Convert Case Tool

I'm often renaming images for my website or coding projects, and it used to be a boring process to manually adjust each filename. That’s why I created a convert case tool to streamline the task, with a few extra features to make it even easier.

Click here to visit my Case Convertor Tool, which I developed on the Cloudflare Workers platform.

Need to quickly convert UPPERCASE to lowercase, Title Case, or Sentence Case? My convert case tool can handle that, and it also lets you replace spaces with hyphens—essential for web uploads where spaces turn into '%20', making your files harder to manage and less user-friendly.

Simply enter your text above, choose the conversion type, and even remove special characters or add hyphens in one go. Click "convert", and you'll see the result instantly in the box below.

So far I have edited this so that it is perfect for renaming large batches of image names at a time, and with the option of adding a file extension on if needed. If you apply the .jpg extension and then select the .png extension, the extensions then switch.

I’d love to hear your feedback! If you have suggestions for features that would make this converter tool even more useful, feel free to share them in the comments below. I’ll do my best to add in your ideas.
