Yes. Every conversion is free with no account, watermark, or usage limit. - Is this text converter secure? Yes. Files are processed locally in your browser. Nothing is uploaded to a server, so your text stays on your device. - What does normalize line endings do? It standardizes how lines break in a text file. Windows often uses CRLF (carriage return + line feed) while Unix and macOS use LF. Normalizing helps files display and diff correctly across systems. - What is the difference between CRLF and LF? CRLF uses two characters (\r\n) at the end of each line; LF uses one (\n). Mixing styles in one file can cause extra blank lines or odd behavior in editors and scripts. - Does the converter work on mobile? Yes. It runs in modern mobile browsers that support HTML5 and JavaScript. Very large files may be slower on mobile devices. - What is the maximum file size? Each file can be up to about 50 MB. If a file is too large, you will see a clear error message asking you to use a smaller file. - Why did my conversion fail? Common causes are a non-text file, corrupted data, or exceeding the size limit.
