How to Sign a PDF in Google Drive (Free, No Add-On)

To sign a PDF that lives in Google Drive, download it, sign it in a browser-based signer such as Docsigns, and upload the signed copy back to the same Drive folder. It takes about two minutes, works on a laptop or phone, and needs no add-on or paid plan. Some Google Workspace business plans also include Google's own eSignature feature, which you can use if your account has it.

Google Drive is a place to store files, not to sign them. On most personal accounts, opening a PDF in Drive gives you a viewer with comments, not a signature tool. So the job splits into three parts: get the file out, sign it, put it back. Below is each step for desktop and phone, plus the details that trip people up, like ending up with two copies of the same file.

The quick version

1. In Google Drive, right-click the PDF and choose Download.
2. Open docsigns.online and upload the downloaded PDF.
3. Draw, type or upload your signature, drag it into place, and add a date if the form asks for one.
4. Download the signed PDF.
5. Back in Drive, upload the signed file, ideally as a new version of the original.

Your options for signing a Drive PDF

Method	What you need	Good for	Trade-offs
Download, sign in a browser signer, re-upload	Any Google account, any browser	Signing a document yourself, quickly	A couple of extra clicks to move the file
Google Workspace eSignature	An eligible paid Workspace plan	Sending a document to others to sign, inside Google	Not available on every account
Third-party Drive add-on	Installing an app from the Workspace Marketplace and granting it Drive access	Teams already using that service	The add-on gets access to your Drive; many have paid tiers
Print, sign, scan	A printer and scanner	Forms that insist on ink	Slow, and the scan is often harder to read

If you only need to put your own signature on a PDF and send it on, the first route is usually simplest, and it does not require giving a third-party app permission to read your Drive.

On a computer, step by step

1. Download the PDF from Drive

Find the file, right-click it and choose Download. If the PDF is open in Drive's preview, use the download arrow at the top of the screen. If you do not see a download option, the owner may have turned off downloading for viewers. In that case, ask them to share it with download access, or to send the file directly.

2. Sign it

Open the signer and upload the file. You can create a signature three ways: draw it with a mouse or trackpad, type your name and pick one of six cursive styles, or upload a photo of your handwritten signature. Choose a pen colour; some forms specifically ask for blue. Then drag the signature onto the signature line, resize it to fit, and add a date in the format the form uses. If the document has more than one place to sign, add a signature on each page that needs one. The how it works page shows the three steps with screenshots.

3. Download the signed copy

The result downloads as a PDF with no watermark. Open it once to check the signature sits where you expect and is not covering any printed text.

4. Put it back in Drive without making a mess

If you simply drag the signed file into Drive, you end up with two near-identical PDFs, and sooner or later someone opens the unsigned one. Two cleaner choices:

• Replace the original: right-click the original file, open File information or Manage versions (the exact label depends on your Drive version) and upload the signed PDF as a new version. The link and sharing settings stay the same, so anyone who had the old link now sees the signed copy.
• Keep both, clearly named: upload the signed copy with "signed" and the date in the file name, for example lease-2026-signed.pdf. Useful when you want to keep the unsigned original for reference.

On a phone

The same flow works from the Google Drive app on Android or iPhone.

1. In the Drive app, tap the three dots next to the PDF. On Android choose Download; on iPhone choose Open in or Send a copy and save it to Files.
2. Open docsigns.online in your phone's browser and upload the PDF from your downloads or the Files app.
3. Draw your signature with a finger, or type it, place it, and download the signed PDF.
4. In the Drive app, tap the + button, choose Upload, and pick the signed file.

Drawing with a finger is easier if you turn the phone sideways to get a wider canvas, and pinch to zoom in so you can place the signature precisely on a small line.

What about Word files stored in Drive?

If the document is a .docx in Drive, download it as is and upload it to the signer; DOC and DOCX are supported. One difference worth knowing: a PDF is signed in your browser and is not uploaded, but a Word file is first converted to PDF on a server before you sign it. The signed result is a PDF either way. If the file is a Google Doc rather than a Word file, use File > Download > PDF Document inside Google Docs first, then sign the PDF.

If someone shared the PDF so you could sign and return it

Check what the sender expects back. Often a signed copy by email is fine. If they want it in a shared folder, upload it there and check that they can see it, since uploading into a folder you do not own may require editor access. If they asked you to sign through Google's own eSignature request, you will get an email with a link that opens a signing view; follow that link instead, because it is how their copy gets completed and tracked.

Is a PDF signed this way valid?

An electronic signature like this is accepted for most everyday agreements: leases, offer letters, consent forms, invoices, NDAs, under laws such as ESIGN and UETA in the US and eIDAS in the EU. It is an electronic signature, not a certificate-based qualified digital signature, and a few kinds of document (wills, some property and court filings) need more than that. If you are unsure whether a particular document needs a specific signing method, ask the person who sent it. This is general information, not legal advice.

Common problems

• No download button: the owner disabled downloads for viewers. Ask for access or a direct copy.
• Two copies in Drive: use Manage versions next time, and delete or rename the unsigned one now.
• Signature looks huge or tiny: resize it on the page before downloading; it should fit the line like a pen signature would.
• The sender cannot open the file: check the sharing settings on the uploaded copy, which may not inherit the original's permissions if it is a new file.
