Frequently Asked Questions
Is my text sent to a server when I paste it?
No. All text processing happens entirely in your browser. Nothing you type or paste is transmitted over the network.
Is there a text size limit?
There is no enforced limit. Performance depends on your browser and device. Most tools handle documents up to several megabytes of text without issues.
What is the difference between a text diff and a file diff?
The Text Diff Checker compares two blocks of text pasted directly into the tool, highlighting added, removed, and changed lines. For comparing files, paste their contents into the two input areas.
How do I convert text to a URL slug?
Open the Slug Generator, paste or type your title, and the tool produces a lowercase, hyphenated URL slug instantly. It strips punctuation, collapses spaces, and handles special characters automatically.
Can I use regex to find and replace text?
Yes. The Regex Tester lets you write a regular expression, test it against a sample, and see all matches highlighted in real time.
What does HTML escape do?
HTML escaping converts characters like <, >, &, and " into their HTML entity equivalents (<, >, &, ") so they display correctly inside HTML without being parsed as markup.
How to convert text to uppercase or lowercase
Open the Case Converter, paste your text, and click the case you want: UPPERCASE, lowercase, Title Case, or Sentence case. The converted text is ready to copy instantly.
How to compare two blocks of text
Open the Text Diff Checker and paste the original text in the left panel and the revised text in the right panel. The tool highlights every addition, deletion, and change line by line so you can review exactly what changed.
How to sort lines alphabetically
Paste your list into the Sort Lines tool. Choose ascending (AāZ) or descending (ZāA), optionally enable case-insensitive sorting, and click Sort. The sorted list is ready to copy.
