCR, YouTube transcripts, and ZIP archives containing any supported format.

Privacy by Design

We believe privacy isn't a feature — it's a foundation. tomdnow was built from day one with a zero-storage architecture. Your files never touch a permanent storage layer.

All transfers are encrypted with TLS 1.3, and the conversion backend runs in isolated containers that are recycled regularly.

We deliberately chose not to implement user accounts, analytics cookies, or file upload logging. The only data we collect is anonymous usage metrics through privacy-respecting analytics. Your documents remain yours — always.

Our Mission

Markdown is the universal language of documentation, note-taking, and AI. We want to make it effortless to get any document into Markdown — whether you're a developer, researcher, student, or office worker.

tomdnow will always have a free tier. We believe essential document conversion should be accessible to everyone.
