How to convert IPYNB to HTML
Jupyter Notebook files (.ipynb) are JSON documents that combine code cells, markdown text, and cell output including tables, charts, and images. The problem with sharing .ipynb files is that recipients need a Jupyter environment to open them. Converting a notebook to HTML produces a static page that renders in any browser, preserving code, output, and explanatory text with no installation required.
BoltConverter converts your notebook on our servers using nbconvert-compatible rendering. The output HTML includes all cell types: code cells, markdown, and rich output such as DataFrames and Matplotlib charts. After conversion, both files are deleted from the server immediately.

Notebook is rendered to HTML
BoltConverter processes the notebook JSON, renders markdown to HTML, syntax-highlights code cells, and includes all stored cell outputs.

Frequently asked questions
Does the HTML include charts and table outputs?
Yes. Any output stored in the notebook at the time of export is included in the HTML. This includes pandas DataFrames rendered as tables, Matplotlib figures saved as inline images, and printed text output.
Does the HTML file execute code?
No. The HTML is a static rendering of the notebook as it was last run. Code cells are displayed with syntax highlighting but are not interactive or executable.
Will the HTML work without internet access?
The HTML file is self-contained. Code highlighting CSS may require internet access depending on how the file is rendered. For fully offline viewing, the standard output works best when opened in a modern browser.
What if my notebook has not been run and has no cell outputs?
If cells have no stored output, only the code and markdown content will appear in the HTML. Run your notebook first if you want the outputs to be visible in the export.
Are my notebook files stored on the server?
No. Both the uploaded .ipynb file and the resulting HTML are deleted from our servers immediately after you download the result.
