Frequently Asked Questions
What operations does the string tools offer?
It offers 20+ common string operations: UPPERCASE/lowercase/Capitalize/camelCase/snake_case conversion, line sort/dedupe/reverse/shuffle, character/word/line counting, Base64 encode/decode, URL encode/decode, HTML entity encode/decode, whitespace trimming/collapsing, line numbering, and empty line removal. All processing happens locally in your browser — no data is uploaded. Handles up to 100,000 lines.
Is my data safe? Will it be uploaded to a server?
Absolutely safe. All string processing happens entirely in your browser using pure JavaScript — no data ever leaves your device. Even sensitive text like passwords, API keys, or private data is completely secure. Data is automatically cleared when you close the page.
Can I process multiple lines of text at once?
Yes! The tool supports line-by-line processing: sort, dedupe, reverse, and shuffle operations work on individual lines. Simply paste multi-line text and apply operations in one click. For best browser performance, we recommend keeping it under 100,000 lines.
Which naming convention conversions are supported?
Common programming naming conventions are supported: camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, and Train-Case. Enter a string and convert it with one click — perfect for API development, database design, and code refactoring.
Is Base64 encoding secure?
Base64 encoding is performed entirely client-side using the browser's built-in btoa/atob functions (with TextEncoder for Unicode support). No data leaves your browser. Note that Base64 is encoding, not encryption — use it for data transport, not security. For encryption, use our AES encryption tool.
