Find and Replace Text in PDF Documents

The AfroTools PDF Find & Replace tool lets you search for text within any PDF document and visually replace it with new text. The tool renders your PDF in the browser, highlights all matching text occurrences, and lets you navigate through matches by page. When you apply replacements, white rectangles cover the original text and your replacement text is drawn over it in Helvetica font.

All processing is client-side. Your PDF never leaves your browser, making this tool suitable for documents that contain private or sensitive information. The tool uses pdf.js for text extraction and rendering, and pdf-lib for applying the visual overlay modifications.

Frequently Asked Questions

Is my PDF uploaded to a server?
No. All processing happens entirely in your browser. Your PDF file never leaves your device. The tool uses pdf.js for rendering and pdf-lib for modifications, both running client-side.
How does the visual replacement work?
The tool draws a white rectangle over the original text and then draws the replacement text on top. This is a visual overlay, not a true text edit. The original text may still be extractable from the PDF data layer.
Can I use this for redacting sensitive information?
This tool performs visual replacement only. The original text may still be present in the PDF data layer. For true redaction where the original text is permanently removed, use a dedicated PDF redaction tool instead.
Does find and replace support case-insensitive matching?
Yes. By default the search is case-insensitive. You can enable the Case Sensitive toggle to match exact letter casing. You can also enable Whole Word matching to avoid partial matches within longer words.
What font is used for the replacement text?
Replacement text is rendered in Helvetica, a standard PDF font. The font size is automatically calculated to approximate the size of the original text being replaced.
