How to use find and replace
Upload a PDF and open the Search tool from the right sidebar.
Type the text you want to find.
Review all occurrences grouped by page.
Click a result to scroll to it in the document.
Replace a single match or replace all matches at once.
Current limitations
Search works on detected text items — not raw PDF binary content.
Phrases split across multiple PDF text fragments may not match perfectly.
Replace all is simple and may be slower on very large documents.
Private by design
All search and replace operations run locally in your browser. Nothing is sent to a server. After the site has loaded, you can turn off Wi-Fi and continue working.
