Question 1

What is a text diff checker?

Accepted Answer

A text diff checker is a tool that compares two pieces of text and highlights the differences between them. It shows what has been added, removed, or changed, making it easy to spot differences between document versions, code revisions, or any two text inputs.

Question 2

Is my text data private?

Accepted Answer

Yes, completely. My Text Compare processes all text entirely in your browser using JavaScript. No text data is ever sent to any server. You can verify this by opening your browser's Network tab — you'll see zero requests during comparison.

Question 3

What comparison modes are supported?

Accepted Answer

My Text Compare supports three comparison modes: character-level (highlights individual character differences), word-level (highlights changed words within lines), and line-level (highlights entire changed lines). You can also toggle "ignore whitespace" and "ignore case" options.

Question 4

Can I compare code files?

Accepted Answer

Yes. You can paste or drag-and-drop any text-based file including source code (.js, .ts, .py, .java, etc.), JSON, XML, CSV, Markdown, HTML, CSS, and more. The tool preserves formatting and supports line-level comparison ideal for code review.

Question 5

Is there a file size limit?

Accepted Answer

There is no hard file size limit. For very large texts (over 10,000 lines), the tool uses a Web Worker to keep the interface responsive. Performance depends on your device's available memory, but most files up to several megabytes work fine.

Question 6

How do I share a diff result?

Accepted Answer

Click the "Share" button to generate a compressed URL containing your diff. The URL encodes both texts and comparison settings using LZ-string compression, so anyone with the link sees the exact same comparison. No server storage is needed.

Question 7

How can I compare two texts online?

Accepted Answer

You can compare two texts online using a web-based text diff tool like My Text Compare. Just paste or upload both texts into the tool, and it highlights the differences instantly — no software installation required. Because My Text Compare runs entirely in your browser, your text is never sent to any server, so the comparison is 100% private.

Question 8

How to compare two text files in notepad++?

Accepted Answer

Use the built-in Compare plugin in Notepad++. First install it by opening Notepad++, going to Plugins → Plugins Admin, searching for "Compare", and clicking Install. Then open both text files in Notepad++ and press Alt+D (or choose Plugins → Compare → Compare). The plugin displays the two files side by side with synchronized scrolling and highlights added, removed, and changed lines.

Question 9

What is compare and contrast text structure?

Accepted Answer

Compare and contrast is a text structure that examines the similarities and differences between two or more subjects, ideas, or concepts. Writers use this structure to analyze topics side by side, organizing information around what is shared versus what is unique, often pointing out the implications of those similarities and differences.

Question 10

Is online text compare safe?

Accepted Answer

Online text comparison is safe when you use a tool that processes all data locally in your browser. My Text Compare runs entirely client-side using JavaScript, so no text is ever transmitted to, stored on, or read by any server. You can verify this yourself by opening your browser's Network tab and confirming that zero network requests are made during a comparison.
