Edit PDF text online — in the same font

Click any line of text in your PDF and retype it. DukPdf keeps the original font wherever the font allows, and picks the closest match when it doesn’t — lines you don’t touch are left byte-for-byte identical. You can also add new text, shapes, images, highlights, and your signature. Everything runs in your browser: the file never leaves your device, there’s no watermark, and no account. To black out content permanently, use Redact PDF. To fill out a form, use Fill PDF Form. For a step-by-step guide, see our edit PDF guide.

When you edit a line, DukPdf re-encodes it through the font embedded in your PDF, so the new text renders in the exact same face as the rest of the page. If the embedded font doesn’t contain a character you typed, only the words that need it switch to the closest matching font — weight and style included. Everything you don’t touch is preserved byte-for-byte, so the rest of the document’s layout, spacing, and formatting cannot drift.

You don’t need Acrobat Pro to change text in a PDF. Open the file here, click the text, retype it, and download — free, in your browser, on any operating system. Acrobat puts text editing behind a subscription; DukPdf doesn’t.
