PDF Sign/Date/Fill

About this tool

PDF Sign/Date/Fill adds a drawn, typed, or uploaded signature, stamps a date, places text, and fills AcroForm fields in the browser. Download writes the values and flattens them. The file stays on the device.

Add drawn, typed, or uploaded signatures, stamp dates, place text, and fill AcroForm fields. The file stays in memory on your device; download writes and flattens values for most viewers.

How to use it

1. Open the PDF. The document is loaded in memory in the tab. It is not posted to a server.
2. Add marks or fill fields. Place a drawn, typed, or image signature, a date stamp, or freeform text. Existing AcroForm fields can be filled. The original body text of the PDF is not edited.
3. Download. Filled values are written into the PDF and flattened so most viewers show them as static content.

What download changes

If you fill an AcroForm name field and download, the file contains that value flattened into the page. Reopening it in a typical viewer shows the text without an editable field.

Sources

• In-browser PDF library — Signing and form fill use the same local PDF stack as the rest of the site. Bytes are not stored in a database.

Limits

• This does not merge, split, or raster-compress. Those operations are on the PDF toolkit page.
• Flattening makes the answers visible and no longer live form fields in most viewers.
• A signature image here is a visual stamp. It is not a cryptographic certificate signature.
