txt2tags to ICON Converter
FileFlip converts txt2tags 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 txt2tags file to ICON?#
- Drop your txt2tags 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 txt2tags to ICON lose quality?#
Yes, in the sense that text stops being text. Each txt2tags 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 txt2tags files online?#
Yes, because nothing is uploaded. FileFlip converts txt2tags 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 txt2tags to ICON actually does to the file#
Converting txt2tags 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: txt2tags → 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 txt2tags file?#
A T2T file holds txt2tags source, Aurelio Jargas' 2001 lightweight markup that its own command-line tool compiles into HTML, LaTeX, MediaWiki, DokuWiki and a dozen other target formats from one source file.
Use txt2tags for a document that needs to compile to several very different output formats from one plain-text source.
Convert a T2T file to Markdown when the txt2tags tool itself is no longer part of the workflow.
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.
txt2tags to ICON questions people ask#
What is a T2T file?
A T2T file holds txt2tags source, a lightweight plain-text markup created by Aurelio Jargas in 2001. It's meant to be compiled, not opened directly, since the txt2tags command-line tool turns one .t2t file into whichever output format the document actually needs.
What formats can txt2tags convert to?
txt2tags compiles a single .t2t source file to HTML, LaTeX, MediaWiki, DokuWiki, man pages, and several other targets, which is the whole point of the format: write once, generate whichever output a given publishing destination needs.
Is txt2tags still maintained?
Yes, though slowly. txt2tags reached version 3.9 in October 2023 under maintainer Jendrik Seipp, well over two decades after Aurelio Jargas' original 2001 release, and the format itself has changed very little in that time.
What is the difference between ICON and ICO?
There isn't one. ICON is ImageMagick's alternate name for its ICO coder, so a file written as ICON is the same Windows icon container as one written as ICO.
