How to Find and Replace Text in a PDF
July 6, 2026 · 4 min read
Discovering a client's name is misspelled throughout a 40-page contract, or that an old company name still appears in dozens of places across a long report, is frustrating. Manually finding and fixing each instance one at a time takes forever. With a built-in find and replace tool, you can locate every occurrence of a word or phrase in a PDF and swap them all in one click.
Why can't you just "edit" a PDF like a Word document?
Unlike a Word document, a PDF doesn't store text as reflowable paragraphs — it stores a sequence of precisely positioned drawing operations for each character. That means "find and replace" in a PDF first requires figuring out exactly where each character sits, then covering the old text accurately and placing the new text in the same spot with roughly the same font and size — all while keeping the rest of the page intact.
Step-by-step: find and replace text with techyworks
- Step 1 — Open your document: Go to techyworks.online and drop your PDF onto the editor.
- Step 2 — Open the search bar: Press Ctrl+F (or Cmd+F on Mac), or click the magnifier icon in the toolbar.
- Step 3 — Search: Type the word or phrase you're looking for. Every match in the document is highlighted instantly, with the current match shown in a different color. Use the arrows to step between results.
- Step 4 — Open the replace row: Expand the replace row and type the new text.
- Step 5 — Replace one or all: Replace just the current match, or click "Replace All" to change every occurrence in the entire document with a single click.
- Step 6 — Download: Once you're happy with the result, download the updated PDF. Everything was generated locally — your document was never uploaded.
Common use cases
- Fixing typos in bulk: If one misspelled word repeats through a long document, fix it everywhere in one click.
- Updating templates: Swap out a client name, date, or reference number in a contract template before reusing it.
- Rebranding: If an organization changed its name, update every reference throughout an old report or handbook.
- Redacting sensitive info: Replace a name or number with a generic placeholder before sharing a document externally.
Things to keep in mind
Find and replace works line by line, so it won't match text that spans across two lines. When replacing, the original text is covered with a white background and the new text is placed in its spot with roughly the same font and size — this works great on plain white pages, but may not blend perfectly on colored or shaded backgrounds. It's always worth reviewing the final result before sending it out.
Private from start to finish
Because find and replace runs entirely in your browser, your document never leaves your device while you search for or edit sensitive text. That makes the tool a good fit for contracts, financial records, and personal documents.
