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 Obsidian 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. Drop a file, get a converted file.

Why convert Kindle Clippings → Obsidian (.md)

What this conversion is actually for

Kindle's My Clippings.txt is one undifferentiated text dump for every book you've ever highlighted. Importing that as-is into Obsidian gives you a single 50,000-line note that's useless for review. Splitting clippings into one Markdown file per book, with frontmatter for author/title and clean blockquote formatting, turns your highlights into actual second-brain material you'll actually open.

A real example

You read 12 books on your Kindle this year. You plug it into your Mac, copy My Clippings.txt off the device (it's at the root), drop it here, and download a zip with twelve .md files. Each one drops cleanly into your Obsidian vault under Sources/Books/, ready for the [[wiki-style]] linking and tag system you already use.

Troubleshooting

Some highlights look duplicated.

Kindle records every highlight whenever you adjust its boundaries. The converter de-duplicates exact text matches but keeps slightly-different versions on purpose so you don't lose your final wording. Open the .md and delete the partial earlier versions if they're noisy.

Notes I wrote attached to a highlight are missing.

Older Kindle firmware (pre-5.13) stored notes as separate entries with no link back to the highlight they belong to. We attach them when the timestamps match within 60 seconds; otherwise they appear as standalone entries at the bottom of the book's note. If yours come out detached, your firmware predates the linking format.

My Clippings.txt isn't on my Kindle when I plug it in.

Newer Kindles (Scribe, Colorsoft, 11th gen Paperwhite) hide the documents folder by default. Enable USB drive mode in Settings → Device Options → Advanced. Older models show it instantly under Internal Storage / documents/.

About Kindle Clippings and Obsidian 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.

Obsidian Markdown, Obsidian-flavored Markdown

Standard Markdown with Obsidian-specific extensions, YAML frontmatter for metadata, [[wikilinks]] for cross-references, #tags for organization, ![[]] for embedded media. Drop into your Obsidian vault and the file is immediately searchable, linkable, and graph-visualizable.

How to open

Obsidian primarily. Renders fine as regular Markdown elsewhere, you just lose the wikilink magic.

FAQ

Common questions

Is this Kindle Clippings → Obsidian (.md) converter really free?

Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.

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 Obsidian Markdown?

Archiving Kindle highlights for personal knowledge management. Knowledge graphs in Obsidian. The most common reason to convert is compatibility, Obsidian Markdown works in places where Kindle Clippings doesn't, or vice versa.

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

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.
