What This Tool Does
This tool converts every alphabetic character to lowercase in a single pass. It is ideal when imported content arrives in random caps from scans, legacy systems, or user submissions. The converter does not attempt grammar correction; it performs a faithful character-level transformation you can chain with title or sentence case tools afterward.

Frequently Asked Questions
Will lowercase affect accented letters?
Yes. Accented capitals like É become é while the accent remains.
Can I recover the original casing?
Use Clear and re-paste your source; the tool does not keep a casing history.
Does it lower case Turkish Ä° correctly?
Unicode lowercase rules apply; edge locale cases may need manual review.
Is batch conversion supported?
Paste as much text as you need—the entire block converts at once.
