How to add a clickable link to a PDF

To add hyperlink to PDF pages, you draw a clickable area over the text or picture and give it a web address. In our free PDF Studio, switch to Advanced, choose Link on the Edit tab, drag a box over your website, email or logo, type the address (starting with https:// or mailto:) in the Settings panel and press Save PDF. Anyone who opens the new file can click or tap that area to visit the page. It all happens in your browser, so the file is not uploaded.

Below are the exact steps, how to make the link visible, ready-made address formats for email and WhatsApp, and fixes for links that don't work.

Why add links to a PDF

A PDF often travels further than a web page. A CV sent to an employer, a restaurant menu shared on Facebook, a price list on WhatsApp or a brochure for a training centre all get opened on phones. If your website, portfolio or contact number in that PDF is clickable, the reader is one tap away instead of having to copy and type it.

Good candidates for links:

• Your portfolio, LinkedIn profile or GitHub on a CV
• An order or booking page on a menu or price list
• An email address that opens a new message
• A WhatsApp chat with your business number
• A logo that opens your website

How to add hyperlink to PDF text, step by step

1. Open the PDF. Go to PDF Studio and click Open PDF files, or drop the file onto the page.
2. Switch to Advanced. PDF Studio starts in Simple mode. Tap More tools, or choose Advanced at the top of the Settings panel on the right.
3. Choose Link. On the Edit tab, click Link. The hint reads "Drag a box over the text or picture that should open a web page."
4. Drag a box. Draw a box that covers the words or the logo. Make it a little larger than the text, so it is easy to hit with a finger.
5. Type the address. In the Web address field on the right, replace https:// with the full address, for example https://example.com/menu. The box on the page shows the address, so you can see which link is which.
6. Add more links. Choose Link again for each one. You can put links on any page.
7. Save. Press Save PDF (or Ctrl+S). The new file, named with -edited at the end, goes to your downloads; your original stays as it was.

To change a link later in the same session, choose Select, click the box and edit the address on the right. Delete removes it.

Address formats that work

Link to	Type this	Example
A website	https:// and the address	https://example.com
An email	mailto: and the address	mailto:[email protected]
A WhatsApp chat	https://wa.me/ and the full number with country code, no +, spaces or leading 0	https://wa.me/8801XXXXXXXXX

For a Bangladeshi mobile number such as 017XXXXXXXX, drop the first 0 and put 880 in front, so the WhatsApp link ends in 88017XXXXXXXX.

PDF Studio only saves links whose address starts with https://, http:// or mailto:. While an address looks incomplete, the panel warns "Enter a full address: the link is left out until it's valid". Don't save until that warning is gone.

Make the link visible

The clickable box has no border in the saved PDF. That keeps your design clean, but it also means nobody knows the text is a link unless it looks like one. Two easy ways to fix that, both in PDF Studio:

• Underline it. On the Comment tab, choose Underline and drag along the text. It draws a thin blue line, the classic link look.
• Write link text yourself. On the Edit tab, choose Add text, pick the blue colour on the right and type something like "Order online" or "View my portfolio". Then draw the Link box over it.

Words such as "Visit our website" or "Chat on WhatsApp" work better than a bare address, especially on a small screen.

Test before you send

Open the saved file and click every link. Try it in the PDF reader your readers will most likely use: the PDF viewer built into Chrome or Edge on a computer, and the default viewer on an Android phone or the Files app on an iPhone. Some readers ask you to confirm before they open a website; that is normal and the reader's own safety setting.

Common problems and how to fix them

The link doesn't open at all

Check the address on the right for a typo or a missing https://. A box whose address doesn't start with https://, http:// or mailto: is left out of the saved file, and one that still reads just https:// goes nowhere.

The link opens the wrong page

Copy the address from your browser's address bar instead of typing it. Long addresses are easy to get wrong by hand.

The link stopped working after I sent it

Some apps turn a PDF into images for a preview, and a picture can't hold links. Ask the reader to open the file itself in a PDF reader. The same applies if you convert the PDF to JPG or PNG, or print it and scan it again.

The PDF is too big to share

Turn on compression before saving (the Save tab in Simple mode, or Compress on save in Advanced), or use Compress PDF. See how to compress a PDF to under 1 MB for the details.

Other things you can add while the file is open

PDF Studio can do the rest of the finishing in the same session: a photo or logo (see how to add a photo or logo to an existing PDF), page numbers, a password or a watermark. For a watermark on every page with more layout options, there is also Add Watermark to PDF.

Quick checklist

• Advanced mode on, Edit tab, Link
• Box drawn a little larger than the text or logo
• Full address typed: https://, mailto: or https://wa.me/ with the country code
• Link made visible with blue text or an underline
• Saved PDF opened and every link tested on a phone and a computer
• The PDF itself sent, not a picture of it
