About Base64 to Image Converter
Decode Base64 strings back to images with our Base64 to image converter. Base64 encoding is commonly used to embed images in HTML, CSS, JSON, or transmit images as text. Our tool reverses this process, converting Base64-encoded image strings back to viewable, downloadable image files. Essential for developers extracting images from data URIs, API responses, or JSON payloads, designers recovering images from code, and anyone working with Base64-encoded visual content. Supports all common image formats including PNG, JPG, GIF, WebP, and SVG. Features instant preview of decoded images, download in original or converted formats, batch processing for multiple Base64 strings, and automatic format detection. All decoding happens in your browser for privacy and speed - no server uploads required.
Key Features
All Image Format Support
Decode Base64 to PNG, JPG, GIF, WebP, BMP, SVG, and more. Automatically detects original image format from Base64 data.
Instant Preview
See decoded image immediately before downloading. Verify correct decoding and image integrity visually.
Format Conversion
Download in original format or convert to different format. Convert PNG to JPG, GIF to PNG, etc. during the decoding process.
Data URI Handling
Accepts full data URIs (data:image/png;base64,...) or just the Base64 string. Automatically extracts image data from URI format.
Batch Decoding
Decode multiple Base64 images at once. Perfect for extracting images from JSON arrays or multiple data URIs.
Browser-Based Processing
All decoding in your browser - no uploads to servers. Complete privacy for sensitive images.
How to Use Base64 to Image Converter
Paste Base64 String
Paste your Base64 string or complete data URI (data:image/png;base64,...) in the input field. Both formats are accepted.
Automatic Detection
The tool automatically detects and decodes the image format. It identifies PNG, JPG, GIF, WebP, and other formats from the Base64 data.
Preview Image
View the decoded image preview immediately to verify the decoding was successful and the image displays correctly.
Choose Format
Choose download format - keep the original format or convert to a different format (e.g., PNG to JPG).
Download Image
Click download to save the image to your device in the selected format. The image is ready for use in any application.
Batch Process
For multiple images, paste all Base64 strings and use batch processing to decode and download all images at once.
Frequently Asked Questions
What is Base64 image encoding?
Base64 encoding converts binary image data into ASCII text. This allows images to be embedded directly in HTML, CSS, JSON, or any text-based format. Data URIs like 'data:image/png;base64,iVBORw0KG...' contain Base64-encoded images.
Why would images be Base64-encoded?
For embedding small images inline in HTML/CSS to reduce HTTP requests, transmitting images in JSON APIs, storing images in text-based databases or formats, and ensuring images work in email HTML without external references.
Can all Base64 strings be decoded to images?
No. Only Base64 strings that actually represent image data will decode to valid images. Random Base64 or Base64 encoding other data types won't produce viewable images.
How do I know if a Base64 string is an image?
Data URIs include the MIME type: 'data:image/png;base64' indicates PNG image. Look for 'image/' in the prefix. For standalone Base64, you'll need to try decoding - valid image data will produce a viewable image.
What's the difference between PNG and JPG in Base64?
The format is embedded in the data. data:image/png creates PNG, data:image/jpeg creates JPG. The actual Base64 string encodes the image in its original format. Our tool detects format automatically.
Can I convert the decoded image to a different format?
Yes! Our tool allows downloading in different formats. Decode a Base64 PNG and download as JPG, or vice versa. This is useful for format optimization.
Is there a size limit for Base64 images?
Practical limits exist. Very large Base64 strings (10MB+ of text) may cause browser slowdowns. For small to medium images (under 1-2MB original), Base64 decoding works perfectly.
Why won't my Base64 string decode?
Common issues: invalid Base64 characters, incomplete string (truncated), incorrect format (not actually image data), or corrupted encoding. Verify the Base64 is complete and actually represents an image.
Use Cases
- Extracting Images from APIs: Many APIs return images as Base64 in JSON responses. Decode these strings to save actual image files for use in applications or documentation.
- Recovering Images from Code: Extract images embedded in HTML, CSS, or JavaScript as data URIs. Convert inline images back to separate files for organization or editing.
- Email and Document Processing: Decode images embedded in email HTML or document exports. Extract attachments that were Base64-encoded for transmission.
- Testing and Development: Verify Base64-encoded images during development. Test that image encoding/decoding works correctly by visually checking decoded output.
- Data Recovery: Recover images from backups, logs, or data dumps where images were stored as Base64 strings instead of files.
