Questions answered
Image to Base64 FAQ
Does converting an image to Base64 upload the image?
No. FileReader creates the Base64 string inside your browser, so the image is not transmitted to a server.
Why is a Base64 string larger than the image?
Base64 encodes binary data as text, which normally increases the data size. Use Base64 only where an inline data URI is appropriate.
Can I copy the generated Base64 value?
Yes. The result includes a copy action and a downloadable text file.
