Free online RTF merger

Merge RTF files into one PDF

Drop several .rtf documents and get back a single PDF instead of a folder of them. Combine mode is already switched on below — every file is appended in the order you add it, each one starting on a fresh page, with bold, italics, colours, tables and pictures intact. Up to 20 files, nothing uploaded, no signup.

  • Combine mode preset
  • One page per document start
  • No upload
  • 100% free
  • Up to 20 files
Options — page size, combine into one PDF

Want a separate PDF for each file instead? Untick the combine option, or use the standard RTF to PDF converter.

How to merge RTF files into a single PDF

Three steps, all of them local. The documents never leave your browser tab.

  1. Add your RTF files in the order you want them

    Drag the .rtf files onto the drop zone, or click to pick them. They are merged in the order they appear in the list, so drop them one at a time — or in a single selection — in reading order. Up to 20 files, 25 MB each.

  2. Leave 'Combine every file into one PDF' ticked

    This page opens with combine mode already on, which is the only difference from the main converter. Each document starts on a fresh page, so chapters and letters never run into each other. Untick it and you get one separate PDF per file instead.

  3. Download the merged PDF

    Conversion starts the moment the files land — there is no upload step, because the merging happens in your browser. When the list turns green, press 'Download combined PDF' to save the single document.

Getting the order right

Merging is really two decisions: which files, and in what sequence. The converter appends documents in the order they sit in the list, and the list is built in the order you add them — so the sequence is entirely under your control, as long as you know that is what is happening.

The catch is multi-select. When you shift-click twenty files in Explorer or Finder, the browser receives them in whatever order the operating system chose, which is usually alphabetical and occasionally not. If the sequence carries meaning — chapters, dated correspondence, numbered exhibits — either drop the files one at a time in the order you want, or rename them with a numeric prefix (01-intro.rtf, 02-body.rtf) so alphabetical is the right order. Got it wrong? Press Start over and rebuild the list; nothing was uploaded, so there is nothing to undo anywhere else.

Why merge rather than convert one by one

A batch of RTF files almost never arrives as a batch by choice. Legacy systems export one file per record, mail-merge templates emit one per recipient, and case-management software produces one per document in a bundle. What you actually need to send is one file.

  • Upload forms take one attachment. Court e-filing portals, grant submissions and job applications typically want a single PDF, not a zip of twenty.
  • A merged PDF is smaller. Fonts and shared resources are embedded once for the whole document instead of once per file, so the combined PDF beats the sum of the individual ones.
  • It reads as one document. Page numbering, search and scrolling all work across the whole bundle rather than stopping at each file boundary.
  • It is one thing to keep track of. Archives, email threads and shared drives are far kinder to a single artefact than to a folder of near-identical names.

If you only have one file, or you want the outputs kept separate, the main converter does exactly that — and it will still hand you all the PDFs in one zip. New to the format? What is an RTF file explains what you are actually holding.

Merging RTF files — frequently asked questions

How do I merge several RTF files into one PDF?

Drop all the .rtf files onto the converter above. Combine mode is already switched on for you, so instead of one PDF per file you get a single merged document. It is free, there is no signup and no watermark, and you can merge up to 20 files in one go.

What order do the files end up in?

The order they appear in the list, which is the order you added them. A multi-file selection is handed over by your operating system in its own order — usually alphabetical — so if the sequence matters, drop the files one at a time, or name them 01-, 02-, 03- before you start. Use 'Start over' to clear the list and redo it.

Does each document start on a new page?

Yes. Every RTF begins on a fresh page in the merged PDF rather than continuing mid-page from the file before it, so a batch of letters, chapters or exhibits stays visually separated without you inserting anything.

What if the files have different page sizes?

With the default 'Keep the RTF's own size', each document keeps the page dimensions recorded inside it — so an A4 file and a US Letter file will produce a PDF with two different page sizes in it. That is sometimes what you want and sometimes not. To force one consistent size across the whole merged document, pick Letter or A4 from the Page size dropdown.

Are my files uploaded to merge them?

No. Parsing, typesetting and merging all happen in JavaScript inside this browser tab — there is no server endpoint for the documents to reach. This matters more for merging than for a single file, since a batch of documents is usually a whole case file, contract set or manuscript rather than one stray letter.

How many files can I merge, and how big can they be?

Up to 20 files per merge, each up to 25 MB. The merged PDF has no page limit of its own — the cap is your device's memory, and a few hundred pages is unremarkable.

Is the merged PDF bigger than the separate ones?

It is smaller than the sum of them. Fonts and repeated resources are embedded once for the whole merged document rather than once per file, so combining twenty short letters produces a PDF noticeably smaller than twenty individual PDFs zipped together.

Can I merge RTF files with PDFs I already have?

Not here — this tool takes .rtf files as its input. It merges RTF documents into one PDF; it is not a general-purpose PDF merger, so an existing PDF cannot be added to the batch.

Do I need Word, Acrobat or any install?

No. Merging documents is normally the part that pushes people toward paid software: Word can combine files but fights you about it, and Acrobat's merge is behind a subscription. This runs in any modern browser, including on a locked-down work machine or a Chromebook, with nothing installed.
