About this tool
Preview Base64 image payloads when debugging data URLs, copied API responses, or inline assets without writing a separate decode script.
Base64 Image Decoder is useful when an encoded image string needs to become a visible preview before you trust it. It helps with debugging API payloads, data URIs, uploads, and exported assets where the question is whether the Base64 actually represents the image you expect.
- Supports full data URLs or raw Base64 strings.
- Shows the decoded image in a browser preview immediately.
- Lets you inspect mime type and file size before downloading.
How to use Base64 Image
Paste the Base64 image string, preview the decoded image, and then download or reuse it only after confirming the result is correct. If the preview fails, check whether the string includes a valid data URI prefix or whether the copied payload was truncated during transfer.
