DiffNow: Free Online Diff Tool

Compare two text files or documents side by side with our free online diff tool, highlighting changes for an easy visual inspection.

What is DiffNow?

DiffNow is a free online difference checker that allows users to compare two text files, documents, folders, or websites to find the differences. It is very easy to use - you simply copy and paste or upload the original and revised versions into DiffNow's side-by-side comparison tool.

Once the texts are loaded, DiffNow scans them and highlights any additions, deletions, and changes in color, with a line connecting the related sections. This visual representation makes it very simple to identify exactly what is different between the two versions. You can also switch between different comparison modes like Word, Character, and Line mode for more granular analysis.

DiffNow runs entirely in the browser, so there's no software to download or install. It can compare plain text, code, Word docs, PDFs, and more. All file formats are supported. The tool is completely free and there are no annoying ads or signups. DiffNow is great for spotting changes in revisions of documents, reviewing website changes, analyzing source code diffs, and more.
