About Base64 to Image Converter – Decode Data URL to File

Decode Base64 character strings and RFC 2397 Data URLs back into viewable and downloadable image files entirely in your browser.

The image is decoded and processed locally in your browser; it is not uploaded to Navorika.

How to use this tool

  1. 1Paste a raw Base64 string or full Data URL into the input area.
  2. 2The converter automatically strips formatting whitespace and detects the underlying image MIME format.
  3. 3Preview the decoded image and review pixel dimensions and byte size.
  4. 4Download the image file with the correct extension (.png, .jpg, .webp, .gif, or .svg).

Understanding the result

Magic byte sniffing inspects the first few bytes to determine whether the payload is PNG, JPEG, GIF, WebP, or SVG.

Active scripts in decoded SVG vectors are detected and sandboxed to prevent script execution.

Important limitations

  • Corrupted or truncated Base64 strings missing essential byte segments cannot be rendered.
  • Decoded file size will be roughly 25-33% smaller than the Base64 character string length.

Frequently asked questions

Do I need to include the data:image prefix?

No. You can paste either a full Data URL or a raw Base64 string. The tool will automatically inspect the magic bytes to determine the format.

Can I decode SVG images safely?

Yes. SVG content is scanned for dangerous scripts and entity expansions. If active code is detected, interactive DOM rendering is disabled for security while safe download remains available.

Is processing performed on a server?

No. Decoding happens entirely within your web browser using client-side JavaScript.
