How it works
Add your Plain text file. MimiFile checks the format, converts it to Rich Text Format, and provides a temporary download when the result is ready.
Convert TXT to RTF when you need plain text inside a broadly supported rich-text document container for Word-compatible or legacy software.
TXT → RTF
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.

TXT has no rich formatting to preserve. RTF can store styling, but the conversion cannot know which lines should become headings, lists or other formatted structures unless the source already encodes them as text.
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 Rich Text Format (application/rtf). Features unsupported by the destination format cannot be preserved.
Use this when a service, device or workflow accepts Rich Text Format but your source file is Plain text.
Plain text and Rich Text Format can represent document structure differently. MimiFile imports the Plain text source through its isolated office-processing pipeline and writes a new Rich Text Format 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.
Rich Text Format is intended for editable word-processing content. It can preserve rich structure, but application-specific fields, styles, tracked changes, fonts or embedded objects may map differently.
Different document formats have different feature models. Keep the original when exact editability, typography, formulas, media or application-specific behavior matters. 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.
The downloaded file uses Rich Text Format. Check the result if the source contains transparency, animation, embedded fonts, metadata or other format-specific features.
