About Text Compare
ToolsPivot's Text Compare is a free online diff tool that finds every difference between two texts by comparing them line by line, then word by word inside each changed line, and highlighting additions, deletions, and changes with color coding. You can paste text, open a file (.doc, .docx, .pdf, .txt), or load a webpage URL into either box, all without creating an account or installing software.
Spot every difference between two texts
Text Compare accepts two inputs and runs them through a diff algorithm to flag every spot where they don't match. The results show up with green highlighting for added text and red for removed text. Unchanged content stays unmarked so your eye goes straight to what matters.
Three Input Methods: Open a .doc, .docx, .pdf, or .txt file, load a webpage URL for automatic content extraction, or copy and paste raw text into either box.
Word-Level Detection: Changed lines are compared again word by word, so a swapped word inside an edited sentence is marked on its own instead of the whole line turning red.
Color-Coded Output: Green marks text that was added in the second version. Red marks text removed from the original. Unmarked text is identical in both versions. A summary above the result counts added, removed, and changed lines and shows how similar the two texts are as a percentage.
Side-by-Side or Inline Display: Both texts appear in parallel columns, with matching lines kept level, or switch to Inline to read the changes as one list. Tick "Only changed lines" to fold away long stretches that didn't change.
Line Numbering: Each line keeps its number from the original and the changed text. Useful when you're discussing edits with a collaborator and need to point to a specific spot.
URL Comparison: Enter a webpage URL in either box and the tool pulls the page's text into it. Great for checking whether live web copy matches your approved draft, or for comparing two competing pages side by side.
Browser-Based Processing: The comparison itself runs in your browser using JavaScript. Pasted text and .txt files never leave your device. Word and PDF files, and web pages, are read on our server only to pull out their text.
How to compare two texts
Open the tool: Go to the Text Compare page on ToolsPivot. No account or login needed.
Add your first text: Choose one of three input options for the "First Value" panel. Upload a file, enter a URL, or paste text directly.
Add your second text: Do the same for the "Second Value" panel using any of the three input methods.
Click Compare Text: The tool processes both inputs through its diff algorithm and displays results below.
Review the differences: Scan the color-coded output. Green text was added, red text was removed, and unmarked text stayed the same between versions.
What the red and green highlights mean
The output can look overwhelming at first, especially for long documents. Here's how to read it quickly.
Start by scanning for red blocks. These are deletions: text that existed in your first input but is missing from the second. If you're reviewing edits from a collaborator, red sections tell you what they cut. Check each one to make sure the deletion was intentional.
Green blocks are the opposite. They represent additions in the second text that weren't in the first. If you're tracking revisions on a contract or article, green sections show you exactly what new content was introduced.
White (unmarked) text is identical in both inputs. You can skim past these sections unless you want to verify that specific passages survived editing unchanged. For code comparisons, pay extra attention to small green or red highlights inside otherwise white blocks. A single changed variable name or misplaced bracket is easy to overlook but can break an entire script. Tick Ignore spaces when only the indentation changed, so the real edits stand out.
File, URL or paste input, with no sign-up
Three Ways to Input: File, web address and paste input all work in the same box, so you can set a Word document against a live webpage without converting or copying anything first.
Zero Friction: No registration and no download. Each box holds up to 300,000 characters, which covers most contracts and long articles. Paste your text and get results in seconds. That's the entire workflow.
Catches What You Miss: Proofreading research shows people miss a real share of errors: about 30% of wrong-word typos slip past careful readers. Automated comparison marks every changed line, including small edits humans consistently overlook.
Private by Default: The comparison runs in your browser. Unlike tools like Copyleaks or Draftable that send your text to a server, ToolsPivot keeps pasted text on your device. That matters when you're comparing NDAs, medical records, or proprietary code. Files in Word or PDF format are the exception: they're read on our server to extract the text.
Works With Any Text Format: Paste raw text from Google Docs, open a .docx from Microsoft Word, or pull content from a URL. The tool handles the conversion so you don't have to. Run a quick word count on both versions afterward to spot length changes fast.
Instant Speed: Most documents are compared the moment you press Compare text. Even long legal contracts or full-length articles get compared almost instantly.
Mobile Friendly: Works on any phone or tablet browser. Compare texts from a client email on the go without needing a laptop.
