Frequently Asked Questions
Yes, completely free. No signup required, no watermarks, and no usage limits for RTF files up to 50 MB.
RTF (Rich Text Format) is a document format developed by Microsoft in 1987. It encodes text and formatting using plain-text control codes, making it readable by virtually every word processor including Word, LibreOffice, Apple Pages, and TextEdit.
Yes. Files are transferred over encrypted HTTPS and automatically deleted from our servers immediately after conversion. Nothing is stored.
Core formatting including paragraphs, headings, bold, italic, and lists is preserved. Fixed layout elements like print margins, headers, and footers may not translate to EPUB's reflowable design.
Newer Kindle devices (2022 and later) support EPUB natively. For older models, use the EPUB to MOBI converter on ChangeThisFile to create a Kindle-compatible file.
Yes. Heading styles in the RTF file are mapped to EPUB heading structure, creating navigable chapters in the output EPUB file.
Embedded images in the RTF file are generally preserved and included in the EPUB output. Complex embedded objects like embedded OLE objects may not convert cleanly.
Most RTF files convert to EPUB in under ten seconds. Larger documents with many embedded images may take slightly longer.
RTF files up to 50 MB are supported for free conversion. Image-heavy RTF files may be larger — ensure your file is under 50 MB.
Conversion is performed by LibreOffice running on our secure server. LibreOffice loads the RTF document and exports it to EPUB 3 format.
EPUB is a reflowable format — text reflows to fit the screen and can be resized. PDF is fixed-layout. For reading long-form content on a phone or e-reader, EPUB provides a much better reading experience than PDF.
Yes. Use Calibre (free desktop app) to edit the EPUB's metadata, add a cover image, set the author name, ISBN, and other fields after the initial conversion.
