How adding links works
A hyperlink inside a PDF is technically a link annotation: a rectangle placed over part of the page, paired with an action such as "open this URL." It has nothing to do with how the underlying text looks — you're not turning text blue or underlining it, you're attaching a clickable zone on top of the page that any standard PDF viewer recognizes and can act on. Most tools leave that rectangle completely invisible; this one gives it a thin, deliberate outline so you and your readers can actually see where every link is.
This tool lets you draw that rectangle directly on a live preview of your PDF. Drag to sketch a custom-sized box, or tap once to drop a sensible default size, then drag its middle to reposition it or a corner handle to resize it before you're happy with the placement. Type or paste the destination URL — or a mailto: address for a one-tap email link — and it's ready.
Everything runs on your own device using your browser's PDF-rendering and PDF-writing libraries. The page you see is rendered locally, the rectangle-and-URL data you create never leaves your machine, and the final file is assembled and handed back to you the same way — no upload step, no account, and no server ever sees the document.
Common use cases
- Turning a resume or portfolio PDF's contact line into a working mailto: link
- Adding "visit our website" or social links under a logo in a PDF brochure or one-pager
- Linking a citation or footnote number to the source it references
- Making a scanned or flattened form's printed URL actually clickable again
- Pointing readers of a report or proposal to a booking page, survey, or payment link

Add Links to PDF — frequently asked questions
No — leave it off and https:// is added automatically when you export. Addresses starting with mailto: (for a one-click email link) also work as-is.
Yes. Drag the middle of a placed link to move it, or drag one of its four corner handles to resize it — nothing is locked in until you export, so you can fine-tune every box's position and size first.
Yes — place as many as you need, across any page, before exporting. Each one is listed in the sidebar with the page it's on.
Yes — every link gets a thin colored outline in the exported PDF, both while you're placing it and after the file is saved and reopened, so you and your readers can actually see where it is instead of discovering it only by hovering. It's an outline only, not a filled box, so it won't cover the text or image underneath it.
Not yet — this tool currently creates external URL and mailto: links only. Linking to another page in the same document is a common request and something we're considering for a future update.
A link is skipped if its URL field is empty, or if it uses a scheme this tool blocks for safety (like javascript: or data:) rather than a real web address or email. The sidebar flags any link with an unsafe or empty address before you export, so you can fix or remove it first.
It depends on the PDF/A level. Most PDF/A-2 and PDF/A-3 conversions keep link annotations intact, while the older PDF/A-1a profile strips interactive annotations, including hyperlinks. Check your archiving tool's settings if link preservation matters.
Yes — no sign-up, no daily limit, and the file never leaves your browser. Every link is added to the PDF using your device's own processing, so nothing is uploaded to a server at any point.
