Where RTF files come from
RTF files are created by WordPad on Windows, TextEdit on Mac, older office suites, and many programs that export reports or letters. They open on most computers, but they look different depending on the program, and many portals require PDF.
What happens when you convert
The tool reads the text of the RTF file — including special and accented characters — and lays it out on A4 pages in a clean standard font, keeping your line breaks. Each page is saved into the PDF as a picture, so it looks the same almost everywhere but the text is not selectable.
What is not kept
RTF formatting such as fonts, bold and italic, colours, tables, headers and footers, and embedded pictures is not reproduced — the PDF contains the words in a plain, readable layout. For documents where formatting matters, open the RTF in Word, LibreOffice or WordPad and use their own PDF export or print-to-PDF.
Common problems and how to fix them
A table appears as loose text: tables are not rebuilt; use Word's own PDF export for tabular documents. Characters look wrong: the RTF used an unusual code page; open it in Word and save as .docx, then use Word to PDF. You need selectable text: run OCR PDF on the result.
Good habits
Use this tool for plain letters, notes and text exports, keep the RTF as the editable copy, and check the PDF for line breaks before sending.
