About PDF Editor

The PDF Text Editor lets you change what's on a PDF page and download the result — all in your browser, with no upload. The most reliable way to "edit" text works on every PDF (even scanned ones): use White-out to cover the old text, then Add Text to type the replacement on top in any font, size, and colour. You can also add text, labels, and notes anywhere — ideal for filling non-interactive forms and completing documents. On text-based PDFs there's also a best-effort in-place edit (click a word to change it, with closest-font matching). Because everything runs locally, confidential contracts, payslips, and medical records never leave your device.

Why Use PDF Editor?

How It Works

The PDF is rendered to a canvas with pdf.js. "Add Text" places new text boxes at your chosen position; "White-out" draws white rectangles over existing content so you can cover and replace it; the optional in-place edit reads each text item's position and font via pdf.js and redraws your change at the same coordinates using the closest standard font (Helvetica, Times, or Courier). On save, pdf-lib applies the white-out rectangles, added text, and any in-place edits to the document and serialises it for download. True font-for-font editing of embedded fonts isn't possible in any browser tool, which is why white-out & replace is the dependable approach. No server is involved.

Frequently Asked Questions

How do I edit text in a PDF for free?

Open your PDF in the editor. The reliable way that works on any PDF: use White-out to drag a box over the old text, then switch to Add Text and type the replacement on top. On text-based PDFs you can also use Edit Text mode to click a word and change it directly. Download when done — no account needed.

Can I edit a scanned PDF?

Yes — for scanned PDFs (which are images with no real text), use White-out to cover the area and Add Text to write on top. True in-place text editing only works on PDFs that contain actual text, but white-out & add works on everything.

How do I add text or fill a form in a PDF?

Switch to Add Text, click "Place", then click anywhere on the page to drop a text box. Choose font, size, colour and bold, and drag it into position — ideal for non-interactive forms.

Is my PDF uploaded to a server?

No. All processing uses PDF.js and pdf-lib entirely in your browser. Your file is never sent anywhere — safe for contracts, payslips, and confidential documents.
