Frequently asked questions
Is this text converter free?
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. Check the message below the converter for specific guidance, then try again or refresh the page.
