BibTeX to ICON Converter
FileFlip converts BibTeX to ICON 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 a BibTeX file to ICON?#
- Drop your BibTeX 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 ICON 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 ICON file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting BibTeX to ICON lose quality?#
Yes, in the sense that text stops being text. Each BibTeX page is rendered to pixels and handed to ICON, so the result looks right and can no longer be selected, searched, or reflowed.
Is it safe to convert BibTeX files online?#
Yes, because nothing is uploaded. FileFlip converts BibTeX 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 BibTeX to ICON actually does to the file#
Converting BibTeX to ICON 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: BibTeX → HTML → PNG → ICON |
| 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 a BibTeX file?#
A BIB file is a BibTeX bibliography database, plain text listing typed reference entries such as @article and @book that the bibtex program formats into a document's citations and reference list.
Keep a bibliography as BibTeX when it's cited from a LaTeX document, since bibtex and biblatex read the format natively.
Convert BibTeX to RIS when moving citations into a reference manager or database that doesn't read BibTeX directly.
What is an ICON file?#
ICON is ImageMagick's alternate name for the ICO format, the container Windows uses for small multi-resolution images shown as application, file and shortcut icons, so a file written as ICON is the same Windows icon container as one written as ICO.
Use ICON, or the equivalent ICO, for Windows application icons, favicons and shortcut images, where the file needs to offer several sizes in one container.
Convert to PNG when a single-resolution image is needed for general use, since most software outside Windows icon contexts doesn't expect an ICO/ICON container.
BibTeX to ICON questions people ask#
What program opens a .bib file?
A .bib file is plain text, so it opens in any editor, but reference managers like JabRef, Zotero and Mendeley open it as a structured bibliography with fields for author, title and year rather than raw text.
What's the difference between BibTeX and RIS?
BibTeX is the citation format LaTeX documents cite against, with entries typed as @article or @book. RIS is a tagged format built for reference manager interoperability rather than any one typesetting system. Most reference managers convert between the two on import and export.
Can I edit a .bib file in a plain text editor?
Yes. A BibTeX file is human-readable text, and each entry's fields, author, title, year, journal, are plain key-value pairs, so editing one directly is common and doesn't require special software.
What's the difference between BibTeX and BibLaTeX?
BibTeX is the original 1985 citation processor and its .bib file format. BibLaTeX is a newer LaTeX package that reads the same .bib files but does the citation formatting inside LaTeX itself, usually paired with the biber backend instead of bibtex, which handles Unicode and more fields correctly.