People who check text for changes
Text comparison isn't just for developers running diffs on code branches (though it works great for that too). Here are the groups that get the most value from it.
Writers and editors
An editor sends back a "lightly edited" 3,000-word article. How lightly? Paste the original and edited versions side by side, and you'll see every change in seconds. No more reading two documents line by line trying to spot what moved. Writers working with multiple clients can also compare published web content against submitted drafts by using the URL input for the live page and pasting the original draft. If you're cleaning up repetitive phrases during the editing process, the duplicate line remover handles that in one click.
Developers
Quick code diffs without opening a terminal. Paste two versions of a config file, a CSS stylesheet, or a JavaScript function to spot exactly what changed. It won't replace Git for version control, but for one-off comparisons or reviewing someone else's code snippet, it's faster than setting up a repo. Ignore case and Ignore spaces help when a formatter changed the layout but not the logic.
Legal and compliance teams
Contract redlining is standard practice, but not every counterparty tracks their changes properly. Upload the original contract and the returned version to confirm nothing was altered outside the agreed revisions. This is especially important for non-disclosure agreements where a single added clause can change liability. For teams handling multilingual contracts, pair this with the paraphrasing tool to verify meaning consistency across translated versions.
SEO professionals
Compare on-page content before and after a site update to make sure nothing was accidentally removed during a CMS migration. Enter two URLs and the tool pulls the page content automatically. You can also check whether guest post editors changed your meta descriptions or anchor text after you submitted the piece.
Students and academics
Compare your final paper against the last proofread version to make sure no content was lost during formatting or file conversion. Run the comparison, then check grammar and readability scores on the final version before submitting.

The biggest advantage ToolsPivot holds here is the combination of three input methods in one box plus in-browser comparison of pasted text. Many free tools send whatever you paste to their servers. Here, pasted text and .txt files are compared in your browser; only Word, PDF and web-page text goes to our server to pull the text out. Paid tools like Beyond Compare offer file support but require installation and a license.
Frequently asked questions
The tool opens .doc, .docx, .pdf, and .txt files. Word and PDF files can be up to 500 KB. You can also enter any webpage URL to pull its text content automatically, or paste raw text from any source including Google Docs, email clients, and code editors.
Mostly. The tool first lines up matching lines, then compares each edited line word by word, so a changed word is highlighted inside the line and you don't have to hunt for it. A very short line, or one that was rewritten, shows as removed and added in full instead. Tick Ignore case or Ignore spaces when those differences don't matter to you.
Pasted text doesn't. The comparison runs locally in your browser using JavaScript, so pasted content and .txt files stay on your device. Word and PDF files, and web pages you load by URL, go through our server once so their text can be extracted. For confidential documents, paste the text instead of uploading the file.
Each box holds up to 300,000 characters, and Word or PDF files can be up to 500 KB. That covers most contracts, articles, and code files. For longer documents, compare them in sections.
Yes. Open a .docx file in one box and load the webpage in the other. The tool extracts the text from both and runs the comparison. Ideal for checking whether published web content matches your approved document.
Green highlighting marks text that appears in the second input but not the first (additions). Red marks text in the first input that's missing from the second (deletions). Everything unmarked is identical between both versions.
A plagiarism checker searches the web and published sources for text that matches yours. Text Compare only compares the two specific documents you provide. Use the plagiarism checker when you want to verify originality across the web. Use Text Compare when you want to find exact differences between two known versions of a document.
It handles code well for quick diffs. Paste two versions of a function or config file and the differences get highlighted just like plain text, with line numbers on both sides. It doesn't color the syntax or merge changes, so for deeper code work use the diff in Git or your code editor.
The tool compares two inputs per session. For multi-document comparison, run separate comparisons between each pair. Compare version 1 against version 2, then version 2 against version 3, and so on.
The comparison works on plain text content only. Bold, italic, font sizes, and other formatting don't transfer. The tool focuses on the actual words and characters, which is what matters for content accuracy checks.
Yes, free with no sign-up, no trial period, and no premium tier. Pasted text can be compared as often as you like. Opening Word or PDF files and loading web pages has a daily allowance of 100 per visitor. Run your comparison, then check line counts or text case formatting on the result using other free ToolsPivot tools.
