Stackbench Markdown Viewer & Exporter
Write or open Markdown and see it rendered exactly as it will be saved. Choose a theme (GitHub, Dracula, Nord, Solarized and more), a size from phone width to A4 pages or a 16:9 slide, set the page margin, then export to the format you need — all inside your browser.
Nothing to preview yet — type some Markdown on the left.
How to use
- Type or paste Markdown on the left, press Open .md file, or drop a file onto the box; Load sample fills it with a report that uses headings, lists, a table and code.
- Pick a theme, font and font size, then choose a Page size: a fit-content width, a fixed page such as A4, Letter, square or social card, or a custom width and height.
- Set the page margin, the space between the text and the edge of the page. The preview updates as you change it, and dashed lines mark page breaks on fixed-height sizes.
- Choose a format (PNG, JPG, WebP, SVG, PDF, HTML or the Markdown source), set the pixel density, then press Export — or Copy as image to paste the first page straight into a chat or document.
Frequently asked questions
Is my Markdown uploaded anywhere?
No. Parsing, layout and export all run in this page. The only network requests are ones you ask for yourself, such as an image link inside your Markdown that the page fetches so it can be embedded in the export.
What happens when the text is longer than the page size I picked?
On a fit-content size the image simply grows taller. On a fixed size such as A4 or 1080 × 1080 the content continues onto further pages: images are saved as numbered files, a PDF gets one page each, and the preview marks every break. If you would rather have one tall picture, switch to a fit-content size or a custom height of 0.
Why is an image in my Markdown shown as a dashed label?
To save a picture or SVG, the browser must embed every image, and it can only read a remote image if that site allows cross-origin access. Images that do not are shown as labelled placeholders instead of silently missing. Use a data: URL, or host the image somewhere that allows CORS. Raw HTML in the Markdown is shown as text rather than executed, so exports are safe to share.
