WordをPDFに変換

このツールでできること

This reads a .docx directly: the file is unzipped, its XML is parsed, and the document's structure is laid out afresh by our own typesetter. Headings, paragraphs, lists, tables, images and hyperlinks all come across. What does not come across is Word's own pagination - the text is re-flowed, so page breaks will not always fall where Word put them. For a CV, a letter, a report or a contract that difference is invisible; for a document whose layout is load-bearing, Word's own Save as PDF is the honest answer.

Use it when you need a PDF and Word is not to hand: a CV that an application form insists on receiving as a PDF, a contract you want to send in a format nobody edits by accident, or a document sitting on a phone where installing an office suite is not a realistic step.

仕組み

1. Drop your .docx files onto this page. Up to 20 at a time, each up to 100 MB.
2. Choose the paper size, orientation and margins. Normal margins are 56 points on every side, which sits close to Word's own default.
3. Leave keep hyperlinks on so web addresses become real, clickable annotations rather than blue text that does nothing.
4. Leave bookmarks from headings on and the PDF outline builds itself from your heading styles.
5. Under advanced options, switch on combine into one PDF if several documents should arrive as a single file.
6. Press Convert. Each document downloads as its own PDF unless you asked for them merged.

The conversion is a re-layout, not a re-render. Word's pagination is the product of Word's line-breaking, hyphenation and widow rules, and reproducing it exactly means reproducing all three. Instead the document's structure is measured against the paper you chose and flowed onto pages here, with the same widow and orphan control every conversion on this site uses. A heading is never left stranded alone at the foot of a page, and a single line is never left behind by itself.

Headers, footers and page-margin content are not carried across. The document model behind every conversion here describes flowing content - paragraphs, lists, tables, images - and it has no slot for a running header or a footer that repeats. If your document depends on a letterhead in the header, convert it first and then apply the letterhead with Stamp PDFs, which puts it on every page more reliably than a header ever did.

Fonts are the other honest limit. A Unicode font is embedded by default, about 2 MB of Noto Sans and Noto Sans Mono served from this site's own origin, so curly quotes, accents and Vietnamese diacritics survive. That set does not cover Chinese, Japanese, Korean, Arabic or Indic scripts, because the faces that would are tens of megabytes each. Characters it cannot draw are reported to you rather than quietly swapped for boxes.

Bookmarks build themselves from the heading styles. Heading 1 through Heading 6 become outline entries at the matching depth, so a long report arrives with a working navigation pane that nobody had to add by hand. It is also what makes a batch conversion usable: combine twenty documents into one PDF and each file's headings sit under its own branch of the outline rather than in a flat list.

A legacy .doc is a different format entirely and is not supported. The drop zone accepts one anyway, so it can tell you what to do about it instead of refusing the file with no explanation. Open it in Word, LibreOffice or Google Docs, save it as .docx, and come back.
