How to Convert Base64 to Image: Complete Guide (2025)
Learn everything about decoding Base64 to images. This comprehensive guide covers what Base64 is, why decode, step-by-step conversion, and practical applications using ConvertifyTool's Free Base64 to Image Converter.
What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data (like images) as ASCII characters. It is commonly used to embed images in HTML, CSS, JSON, or transfer images in APIs and emails. To use these images in design or development, you often need to decode them back to standard image files.
Why Convert Base64 to Image?
- Extract images from code: Recover images embedded in HTML, CSS, or JSON.
- Download images from emails: Save images embedded in email templates.
- API and database recovery: Decode images from API responses or database exports.
- Documentation and markdown: Restore images from documentation or markdown files.
- Data recovery: Retrieve images from logs or data dumps.
How Base64 Decoding Works
Base64 decoding works by:
- Removing any data URL prefix (e.g.,
data:image/png;base64,) - Decoding the Base64 string back to binary image data
- Rendering the binary data as an image (PNG, JPG, etc.)

Best Practices for Decoding Base64
- Check the prefix: Remove
data:image/png;base64,or similar if present. - Choose the right format: PNG is lossless, JPG is smaller for photos.
