Is this tool really free?

Yes, all our PDF tools are completely free to use with no hidden costs, subscriptions, or per-file charges. We support the service through non-intrusive advertising, not by charging for basic document operations. You can use any tool as many times as you like, with no daily limits, file size restrictions, or account requirements whatsoever.

Absolutely. All PDF processing happens directly in your browser using local JavaScript and WebAssembly libraries. Your files are never uploaded to any server, never stored in the cloud, and never transmitted over the internet. The files remain entirely on your device from start to finish, giving you complete control over your sensitive and confidential documents.

What types of links can I add?

You can add clickable hyperlinks that open external URLs in the user's default web browser when clicked. The link appears as an invisible clickable region over the area you draw, activating when the user clicks on that region in a PDF reader. This is useful for adding clickable references, website URLs, product links, or any external resource that complements the document content.

Can I add links to specific pages?

Currently you can add links that navigate to external URLs. Internal page links that jump to another location within the same PDF (called internal hyperlinks or cross-references) work differently and can be created using the Add Bookmarks tool for chapter-level navigation. Both types of navigation are part of the PDF specification and are supported by all standard PDF readers.

Will the links be visible or invisible in the PDF?

Links are added as clickable areas without any visible indicator by default — the existing text or image in the area remains unchanged in appearance. In some PDF readers, hovering the mouse over a link area shows a cursor change or a URL tooltip, but there is no visible box or underline added to the document unless you specifically design the source text to look like a hyperlink.

Can I add links to existing text?

Yes, simply draw the link area over the text you want to make clickable. The text itself is not modified — the link is a separate interactive layer placed over the text region. This is the standard way to create clickable links in PDF documents without altering the visual appearance of the underlying text.

Do links work across all PDF readers?

Yes, external URL links are a standard feature of the PDF specification supported by all compliant PDF readers including Adobe Acrobat Reader, Chrome's built-in viewer, Safari, Firefox, Foxit Reader, and Preview on macOS. When a user clicks the link area, the PDF reader passes the URL to the operating system, which opens it in the default web browser.
