What to expect when converting PDF to DOCX

一般的なファイルサイズの変更
50–150% — varies widely by PDF complexity

A 2 MB text-heavy PDF typically becomes 1 – 4 MB as DOCX. Image-heavy PDFs may stay roughly the same size.

品質: Text and basic formatting transfer cleanly. Complex layouts, columns, and embedded fonts may shift. Scanned PDFs require OCR (use our Image to Text tool first).

以下に最適: editing PDF content in Word, extracting text for rewriting, repurposing documents.

次の場合は避けてください。 the PDF is a final-form contract or has carefully designed layout you want preserved.

ヒント: For scanned PDFs (PDFs that are really images of pages), conversion to DOCX produces an unedittable image inside Word. Run OCR first to get real text.

実際の使用例

PDF to DOCX — The most-searched document conversion — edit a "final" PDF

PDF → DOCX is the single most-searched document conversion. Use cases dominate: a contract or proposal you need to redline, a CV template downloaded as PDF, a lecture note or research paper you're annotating for a review. Modern conversion preserves paragraphs, tables, and inline formatting on text-based PDFs. Scanned PDFs (images inside) need OCR first — image-only PDFs convert to a DOCX with the image embedded rather than editable text.

出力形式について

DOCX が正しい出力の場合

DOCX は Microsoft Word の最新形式であり、編集可能で変更の追跡が容易で、企業ドキュメントのワークフローで主流です。受信者がコンテンツを編集する必要がある場合 (法的契約の朱書き、編集上の改訂、人事テンプレート) は DOCX に変換します。固定の最終成果物を意図したものは DOCX に変換しないでください。レイアウトは Word のバージョンやプラットフォームによって異なります。

Turn a PDF back into an editable DOCX

PDF のレイアウトがフリーズします。契約条項を編集したり、レポートを更新したり、他の人の文書のタイプミスを修正したりするなど、凍結を解除する必要がある場合があります。

  1. 1

    Upload the PDF

    The tool accepts PDFs up to 10 MB on the free plan, up to 1 GB on Pro. Text-based PDFs — the kind exported from Word, LaTeX, or a browser — convert cleanly. Scanned or image-only PDFs need OCR first; the tool detects this and runs the OCR pass automatically where it can.

  2. 2

    ツールに構造を推測させます

    PDF has no built-in concept of paragraphs, headings, or tables — the conversion reconstructs them by analysing the visual layout. A well-formatted source produces clean output; a source with unusual columns, sidebars, or footnotes may need light cleanup in Word afterwards.

  3. 3

    変換してダウンロード

    The output DOCX is ready in a few seconds. Open it in Word, Google Docs, or LibreOffice — everything you need to edit is there. Both the PDF you uploaded and the converted document are permanently deleted from our servers within 30 minutes.

What survives the trip back to DOCX

Text content, paragraph breaks, most heading styles, tables in most cases, inline images, hyperlinks, and basic formatting (bold, italic, underline) all come through. Multi-column layouts get re-flowed into single columns unless explicitly preserved. Custom fonts substitute to the closest common equivalent. Complex diagrams and vector artwork typically embed as images.

Things that trip people up

  • Scanned PDFs need OCR. If your source is a scan or a photograph of pages, the visible "text" is really image content. OCR turns that into real text — the tool runs it automatically, but quality depends on how clean the source scan is.
  • Round-trip loss is real. Converting PDF → Word → PDF loses subtle formatting on each pass. If you have the option, edit at the original source rather than round-tripping.
  • Tables aren't always tables. A PDF "table" might be a grid of text boxes without underlying structure. The conversion does its best, but stubborn cases sometimes come through as loose text — a quick manual cleanup fixes it.
  • パスワードで保護された PDF にはパスワードが必要です。 Adobe Reader でロックされた PDF は、同じパスワードを入力するまでツールにロックされたままになります。

When you actually need to edit a PDF

Six real reasons to unfreeze a PDF back into DOCX.

Editing a contract clause someone sent as PDF

You've received a PDF contract and need to negotiate a specific clause. Converting to DOCX gives you a proper editable document — make your changes, convert back to PDF, send it back. Cleaner than dedicated PDF editors for anything more than a single-word tweak.

Reusing content from an older report

The original DOCX source is long gone, but you still have the archived PDF. Converting recovers the underlying text so you can pull passages, tables, or references into a new document without retyping.

Pulling data from a PDF into a spreadsheet

Bank statements, invoices, and reports often arrive as PDFs full of tabular data you need to analyse. Converting to an editable format (Excel especially) lets you sort, filter, and pivot without manually re-entering rows.

Translating a document

Translation memory tools, DeepL, and Google Translate work far better with editable DOCX documents than with PDFs. Converting first lets the translation carry paragraph structure and inline formatting through cleanly, rather than emerging as a wall of text.

Making a PDF accessible

A scanned or image-only PDF is invisible to screen readers. Converting to DOCX — with OCR where needed — extracts the real text so assistive technology can read it aloud, and so search can find it later.

Splitting a long PDF into working pieces

A 200-page PDF is one big frozen block. Converting to DOCX lets you paste chunks into new documents, distribute sections to different owners, and generally work with the content instead of just reading it.

PDF形式について

PDF (Portable Document Format) was created by Adobe in 1993 and has since become an ISO standard (ISO 32000). It preserves the exact layout, fonts, images, and formatting of a document regardless of which device, operating system, or software is used to open it. PDF is the universal standard for sharing documents that must look the same everywhere, from legal contracts to academic papers.

Beyond simple document viewing, PDF supports interactive forms, digital signatures, AES-256 encryption, accessibility features, and embedded multimedia. The PDF/A variant is specifically designed for long-term archival of electronic documents. While PDFs are primarily view-only by default, they can be made editable with the right tools. PDF remains the go-to format for official documents, printable materials, and any content that requires consistent presentation across platforms.
