How it works
Add your Plain text file. MimiFile checks the format, converts it to EPUB, and provides a temporary download when the result is ready.
Convert plain TXT into a reflowable EPUB when you need the text in an e-reader format rather than as a raw text file.
TXT → EPUB
Drag and drop, paste a file, or browse your device.
Files are temporary and deleted automatically.
Limits: 50 MB per file · 128 MB total per batch.
Add your Plain text file. MimiFile checks the format, converts it to EPUB, and provides a temporary download when the result is ready.
TXT does not contain ebook semantics such as chapters, a table of contents or styled headings. EPUB provides a reading container, but meaningful book structure may still need editorial work after conversion.
Current source limit : 50 MB per file. Up to 10 files can be submitted in a batch, subject to the global batch ceiling.
Plain text is accepted here as text/plain. The current source-file limit is 50 MB.
The result is produced as EPUB (application/epub+zip). Features unsupported by the destination format cannot be preserved.
Use this when a service, device or workflow accepts EPUB but your source file is Plain text.
Plain text and EPUB can represent document structure differently. MimiFile imports the Plain text source through its isolated office-processing pipeline and writes a new EPUB result rather than merely renaming the extension.
Plain text is primarily text-based. It carries much less page-layout information than a word-processing format, so a richer output cannot reconstruct formatting that was never present.
EPUB is suited to reflowable reading on e-readers and reading apps. Fixed page geometry is not its purpose.
The result is reflowable, so fixed page breaks, headers/footers, floating objects and print-oriented layout can be rearranged for reading screens. The conversion is performed with an isolated headless LibreOffice profile. Features that have no equivalent in the destination format can be changed, flattened or omitted.
Check character encoding, line breaks, special characters and whether text markup or whitespace was interpreted as intended. For EPUB, test the result in a real e-reader or reading app because reflow can differ by viewport and font settings.
The downloaded file uses EPUB. Check the result if the source contains transparency, animation, embedded fonts, metadata or other format-specific features.
