TXT Converter
FileFlip converts TXT files into 61 other formats entirely inside your browser, using MuPDF, ImageMagick and Pandoc compiled to WebAssembly. The TXT file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert a TXT file?#
- Drop your TXT file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert TXT files online?#
Yes, because nothing is uploaded. FileFlip converts TXT 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 is a TXT file?#
A TXT file is a sequence of characters and line breaks with no formatting, container or metadata at all, so the only two things that determine whether it opens correctly on another machine are its character encoding and its line-ending convention.
Use TXT for anything a script, a diff tool or a command line will read, or when the destination genuinely needs the words with no formatting attached.
Convert TXT to DOCX or PDF when the plain words need headings, styling or a fixed page layout added on top of them.
The TXT file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
TXT questions people ask#
Why do accented characters turn into strange symbols when I open a TXT file?
A TXT file has no way to declare its own character encoding, so the program opening it has to guess. When a file saved as UTF-8 gets opened as a legacy encoding like Windows-1252 instead, multi-byte characters like é or emoji get reinterpreted as several unrelated symbols, a corruption usually called mojibake.
Why does a TXT file made on Windows show as one giant line on Mac or Linux?
Windows ends each line with two characters, carriage return and line feed (CRLF), while Unix, Linux and modern macOS use just a line feed (LF). A program that only recognizes LF as a line break sees a CRLF file's carriage returns as ordinary characters, so the whole file can appear as one unbroken line until it's reopened with the correct convention.
What is a byte order mark and why does it show up at the start of a TXT file?
A byte order mark, or BOM, is an invisible marker some Windows tools add to the start of a UTF-8 TXT file to flag its encoding. Software that doesn't expect it can render it as stray characters like  at the very start of the text, or count it as part of the first line of content.
Is a TXT file the same on every operating system?
The characters themselves are, but a TXT file's encoding and line endings follow different conventions by platform, and those are exactly what break when the file moves between them. A file that looks fine where it was created can show garbled accents or mangled line breaks the moment it's opened somewhere else.
