How do I make a single file in an S3 bucket publicly accessible?

Question

How do I make a single file in an S3 bucket publicly accessible?
I'm new to AWS and using S3 for image storage on a basic website. I don’t want to make the entire bucket public—just one file. What are the exact steps to do this safely?

Hi, please try the following. 
 
**First, ensure bucket settings allow public access:**
Go to S3 bucket
Click on "Permissions" tab
Under "Block public access", make sure "Block public access to buckets and objects granted through new public bucket or access point policies" is OFF
Also ensure "Block public access to buckets and objects granted through any access control lists (ACLs)" is OFF
Make the object public:

**Select the file in S3**
Click "Actions" dropdown
Select "Make public using ACL"
Confirm the action

**Verify access:**
Click on the object
Copy the "Object URL"
Test in a new browser window

**Important Security Note: Only make objects public if absolutely necessary. Consider using pre-signed URLs for temporary access or Amazon CloudFront for content delivery instead of making objects directly public.**
