Base64 to Image Decoder

Decode Base64 strings or data URIs into previewable image files with downloadable output and image metadata.

Quick samples

Base64 input

Paste a full data URI or raw Base64 string to decode it back into an image file.

Wrapped or multiline payloads are fine when whitespace stripping stays enabled.

The file extension is added automatically after the image type is detected.

Keep this on for wrapped Base64 copied from emails, logs, or formatted JSON.

Decoded image

Review the preview, confirm the detected image details, and download the recovered file.

No decoded image yet

Paste a Base64 image payload and run the decode to see the preview and download action.

About this tool

Base64 to Image Decoder turns a Base64 image payload or full data URI back into a previewable image file. Use it when an inline asset needs to become a real download again.

What it accepts

Paste a full data:image/...;base64,... value or the raw Base64 portion only.

Whitespace stripping helps when the payload was copied from a wrapped email, JSON block, or formatted log output.

info

Gotchas

Not every Base64 string represents an image. The tool only shows a preview when the decoded bytes describe a valid image.

The output filename is normalized automatically, and the file extension comes from the detected image type rather than the pasted text.
