Marklet · Markdown viewer for macOS
Open Markdown. Just read.
Marklet is a native, read-only viewer for local Markdown and text files. Drop in a document, get GitHub-style rendering, and keep the original file untouched.
Read-onlyNo editing, creation, or content management. Marklet only renders files you open.
LocalNo account, sign-in, analytics, ads, SDKs, or uploads.
NativeBuilt for macOS workflows: Finder, Open Recent, printing, and PDF export.
Safe by defaultRemote images are blocked unless you enable them per document.
The viewer
A focused Markdown surface with no editor hiding inside.
02 / Render
GitHub-style formatting.
Headings, tables, code blocks, links, and local images render in a familiar reading layout. The source document remains unchanged on disk.
03 / Read
Small conveniences, considered.
Find in page with Command-F, adjust text zoom, reload live when the file changes on disk, print the rendered document, or export it to paginated PDF in A4 or Letter.
Security model
Designed for local documents and quiet defaults.
Nothing is collected.
Marklet has no analytics, ads, third-party SDKs, account system, or sync service. Stored state is limited to ordinary user defaults and macOS recent-document bookmarks.
Remote content is off.
The app makes no network requests by default. Remote images are blocked at render time, by Content Security Policy, and by the navigation delegate unless you enable Load Remote Images for the current document.
Sandboxed and read-only.
Local resources are served through a restricted mdres:// scheme for the document folder. Path traversal, symlink escapes, javascript:, data:, and file: URLs are rejected or stripped.
How to test
No account. No server. Any Markdown file works.
Launch Marklet.
Open the app and drop a .md file onto the welcome window, or choose Open File from the standard macOS panel.
Exercise rendering.
Use a Markdown file with headings, a table, and a code block to verify the GitHub-style renderer.
Export a PDF.
Choose File, Export as PDF or press Command-E to create a paginated A4 or Letter PDF.
Marklet · for macOS
A Markdown viewer that stays in its lane.
Use Marklet when you want to inspect, present, print, or export a Markdown file without opening a full editor or handing the document to a web service.
