Merge documents and images into DOCX or PDF online for free

Yes. You can mix different formats — DOCX, DOC, PDF, RTF, ODT, TXT, MARKDOWN, HTML and JPG or PNG images — in a single merge operation. All files are combined in the order you arrange them, and the result is saved as one DOCX or PDF file.

Choose DOCX if you need to edit the merged document in Microsoft Word or Google Docs afterwards. Choose PDF if you want a read-only file that looks the same on every device and is easy to share or print.

Free users can merge up to 5 documents per operation with a 1 MB file size limit per document. PRO users can merge up to 50 documents at once, without file size limit. But if you're merging really big documents, you might run into server timeouts. If that's the case, we suggest using our Doc Converter Pro Windows Desktop App.

Your files are transferred over an encrypted HTTPS connection, processed on the server, and then automatically deleted. We do not store, read, or share the contents of your documents.

No installation is required. The merge tool runs entirely in your browser. It works on Windows, Mac, Linux, and mobile devices — no plugins or extensions needed.

The merger preserves the formatting of each source document as closely as possible. Complex layouts, images, tables, and styles are retained. Merging to DOCX gives the best fidelity for editable content, while merging to PDF locks in the visual appearance.
