How to convert uppercase to lowercase
Paste the ALL CAPS text
Drop your shouting or all-caps text into the box. Conversion happens live in your browser.
Choose lowercase (or UPPERCASE)
Pick lowercase to calm the text down, or UPPERCASE to push it the other way.
Copy and reuse
Tap copy and paste the cleaned-up text into your email, doc or post.
Why convert uppercase to lowercase?
Text pasted from PDFs, scanned documents, old systems or caps-lock typing often arrives in ALL CAPS, which reads as shouting and is harder to skim. An uppercase to lowercase converter fixes that in one step so you can drop the text into normal copy.
This tool flips letter case both ways — uppercase to lowercase and lowercase to UPPERCASE — but it does not guess where sentences start. If you want the first letter of each sentence capitalized again, use the sentence case converter afterwards.
Runs privately in your browser
The conversion is a simple, local string transform, so your text never leaves your device and you do not need an account. It also works offline once the page has loaded.
