How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a Kindle Clippings from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your Markdown the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Open source, every line of conversion code is public.

About Kindle Clippings and Markdown

Kindle Clippings, Kindle My Clippings.txt

My Clippings.txt is the file every Kindle device maintains internally, a plain-text log of every highlight, note, and bookmark you've made across all your books. Plug your Kindle into a computer via USB and it appears in /documents/My Clippings.txt. The format is line-based with == separators; great for archiving your reading history into Notion, Obsidian, Readwise, or any markdown system.

How to open

Plain text, open in any text editor. The file is machine-readable, which is why people convert it into structured formats (CSV, Markdown, Notion-compatible CSV) for import into knowledge-management tools.

Markdown, Markdown

Markdown is plain text with simple punctuation conventions for formatting, # for headings, * for lists, ** for bold, links as [text](url). Created by John Gruber in 2004 and now the default for GitHub READMEs, documentation sites, and modern note-taking apps (Obsidian, Notion-export, Bear).

How to open

Any text editor (raw). Rendered: GitHub, GitLab, VS Code preview, Obsidian, Bear, Notion (importable), Typora, MarkText, Markdown Editor.

FAQ

Common questions

Is this Kindle Clippings → Markdown converter really free?

Yes. No signup, no watermark, no daily file count limit. The entire engine is open source, you can read the conversion code on GitHub.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert Kindle Clippings to Markdown?

Archiving Kindle highlights for personal knowledge management. Documentation, READMEs, notes, blog posts. The most common reason to convert is compatibility, Markdown works in places where Kindle Clippings doesn't, or vice versa.

How do I open a Kindle Clippings file in the first place?

Plain text, open in any text editor. The file is machine-readable, which is why people convert it into structured formats (CSV, Markdown, Notion-compatible CSV) for import into knowledge-management tools.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
