Text Compare FAQs
What is a text diff tool?
A text diff tool compares two blocks of text and highlights what was added, removed, or changed. It is useful for reviewing document edits, comparing code versions, checking contract revisions, or spotting differences between two copies of the same content.
What is the difference between line and character diff?
Line diff compares text line by line and highlights entire lines that changed. Character diff compares at the character level and shows exactly which words or letters differ within a line. Use line diff for code or documents; use character diff for fine-grained edits.
Can I compare text side by side?
Yes. DozoTools Text Compare supports inline, side-by-side, and unified views. Side-by-side mode shows the original and modified text in two columns with matching changes highlighted. Unified view displays a single column in standard diff format.
Is my text sent to a server?
No. All comparison runs entirely in your browser. Your text is never uploaded, stored on DozoTools servers, or shared with third parties. You can paste sensitive content with confidence.
Can I download or copy the diff results?
Yes. Use the Copy button to copy the unified diff output to your clipboard, or Download to save it as a plain text file. You can also swap the original and modified text to reverse the comparison direction.
