Edit PDF — frequently asked questions

Can I edit the existing text in a PDF?+

Yes — the Edit Text tool lets you change words already in the document, within the limits of the original fonts. To lay new text on top, use Add Text.

Is there one tool that does everything?+

PDF editing is split into focused tools so each one stays simple. This page points you to the right one for the change you need.

Do I need an account to edit a PDF?+

No. Every editing tool works immediately in your browser, with no sign-up and nothing uploaded.

ファイルはサーバーにアップロードされますか？+

いいえ。ここにあるすべてのツールはファイルを完全にお使いの端末内で処理し、サーバーには何もアップロードされません。唯一の例外はAIツールで、作業のために抽出したテキスト（ファイルそのものではありません）をClaudeに送信します。

ファイルサイズの制限はありますか？+

当サイトが設ける人為的な制限はありませんが、処理はブラウザ内で行われるため、非常に大きなファイル（500MB以上、1,000ページ以上など）はお使いの端末のメモリによって制限されます。
