Removing an emoji from a paper sent through WhatsApp without erasing the writings can be a bit tricky, as WhatsApp doesn't provide an editing feature for messages once they are sent. However, you can try a workaround by using a photo editing app or tool. Here's a step-by-step guide:


1. **Take a Screenshot:**

   - Open the conversation in WhatsApp containing the paper with the emoji.

   - Take a screenshot of the paper so that you have a static image to work with.


2. **Transfer the Image:**

   - Save the screenshot to your device's photo gallery or camera roll.


3. **Use a Photo Editing App:**

   - Open a photo editing app on your device. If you don't have one, you can use the default photo editing tools available on your phone.


4. **Edit the Image:**

   - Locate the image in the photo editing app.

   - Use the editing tools to cover or remove the emoji. You can try cropping, blurring, or using the brush tool to cover the emoji with the background color.


5. **Save the Edited Image:**

   - Save the edited image with a new name to avoid overwriting the original.


6. **Send the Edited Image:**

   - Share the edited image through WhatsApp or any other messaging platform.


Keep in mind that this method won't remove the emoji directly from the original message on WhatsApp. Instead, it provides you with an edited version of the image that you can share as needed. If the document is text-heavy, you may need to be precise in your editing to avoid covering any important information.


Additionally, some third-party apps or online tools might offer more advanced editing features. Always ensure that you are comfortable with the privacy and security implications of using third-party tools, and be cautious about sharing sensitive information.
