Compare Two Texts Online
Paste two versions of a text and see what was removed and what was added. The comparison runs right in your browser: your text is not sent anywhere. Free, no ads, no sign-up.
Paste text into both fields — the differences will appear here.
How to use it
Paste the original text in the left box and the changed text in the right box.
Choose how precise the comparison should be: by word, by character, or by line.
The result appears below: removed text is highlighted in red, added text in green, with a change counter above it.
Features
Three levels of precision
By word for ordinary text, by character when every letter and comma matters, and by line for code, lists, and configuration files.
Works for code
A monospaced font, with spaces and line breaks kept exactly as they are. HTML tags are shown as text rather than rendered as markup.
Your text stays with you
Your browser does the comparing. What you paste is not sent to a server and is not stored anywhere, so you can safely compare contracts and work documents.
Change counter
Above the result you can see how many characters were added and how many were removed. If the texts are identical, the tool says so plainly.
Questions and answers
Is my text sent to a server?
No. The comparison runs in your browser; the texts are not sent over the network and are not stored.
What is the difference between the comparison modes?
“By word” highlights whole changed words and works best for ordinary text. “By character” shows differences down to a single letter, which helps when hunting for typos. “By line” compares entire lines and is the best fit for code.
Can I compare code, JSON, and config files?
Yes. Indentation and line breaks are preserved, and tags and special characters are shown as text. For code, “By line” mode is the most convenient.
Is the comparison case- and whitespace-sensitive?
Yes, the comparison is exact: “Word” and “word” count as different, and an extra space or line break also shows up as a difference.
Is there a limit on text size?
There is no hard limit. If the texts are large and differ a lot, the tool automatically switches to a coarser comparison — by word or by line — so the page does not freeze.
Need a custom service or work on your website?
We built these tools ourselves. We build websites, client dashboards, and internal business services the same way — and take over support of ones that are already running.
