A Word file opens differently on every machine — fonts substitute, page breaks drift, and your carefully placed content reflows. A PDF opens identically everywhere. That is the entire reason the format exists, and why final documents should travel as PDF.
Converting locally
The Word to PDF tool converts .docx files in your browser — the document never uploads, which matters when it is a contract or an offer letter. A preview shows the result before download.
Pre-flight checks that prevent surprises
Uncommon fonts: exotic fonts may be substituted; standard families (Calibri, Arial, Times, Georgia) convert most faithfully. Track changes: accept or reject all revisions first, or reviewer comments ride along into the PDF. Headers and page numbers: verify they appear on the correct pages in the preview — or add numbering afterward with the page numbers tool.
After conversion
The PDF is your distribution copy; keep the .docx as the editable master. Need a signature on it? The signing guide takes over from here. Sending several documents together? Merge them into one packet. And if you ever lose the master and only have the PDF, the reverse conversion recovers an editable version.
