Base64 to Image

Tool Overview

The Base64 to Image Converter instantly transforms base64 strings or full data URIs into high-quality images. It is perfect for debugging inline images, reviewing embedded assets, or recovering files that were exported as base64 text. All decoding happens locally in the browser, so your data never leaves your device.

Key Features

🔍 Smart Base64 Detection

• Accepts raw base64 strings or full data:image/...;base64, URIs
• Automatically detects the MIME type from the input
• Cleans whitespace, line breaks, and clipboard artifacts before decoding

🖼️ High-Fidelity Preview

• Real-time preview of the decoded image with accurate dimensions
• Displays MIME type, file size, and character count for auditing
• One-click download with a custom filename and correct extension

🛡️ Privacy-First Workflow

• 100% client-side decoding, no uploads or external APIs
• Ideal for sensitive assets such as inline logos or design deliverables
• Safe reset action removes generated object URLs from memory

How to Use

1. Paste a base64 string or data URI into the input panel
2. Optionally adjust the file name prior to export
3. Click Decode Image to render and validate the image
4. Download the file or copy the sanitized data URI for reuse

Practical Use Cases

• Front-end debugging: Inspect inline images embedded in HTML or CSS
• Email development: Validate base64 assets before sending campaigns
• Design handoffs: Extract inline previews from design system documentation
• Data recovery: Restore images copied from logs or JSON payloads

Troubleshooting Tips

• Make sure the base64 string is complete and has not been truncated
• Remove comments or metadata that appear before the data URI prefix
• If the image fails to preview, download it first to examine the binary in another viewer
• For very large assets, consider compressing or splitting the base64 content before decoding

FAQ

Does the converter support all image formats?

Yes. Any format supported by modern browsers (PNG, JPG, GIF, WebP, SVG, etc.) can be decoded as long as the base64 data is complete.

What if my string contains spaces or line breaks?

The converter strips whitespace automatically, so you can paste multi-line content without extra formatting.

Is my data uploaded anywhere?

No. All operations happen locally. Once you clear the tool or leave the page, object URLs are revoked and nothing is stored.

Can I copy the cleaned data URI?

Yes. After decoding you can copy the normalized data URI for reuse in CSS, HTML, or documentation.
