"Upload an image" comes up in two very different QR tasks, and it helps to know which you're doing. You might upload an image to read a code that's inside it, or upload an image to place a logo inside a code you're creating. Here's how each works.
Uploading to Read a Code
If you have a picture containing a QR code, uploading it to a reader lets the tool detect the code and reveal its link, no camera needed. This is the route for screenshots, downloads, or any code that exists only as a file.
Uploading to Brand a Code
If you're creating a code, you can upload a logo or image to sit in the center for branding. An image QR maker places it within safe limits so the code stays scannable while carrying your visual identity.
The Key Difference
Reading takes a code-containing image and gives you data out. Branding takes a plain logo and puts it into a code you're building. One extracts information; the other adds decoration. Knowing which you need points you to the right tool instantly.
Tips for Both
For reading, upload the clearest, most complete image of the code. For branding, use a simple, high-contrast logo at a modest size, and always test the finished code before printing. Clean inputs give clean results in both cases.
