Add clickable links to a PDF

Make clickable areas easy to use

Draw the rectangle around the complete phrase or visual control, not only a few letters. Leave enough height for comfortable mouse and touch selection, but avoid covering nearby links. Invisible outlines usually look best when the underlying text already signals a destination. A visible outline can help when the linked region would otherwise be unclear.

Use meaningful link descriptions such as “Open the warranty registration page” or “Go to Appendix B.” Descriptions can help identify annotations in PDF software that exposes them, but adding a description alone does not turn an untagged PDF into a fully accessible document. Link purpose should still be clear from the visible page content.

For a new visible label, choose whether readers see the description, the website or page destination, or custom text. Adjust the text from 6 to 72 pt and choose a color. Blue is used by default because readers commonly recognize blue underlined text as a link. Preview the result and enlarge the clickable area if the chosen text size needs more room.

Insert an image with a link

A logo, button, product picture, QR companion graphic, or call-to-action image can be placed directly on a PDF page and given either a website destination or an internal page destination. The inserted picture becomes permanent page content, while a normal link annotation above it provides the click behavior. PNG, JPG, and WebP input are accepted and prepared locally for PDF compatibility.

Resize the image using its corner handles, then use Preview links to check the visible outline and destination. If the image itself clearly looks clickable, you can deliberately choose an invisible outline. Otherwise, keep the default blue outline so readers can recognize the interactive area.

Find web addresses without automatic changes

The Find web addresses command reads searchable text on the open page and looks for complete HTTP, HTTPS, or www addresses. It presents possible links in the settings panel so you can add or skip each one. This review step prevents ordinary text, dates, or punctuation from silently becoming an incorrect link.

Image-only scans do not contain searchable words. You can still draw links manually on them. If you want address suggestions from scanned text, first create a searchable copy with OCR PDF, then add and verify links on that copy.

Security and destination rules

LocalPDFLab creates only HTTP and HTTPS website actions and direct destinations to pages within the current PDF. It blocks script URLs, local file paths, application launches, form submission actions, and links to another PDF. Imported actions that do not meet the safe editable set are left unchanged and are not executed in the workspace.

Previewing a website link first displays the destination host and requires confirmation before opening a new tab. Even a legitimate link can lead to a site that later changes, so review the domain carefully and use HTTPS whenever it is available.

Check the finished PDF before sharing

• Open the downloaded copy in the PDF viewer your audience is likely to use.
• Test each website address and confirm the expected domain and page.
• Test internal links after the final page order has been set.
• Check that link rectangles do not overlap unrelated words or controls.
• Keep an unsigned original because saving changes invalidates existing digital signatures.
