The word counter gives you character and word counts in real time. The case converter handles upper, lower, title and sentence case in one click. The Lorem Ipsum generator creates placeholder text for design mockups in any length. Base64 encoding and decoding is essential for developers handling data in URLs, APIs or email attachments. The duplicate line remover cleans up lists and datasets, and the URL encoder/decoder converts special characters for safe use in web addresses.

Frequently Asked Questions

Base64 converts binary data into a text string using 64 printable characters. It is used to embed images in CSS, encode data in APIs and transmit binary content in text-only formats like email (MIME).
URL encoding (percent-encoding) replaces characters that are not safe in a URL — like spaces, ampersands and quotes — with % followed by their hex code. For example, a space becomes %20.
Title case capitalises the first letter of each major word. Common prepositions and articles (in, of, the, a) are typically left lowercase unless they start the title.
The tool compares each line of your text and removes exact duplicates, keeping only the first occurrence. Blank lines are also removed. Useful for cleaning up export lists, keyword lists and log files.
No — all text processing runs in your browser memory. There is no server-side limit. Very large texts (millions of characters) may slow down older devices.
