PDF Viewer

Last updated: 2026-03-23

The PDF viewer renders your documents directly in the browser. The toolbar provides page navigation and zoom, plus a redaction mode with keyword search. Click any PDF in the document browser, or follow an AI agent citation, and the viewer opens to the relevant page.

PDF viewer toolbar controls

The PDF viewer toolbar sits at the top of the panel and provides quick access to page navigation and zoom controls. Here is what each group does.

Page navigation in the PDF viewer

On the left side of the toolbar, you see your current page number and the total page count. Use the arrow buttons to move forward or backward one page at a time, or jump straight to the first or last page. You can also type a page number into the input field to go there instantly.

For long documents, typing a page number is the fastest way to reach a specific spot. The page counter updates automatically as you scroll, so you always know where you are.

Zoom controls in the PDF viewer

The zoom buttons increase or decrease magnification. Click zoom-in to enlarge the page, or zoom-out to shrink it. The current percentage appears between the two buttons so you can check your magnification level at a glance.

Zooming is especially helpful for fine print, handwritten annotations, or detailed exhibits. The viewer keeps your scroll position when you change the zoom level, so you do not lose your place.

Keyword search in PDF viewer redaction mode

When redaction mode is active, a keyword search panel lets you find specific terms or phrases in the open PDF. Type your search term and the viewer highlights every matching occurrence. Use the navigation controls to step through each match.

This is especially useful when reviewing lengthy contracts, pleadings, or production documents. Locate every mention of a key term and apply redactions right there.

PDF viewer redaction mode

The PDF viewer includes a redaction mode you toggle from the toolbar. Once active, draw redaction boxes directly on the document by clicking and dragging over the content you want to redact. Each proposed redaction appears as a highlighted overlay on the page, letting you review your selections before applying them.

You can also use the AI agent to propose redactions across multiple documents. Manual redaction in the viewer works best for fine-tuning individual pages or handling passages that need careful attention. See AI agent capabilities for more on automated redaction workflows.

Opening PDFs in the document viewer

You can open a PDF two ways. First, click a PDF in the document browser panel on the left. It opens in the center viewer panel with the toolbar, page count, and controls ready to go.

Second, use AI agent citations. When the agent references a specific page or passage, it provides a clickable citation link. Click it, and the PDF viewer opens and scrolls to that location. This lets you verify the agent's findings without manually searching through the file.

Both methods give you the same toolbar controls. The viewer starts at a default zoom level each time you open a PDF.

Frequently asked questions

Can I select and copy text from a PDF in the PDF viewer?
Yes. With redaction mode off, click and drag to select text, then copy it to your clipboard. This works for PDFs with a selectable text layer. Scanned documents without OCR text may not support text selection.
How does the PDF viewer handle large documents?
The PDF viewer loads pages progressively as you scroll, so even documents with hundreds of pages open quickly. You can jump to any page using the page number input without waiting for the full document to load.
Can the PDF viewer display scanned documents?
Yes. Scanned PDFs display as page images in the viewer. During processing, Hintyr extracts text from scanned pages using optical character recognition (OCR). That extracted text then becomes available to the AI agent for search and analysis.
Can I print a PDF from the document viewer?
Download the PDF from the file actions menu in the document browser, then print it from your local application. If the document has been redacted or Bates-stamped, the download reflects those applied stamps.
