Why Use PixConvert Diff Checker

Fast, private text comparison with no file uploads.

Line-by-Line Diff

Myers diff algorithm highlights exactly which lines were added, removed, or unchanged.

Split & Inline Views

Side-by-side split view for context, inline view for compact reading. Toggle with one click.

Change Statistics

Added, removed, and unchanged line counts shown at a glance above the diff output.

100% Private

All diffing runs in your browser. Source code, API responses, and private documents stay local.

Any Text Format

Compare code, prose, JSON, YAML, CSV, logs — anything text-based. No format restrictions.

Copy Diff Output

Copy the diff as a unified patch or plain summary with one click.

When to Use a Diff Checker

Diff is the universal tool for change review.

Code Review

Compare code snippets or config changes before committing to a PR.

  • Spot unintended changes
  • Review config diffs
  • Compare algorithm versions

Document Comparison

Find differences between contract versions, API docs, or translated strings.

  • Compare document revisions
  • Diff translation files
  • Verify API schema changes

Log Analysis

Diff server logs from two time periods to isolate new errors or behavioral changes.

  • Compare log snapshots
  • Find new error patterns
  • Detect config drift

How to Compare Two Texts

1

Paste your original text in the left panel and the modified text in the right panel.

2

Click Compare. Added lines are highlighted green, removed lines red. Switch between split and inline views.

3

Toggle whitespace and case sensitivity to ignore noise — only meaningful changes show up in the diff.

Frequently Asked Questions

Text diffing explained.

What diff algorithm does this use?

This tool uses the Myers diff algorithm via the diff library — the same algorithm used by Git. It produces the minimal edit script (fewest insertions and deletions) needed to transform the original into the modified text.

Is my text safe to paste here?

Yes. All diffing runs entirely in your browser using JavaScript. Your text never leaves your device. This is safe for source code, API keys, private documents, and proprietary content.

Can I compare binary files?

No. This tool compares plain text. Binary files (images, PDFs, executables) should be compared with specialized binary diff tools.

What's the difference between split and inline view?

Split view shows original and modified side-by-side, making it easy to see context around changes. Inline view shows all changes in a single column — additions and deletions interleaved — useful for compact review of large diffs.

Can I ignore whitespace differences?

Whitespace-only changes are currently shown as regular changes. If you want to ignore trailing spaces, normalize your input before pasting — trim lines in a text editor, or use the Regex Tester to strip whitespace.
