Compare two texts and highlight added, removed, and unchanged lines instantly.

كيفية استخدام مدقّق الفروقات

1

Paste original text

Enter the original or older version of the text in the left panel.

2

Paste modified text

Enter the new or updated version in the right panel.

3

Read the diff

Green lines are additions, red lines are removals. Unchanged lines are shown in the middle.

What is the Diff Checker?

A diff checker compares two pieces of text and highlights what changed between them: lines that were added, lines that were removed, and lines that stayed the same. Developers use it to review code changes, writers use it to compare drafts, and anyone can use it to spot the differences between two versions of a document.

Paste your original text on one side and the new version on the other. The tool aligns the two and color-codes every difference so you can see the changes at a glance instead of reading both versions line by line.

  • Compare two texts and highlight added and removed lines
  • Clear color coding for insertions, deletions, and unchanged lines
  • Works for code, prose, config files, and data
  • Handles large blocks of text smoothly
  • No formatting is changed, so whitespace differences are visible
  • Runs in your browser, so your text stays private

When a diff checker saves time

Reviewing a pull request, confirming what changed between two config files, checking which lines an editor altered in your article, comparing two exports of the same data, or finding the one line that broke a script. In all of these, scanning color-coded differences is far faster and more reliable than reading both versions and trying to spot changes by eye.

How to read the result

Lines only in the original are marked as removed, lines only in the new version are marked as added, and lines present in both are shown as unchanged for context. A changed line usually appears as a removal followed by an addition, since the old version went away and a new version took its place.

Tips for cleaner comparisons

If you only care about content and not formatting, normalize indentation before pasting. Comparing minified code is hard because everything is on one line, so format both sides first. For long files, comparing the relevant section rather than the whole file makes the differences much easier to follow.

الأسئلة الشائعة

What does a diff checker do?
It compares two texts and highlights the differences, marking which lines were added, removed, or left unchanged so you can review changes quickly.
Can I compare code with it?
Yes. It works well for source code, configuration files, JSON, and any plain text. Whitespace differences are preserved so you can see indentation changes.
Is my text uploaded anywhere?
No. The comparison happens in your browser. Nothing you paste is sent to a server, so it is safe for private or sensitive content.
Why is a changed line shown as both removed and added?
A line edit is represented as the old line being removed and the new line being added, because the diff tracks lines rather than individual characters within a line.
Can it handle large files?
Yes, it handles large blocks of text. For very long files, comparing only the relevant section makes the differences easier to read.
