Convert Base64 strings to images instantly. Decode Base64 data URIs back to image files for download or use.
Base64 to Image conversion decodes Base64-encoded strings back into image files. This is the reverse process of image to Base64 conversion, allowing you to extract images from Base64 data URIs or Base64 strings. This is useful when you have Base64-encoded image data and need to convert it back to a usable image file format.
Our free Base64 to Image converter makes it easy to decode Base64 strings back to images. Simply paste your Base64 string or data URI, and the tool displays a preview and allows you to download the decoded image. The converter handles complete data URIs or raw Base64 strings, automatically detecting the image format and generating the appropriate file.
Converting Base64 back to images is useful in several scenarios. You might receive Base64-encoded images from APIs, need to extract images from HTML/CSS files, or want to decode images stored in databases or JSON responses. Base64 to image conversion allows you to recover the original image files from encoded data, making them usable as regular image files again.
This conversion is also helpful for debugging, testing, or when working with APIs that return Base64-encoded image data. By converting Base64 to images, you can save, edit, or use the images in standard image editing software or web applications that require file uploads rather than data URIs.
Base64 decoding reverses the Base64 encoding process, converting ASCII text back into binary image data. The decoder reads the Base64 string, converts each character back to its 6-bit value, combines these bits into bytes, and reconstructs the original binary image data. This binary data can then be saved as an image file in formats like PNG, JPG, GIF, or WebP.
Our tool handles both complete data URIs (format: data:image/[type];base64,[data]) and raw Base64 strings. When a data URI is provided, the tool extracts the image type and Base64 data automatically. For raw Base64 strings, the tool attempts to detect the format or defaults to PNG.
The conversion process involves several steps:
Our tool uses the browser's built-in Base64 decoding capabilities and creates data URIs for image display. The entire process happens client-side, ensuring your data remains private and conversion is fast.
Base64 image data URIs follow this format:
data:image/[type];base64,[base64-encoded-data]Our converter accepts:
data:image/png;base64,iVBORw0KG...iVBORw0KGgoAAAANSUhEUg...When a raw Base64 string is provided, the tool creates a data URI with PNG format. For best results, use complete data URIs that include the image type.
Base64 decoding uses the browser's built-in atob() function and data URI handling. The conversion process:
The tool processes Base64 strings entirely in the browser, ensuring privacy and speed. Very long Base64 strings may take longer to process or require more browser memory.
The converter supports all common image formats including PNG, JPG, GIF, WebP, BMP, and SVG. The format is detected from the data URI or defaults to PNG for raw Base64 strings.
Yes, the tool accepts raw Base64 strings. It will create a data URI with PNG format. For best results, include the complete data URI with the image type.
The tool validates Base64 format and image data. If the string is invalid or doesn't contain image data, an error message will be displayed.
Currently, the tool processes one Base64 string at a time. You can convert multiple images by processing them individually.
No, Base64 decoding doesn't affect image quality. The decoded image is identical to the original image before encoding.
