Find differences between two text versions easily and instantly. Paste your text or upload files to identify automatically highlighted additions, removals, and modifications side-by-side without downloading any software.
Analyzing differences...
Type, paste, or upload the first text (or original file) in the left panel.
Type, paste, or upload the second text (or updated file) in the right panel.
Click "Compare Texts" to view the color-coded results showing added, removed, and modified lines.
Our tool currently supports uploading unformatted .txt documents for comparison. For documents like PDF, Word, or Excel, you can copy the text manually and paste it into the editor boxes.
No, your privacy is fully protected. All text comparisons are processed securely within your browser using JavaScript. We never upload, save, or store your text data on our servers.
The results use clear color-coding: Green highlighting indicates text that was added to the second version, Red highlighting with strikethrough shows text removed from the first version, and Yellow/Orange highlighting points out lines that were modified.
There is no strict hard limit, as the comparison happens in your browser. However, pasting extremely large text files (tens of thousands of lines) may cause your browser to slow down while rendering the diff view.
