Text-Änderungsverfolgung — Freies Online-Werkzeug

Why compare text

When two versions of a document, a contract, a configuration file, or a block of code look almost identical, finding what changed by eye is slow and unreliable. A diff tool marks every insertion, deletion, and edit, so you see exactly what is different in seconds. This is essential for reviewing revisions, catching unintended changes, and verifying that a copy matches the original.

How differences are shown

The two texts are aligned and compared line by line, with added content marked one way and removed content another, so changes stand out clearly. Unchanged lines stay neutral, which keeps your attention on what matters. This visual highlighting turns a tedious manual check into a quick scan, even across long documents with scattered edits.

Common uses

Writers compare draft revisions, developers check code or config changes, lawyers review edited clauses, and editors verify that a correction was applied. Anywhere two versions of text exist, a diff confirms what changed and what stayed the same. It is also a fast way to prove that a pasted copy is identical to a source.

Private and local

Text Diff runs entirely in your browser. Both blocks of text are compared locally and are never uploaded or stored, so confidential documents and code stay private. The comparison is instant, no server is involved, and closing the tab clears the text from memory.
