A collection of text manipulation tools: transform, clean, format, convert, and analyze your strings.
String utilities are a collection of text-processing functions that let you transform, clean, convert, encode, and analyze any piece of text without writing code. Instead of switching between several websites or opening a text editor, this single tool combines everyday operations such as changing case, stripping HTML tags, removing duplicate lines, escaping strings, and converting text between formats like Base64, hex, and binary.
Developers use these utilities to normalize user input before saving it to a database, writers use them to clean and reformat drafts, and anyone working with logs, CSV exports, or configuration files can quickly tidy up raw text. Because every operation runs in your browser, no data is uploaded and results appear instantly as you type.
Yes. Under the Convert section, you'll find buttons to convert text to binary, hex, and Base64, with reverse conversions available for each. The tool also supports URL encoding and decoding for web-safe text transmission.
Click the "Strip HTML Tags" button under the Clean section. It removes all HTML tags from your input, leaving only the plain text content. This is useful when you've copied text from a web page and want to remove formatting.
You can convert text to UPPERCASE, lowercase, Title Case, tOGGLE cASE, camelCase, snake_case, kebab-case, and Capitalize (first letter of each word). Simply click the desired transformation button under the Transform section.
Yes, the "Remove Duplicate Lines" button under the Clean section removes all duplicate lines, keeping only the first occurrence of each unique line. This is helpful when cleaning up lists or log files with repeated entries.
There is no hard limit. The tool processes text entirely in your browser, so the practical limit depends on your device's memory. The stats bar shows real-time character, word, line, and byte counts to help you keep track of your input size.
