About Base64 to Image

Base64 to Image decodes Base64-encoded image strings back into viewable, downloadable image files. Paste a full data URL (data:image/...;base64,...) or just the raw Base64 portion, and the tool will detect the format, show a preview, and let you download the file.

This is the companion tool to Image to Base64 and is indispensable for developers who need to inspect or extract images from API responses, HTML source code, config files, or database records. Simply paste the encoded string — with or without the data URL prefix — and the tool instantly renders a visual preview.

The tool handles PNG, JPG, WEBP, GIF, SVG, and any format the browser natively supports. Format detection is automatic from the data URL prefix. Download the decoded image with one click.

Common Use Cases

  • Preview and download images from API response payloads
  • Extract embedded images from HTML source or JSON config files
  • Recover image files from Base64 strings in log files
  • Debug image encoding pipelines by visually verifying output
  • Convert data URIs from CSS files back to standalone images
  • Extract images embedded in exported database records

Troubleshooting

Pasting the string produces no image preview

Solution

Ensure the string starts with "data:image/" for a full data URI, or is a valid raw Base64 string without extra whitespace or line breaks.

Decoded image appears corrupted or shows only noise

Solution

The Base64 string may be incomplete or contain encoding errors. Verify the full string was copied without truncation.

Tool rejects the input string

Solution

Remove the "data:image/png;base64," prefix if it appears twice, or strip surrounding quotes that may have been copied along with the string.

Frequently Asked Questions

Do I need to include the data URL prefix?

No. You can paste just the raw Base64 string and the tool will handle it. The data URL prefix (data:image/...;base64,) is optional.

Which formats are supported?

PNG, JPG, WEBP, GIF, SVG, and any format that a browser can natively display.

What should I do if the preview shows a broken image?

First check that the Base64 string is complete and has no extra spaces or line breaks. If the string comes from a JSON file, make sure you copied only the value without surrounding quotes.

Can I paste a full data URL directly?

Yes. Paste the complete string including the data:image/...;base64, prefix and the tool will decode it automatically.

Is there a length limit on the Base64 input?

There is no hard limit. The practical limit is your browser memory. Strings representing images up to 10 MB decode reliably in modern browsers.

How is this different from the Image to Base64 tool?

Image to Base64 converts an image file into a Base64 string. Base64 to Image does the reverse — it converts a Base64 string back into a viewable and downloadable image file.

What should I do if the image preview is blank?

Check for invalid characters. Base64 strings must not contain spaces or line breaks. Try re-copying from the original source.

Can I paste a URL instead of a Base64 string?

No. This tool only accepts Base64 strings or data URIs. To load an image from a URL, download the image file first then use the Image to Base64 tool.
