How we handle your data

RTF to PDF

Convert an RTF report exported by lab, logging or legacy software into a PDF record with its tables and headings kept in place. Your file stays in your browser.

Choose your document

Choose an RTF file and convert it to PDF. The first conversion prepares the local Office engine and may take a moment; the next file on this page is faster.

Local limit: 10 MiB per document

Choose a document, then convert it to PDF.

Processing happens on this device. Keep this tab open until your PDF is ready.

Try an example

Two PDF pages: an amount of 148.50, English and Russian text and a table on the first page.

Download sample RTF

Select the downloaded sample and convert it. Two PDF pages: an amount of 148.50, English and Russian text and a table on the first page.

What to expect

Text, images and page layout are converted together. Fonts and complex formatting may differ from your Office editor; check your PDF before sharing.

Large documents may exceed your device’s available memory. If conversion fails, try a smaller document or another device.

Help with conversion

The converter does not start

Check your connection while the converter prepares itself, then retry. This converter needs a modern browser and sufficient memory.

My document could not be converted

Open the document in your editor and save a new RTF copy. Password-protected, damaged or unsupported files may fail. The input limit is 10 MiB and the PDF output limit is 20 MiB.

Processing takes too long

Preparing the converter stops after two minutes; conversion stops after one minute. You can cancel during processing and restart with a smaller document.

A practical guide

Convert RTF software exports to PDF records

  1. Select the RTF report exported by the software.
  2. Convert it to a fixed PDF copy.
  3. Verify table rows, units and timestamps against the export.

Try this example

Convert an RTF instrument report with a 12-row results table; confirm all 12 rows and the timestamp header appear in the PDF.

Before you start: Simplified RTF from some software can drop table borders or images; compare values with the source before filing.
