IPYNB to BMP2 Converter
FileFlip converts IPYNB to BMP2 entirely inside your browser, using Pandoc, MuPDF and ImageMagick compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an IPYNB file to BMP2?#
- Drop your IPYNB file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to BMP2 and the conversion starts on its own. FileFlip downloads 79.9 MB of WebAssembly the first time and nothing after that, then runs Pandoc, MuPDF and ImageMagick on your own machine.
- Save the BMP2 file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting IPYNB to BMP2 lose quality?#
Yes, in the sense that text stops being text. Each IPYNB page is rendered to pixels and handed to BMP2, so the result looks right and can no longer be selected, searched, or reflowed.
Is it safe to convert IPYNB files online?#
Yes, because nothing is uploaded. FileFlip converts IPYNB files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What IPYNB to BMP2 actually does to the file#
Converting IPYNB to BMP2 runs on Pandoc, MuPDF and ImageMagick, downloads 79.9 MB of WebAssembly the first time and nothing after that, renders each page to pixels, keeps page layout, and drops selectable text and transparency.
| Engine | Pandoc, MuPDF and ImageMagick |
|---|---|
| Conversion path | 3 steps: IPYNB → HTML → PNG → BMP2 |
| Downloaded to your browser | 79.9 MB, once, then cached by your browser |
| Quality | Text becomes pixels |
| You get back | One image per page, zipped when the source has several |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| Selectable text | Dropped | The target format has nowhere to put it. |
| Page layout | Kept | Carried through into the converted file. |
| Transparency | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- pages render at twice their point size in opaque RGB, roughly 144 DPI, with no transparency
- reflowable input is laid out on a fixed 595x842pt page at 11pt before anything else happens
- the file passes through HTML on the way, so anything HTML cannot express does not survive
What is an IPYNB file?#
An IPYNB file is a Jupyter notebook: a JSON document that interleaves markdown text and code cells with the stored output of each cell's last run, including rendered plots and printed results.
Keep a document as IPYNB while it needs to stay runnable, meaning someone will re-execute the code and expect fresh output.
Convert IPYNB to another format when sharing the result with someone who only needs to read it, such as a report, a slide deck, or a PDF.
What is a BMP2 file?#
BMP2 is ImageMagick's name for a Windows bitmap saved with the original 12-byte BITMAPCOREHEADER from 1987's OS/2 1.x, an encoding choice rather than a different file format, so the result is an ordinary uncompressed .bmp using the oldest and most limited header structure.
Choose BMP2 only when a specific legacy OS/2 or early-1990s Windows program requires the old-style bitmap header.
Save as standard BMP or BMP3 for anything opened on a modern system, since BMP2's extra compatibility buys nothing there.
IPYNB to BMP2 questions people ask#
What is an IPYNB file?
An IPYNB file is a Jupyter notebook, a JSON document made of code cells, text cells, and the output each code cell produced the last time it ran, including any charts or printed results. The name comes from IPython, the project Jupyter grew out of.
Can I open an IPYNB file without installing Jupyter?
Yes. GitHub renders .ipynb files directly in the browser, Google Colab opens and runs them with no local install, and Visual Studio Code opens them with its Jupyter extension. Installing JupyterLab or Jupyter Notebook is only needed to run the code locally.
What happens to the code when I convert a notebook to PDF or Word?
Converting an IPYNB file to PDF, Word, or HTML flattens it into static text and images: the code appears as a formatted listing and the stored outputs appear as rendered results, but neither can be executed or edited afterward. The notebook stops being a runnable program and becomes a fixed report.
Why does my notebook's git diff show changes when I didn't edit any code?
Running a Jupyter notebook updates its execution_count numbers and the stored output for every cell, and both are written into the same JSON file as the code. Git sees those as changed lines even when the actual code is untouched, which is why notebook diffs are noisy compared to plain source files.
