Base64 to Image Converter

Turn Base64 payloads into downloadable images without a backend. Processing stays on your device.

How to Use

  1. Paste a data URI or raw Base64 string.
  2. Preview the decoded image.
  3. Download as PNG or JPG.

Key Features & Privacy Advantage

  • All processing happens locally in your browser. Your files are never uploaded to a server.
  • Accepts data URIs or bare Base64.
  • Choose PNG or JPEG download format.
  • Validation errors for malformed input.

Technical Breakdown

APIs and emails often ship images as Base64. This tool normalizes a data URI or raw string, builds a Blob, previews via object URL, and can re-encode through canvas when you pick JPEG output.

Invalid characters, missing padding, or truncated strings produce explicit errors instead of a blank preview. Very large strings may stress memory — keep payloads reasonable.

Nothing is posted to a server, so debug dumps containing screenshots stay private on your machine.

Frequently Asked Questions

What input formats work?

Full data:image/...;base64,... URIs or raw Base64 of an image.

Do you store my paste?

No. All processing happens locally in your browser. Your files are never uploaded to a server.

Why PNG vs JPG?

PNG keeps transparency; JPG is smaller for photos but lossy and opaque.

Can I convert SVG data URIs?

If the browser can render the SVG, you can rasterize via download as PNG.
