Compare two text files, or paste two versions of a text, and see exactly which lines were added, removed or changed. It is built for large files such as logs, exports and configuration files. The comparison runs in your browser, so your files are never uploaded.
Original
Changed
Your text stays on this device. The comparison is done by your browser and nothing is sent to FitOnear.
How to use it
- Put the original text on the left and the changed text on the right. Paste it, choose a file, or drop a file on the box.
- Press Compare. Removed lines are shown in red, added lines in green, and the words that changed inside a line are marked.
- Use Show to see only the changes or the whole file, and Full screen for wide files.
- Download or copy the differences as a standard .diff file to share or keep.
Good to know
- Private: the comparison happens in your browser. Your files are not uploaded or stored.
- Large files: it compares line by line and is designed for files with hundreds of thousands of lines. The limit is your device's memory.
- Text only: it works with plain text such as .txt, .log, .csv, .json, .xml and source code, not Word or PDF documents.
- Options: ignore spacing or upper/lower case when those differences do not matter.
