Compare PDF Files

Compare two PDF or Word documents side by side: Compare PDF Files marks every changed word, with a redline and a report. No upload.

🧾 Compare PDF Files: see every change between two versions of a document Compare PDF Files shows what changed between two versions of the same document. Every added, removed and edited word is highlighted on both documents, side by side. It is a PDF comparison tool that runs on your computer, so contracts and reports never leave it. Check a Word draft against the signed copy. Then save the change report. 🚀 How to use Compare PDF Files 1. Click the toolbar icon to open a comparison tab. 2. Drop the original on the left, the new version on the right. 3. Step through the edits with N and P, or in the list. 4. Click Export report to save the comparison. 💡 Why compare pdf files with a tool Reading two versions line by line is slow, and one edited number in a long contract is easy to miss. This document comparison ignores line breaks and spacing. It also skips running headers and page numbers. A paragraph that wraps differently isn't flagged, and neither is a page break that moved, so only real edits remain. Unlike a compare PDF online service, it uploads nothing: both files are read in the tab. ⭐ Key features ① Side by side PDF view: both documents, edits marked in red and green ② Synchronized scrolling keeps the same text level on both sides ③ Redline: removed words struck through, added words underlined ④ Visual comparison: edited areas boxed, a PDF overlay, a slider or blink ⑤ Change report to save or print, with the full text or edits only 📝 Word documents, images and plain text Pick a .docx Word file on either side to compare Word documents with each other or with a PDF; the text is read on your computer, like the rest. Drop two pictures for an image comparison in the visual view. Paste text on both sides and it works as a text compare and diff checker, the same redline included. 👥 Who uses this PDF compare tool ➤ Lawyers: a contract redline between two drafts, ready to send ➤ Engineers: drawing revisions checked in the overlay, one page pair at a time ➤ Designers: artwork comparison of proofs before they go to print 📑 Document compare for long files A 300-page agreement is no problem: only the pages on screen are drawn, and a contract comparison with hundreds of edits takes well under a second once the text is read. Filter the list to numbers to see every changed amount and date, or search it. It is a doc compare you keep in Chrome, for any two documents you need to check. 🎨 When text isn't enough Logos, charts and stamps have no words to read, and neither do scanned pages. The Visual view pairs the pages by the text they share, so an inserted page doesn't shift the rest. Then it checks the page images pixel by pixel. Edited areas get a box, and a sensitivity setting keeps specks on scans quiet. The overlay shows ink only in the original in red and ink only in the new version in green. ✅ At a glance 🔹 No upload and no account 🔹 Opens password-protected documents 🔹 Ignores headers and page numbers 🔹 Two samples to try it first 🔒 Your files are read only in the extension's tab, on your computer. Nothing is uploaded or sent anywhere. There is no account and no analytics, and the documents are gone when you close the tab. The extension saves only your view settings. 📄 Works with - Exports from Word, Google Docs or LaTeX - Word files (.docx), PNG and JPG images - Contracts, invoices, reports and drawings 🎯 Keep Compare PDF Files pinned for every new draft: drop two versions, read the redline, send the report.

The edits appear at once, listed and highlighted on both documents. ❓ Are my files uploaded? 💡 No. It is a way to compare pdf files on your computer that sends nothing anywhere, so it works offline too. ❓ Is Compare PDF Files free? 💡 Yes, free, with no account and no limit on pages or files. ❓ Does it work with scanned documents? 💡 Scans have no text, so the text comparison finds nothing in them. The Visual view checks their page images and boxes what differs. ❓ Can it compare Word documents? 💡 Yes. A .docx file compares with another one or with a PDF, so you can check the signed copy against your draft. ❓ What is a redline? 💡 The new text with deleted words struck through and inserted words underlined, the way lawyers mark up a contract. The Redline view and the change report show it, like track changes in a PDF. ✨ compare pdf files: every change, side by side, on your computer
