Base64 to Image

About Base64 to Image

Decode a pasted image data URL back into a downloadable image file, after validating its MIME type and Base64 payload locally.

What the result contains

A decoded image file created from a complete image data URL after local validation.

Supported formats

• PLAIN
• TXT

How to use Base64 to Image

1. Paste the complete data:image/...;base64,... value.
2. Run the decode and preview the reconstructed image.
3. Remove stray quotes or whitespace if the value is rejected.
4. Download the decoded image file.

Check your result before using it

Open the generated image and compare its dimensions and appearance with the expected source. A valid Base64 string can contain something other than image bytes, and a declared MIME type does not prove that the contents match. If decoding fails, check for missing characters or an accidentally copied quotation mark. Do not publish the source string if the image itself is confidential: the string contains the image data.

When to use Base64 to Image

• Preview an image data URL found in code before trusting it
• Recover a downloadable image from a data URL stored in a config file
• Check that a generated Base64 payload decodes to the expected picture

Important limitations

• The input must include a supported image MIME type and a valid Base64 payload.
• Decoding does not prove that the source is trustworthy or free of misleading visual content.
