Base64 image viewer

Turn a Base64 string back into an image.

The image preview appears when the input is valid.

About Base64 image viewer

Inspect an image that is embedded in text as Base64. A data URI includes a MIME type and an encoding prefix as well as the encoded bytes.

Steps, and limitations

How to use it

  1. Paste the image data URI or supported Base64 input.
  2. Run the preview and check any validation message.
  3. Inspect the image and download it if needed.

Things to know

  • Declaring a MIME type does not make arbitrary bytes a valid image. Unsupported or unsafe inputs are rejected.
  • Large data URIs consume more memory than their visible text suggests.
