How to sign a PDF in Chrome

Checked 20 September 2026

Google says the Chrome PDF viewer lets you "highlight, annotate or draw on a document" and "fill in and sign paperwork". That is true — with one catch that trips people up constantly.

The text tool is a ChromeOS feature. Google's own help pages state: "You can't add text annotations to your PDFs in the Chrome Browser." On Windows and macOS you can draw, but you cannot type onto a form that has no fields.

Step by step

  1. 1Open the PDF in ChromeDrag the file onto a Chrome window, or right-click it and choose Open with → Google Chrome.
  2. 2Type into any real form fieldsIf the document has form fields, click into them and type. This works everywhere, including on Windows and macOS.
  3. 3Open the annotation toolsSelect Annotate in the viewer toolbar to reveal the pen, highlighter and eraser.
  4. 4Sign with the penChoose the pen, pick a colour and draw your signature. Google notes this feature "is for convenience and doesn't provide signature verification or security".
  5. 5Save your copyDownload the annotated file from the viewer. On a Chromebook, choose Save; elsewhere use the download button.

What Chrome can't do

  • No typing onto flat forms in the Chrome browser — the text tool exists on ChromeOS only.
  • No saved signature: you redraw it each time.
  • No tick or date fields, no flattening, no Word export.
  • Drawing with a mouse produces a signature that looks drawn with a mouse.

Finish it here instead

Type onto the page, tick the boxes, add the date and a signature you can reuse, then save a flattened PDF. It runs in this browser — your file is not uploaded.

Questions

Why is the text tool missing in Chrome?
Because it belongs to ChromeOS rather than the browser. Google states directly that you cannot add text annotations to PDFs in the Chrome browser.
How do I type on a PDF in Chrome on Windows?
You cannot with the built-in viewer unless the PDF has form fields. Use a browser tool that draws text onto the page — PDFpad does this without uploading the file.
