Input & Output: The "Input" textarea is where you type, paste or upload your text. The truncated result is shown in the "Output" textarea, ready to copy or download.
Truncation side (default: right): Right-side truncation keeps the start of the text and removes characters from the end; left-side truncation keeps the end and removes characters from the start. The word "wildflowers" with 6 characters kept becomes "wildfl" from the right or "owers" from the left.
Characters to keep (default: 100): The number of characters left in the text. The sentence "Good morning to everyone" with 5 characters kept from the right becomes "Good ". If your text is already shorter than this number, it stays exactly as it is.
Line-by-line truncating (off by default): Shortens each line of the text separately to the same number of characters, so a list keeps its line structure.
Add truncation indicator (off by default): Appends characters such as "..." at the cut point - after the kept text for right-side truncation, before it for left-side. The indicator counts towards the length: with 15 characters to keep and "...", you get 12 characters plus the three dots. It is only added when the text is actually longer than the number.
Load an example: Loads a sample paragraph into the "Input" field and resets the options to their defaults so you can test the tool instantly.
Upload a file: Reads a text file from your device into the "Input" field - handy for truncating saved files.
Copy & Download: "Copy" puts the output on your clipboard for pasting elsewhere; "Download" saves it as a text file.
Truncate Text button: The central action - it cuts the input text using the chosen side, length, line-by-line and indicator options, and writes the result to the "Output" field.
Clear & Reset: Clears both textareas and resets the tool to its initial state.
