Drop two files, then run a comparison. You get a similarity score, metadata check, and for text files a line-by-line diff. All processing stays in your browser.
You have two versions of a document, config, or script and need to see what changed. Version control, QA checks, and backup verification are the main uses. This tool runs in the browser so your data never leaves your device.
For text and JSON, you get a line-by-line diff with additions and removals highlighted. For binary files you get a similarity percentage and size or type differences; a full byte diff is not shown in the preview.
Very large files may slow the tab. Compare similar formats for meaningful results; mixing a text file with an image only gives size and type comparison. The diff is line-based for text, not word or character-level. For checksums and integrity, use a checksum validator.
Pair this with the File Duplicate Finder or File Metadata Extractor when you need to audit or document file sets.
