Converting Base64 strings back to images is simple:
Base64 to Image conversion is the process of decoding a Base64-encoded string back into its original image format. Base64 encoding converts binary image data into ASCII text format, making it safe to transmit in text-based systems like JSON, XML, or HTML. Converting it back to an image file allows you to view, edit, or use the image normally.
Base64 is a binary-to-text encoding scheme that converts binary data (like images) into ASCII text format using 64 characters. It's commonly used to embed images in HTML, CSS, JSON, or transmit binary data through text-based systems.
Only if the Base64 string represents image data. Base64 can encode any binary data, not just images. If you try to decode a Base64 string that contains text, JSON, or other non-image data, it won't produce a valid image. The tool will show an error if the Base64 string doesn't contain valid image data.
The tool supports all common image formats including PNG, JPEG/JPG, WebP, and GIF. The format is automatically detected from the Base64 data. If the format can't be determined, the image will be saved as PNG.
No, you don't need to include the data URL prefix. The tool accepts both full data URLs (like 'data:image/png;base64,...') and raw Base64 strings. If you paste a raw Base64 string, the tool will automatically handle it.
Yes! All conversion happens entirely in your browser using JavaScript. Your Base64 strings are never sent to any server, stored anywhere, or seen by anyone else. Complete privacy guaranteed.
Common reasons include: invalid Base64 characters, corrupted data, or the Base64 string doesn't contain image data. Make sure your Base64 string is complete and valid. Try removing any whitespace or line breaks if present.
Currently, the tool processes one Base64 string at a time. For multiple images, convert them one by one. This ensures each conversion gets proper validation and error handling.
The tool can handle Base64 strings of reasonable size. Very large Base64 strings (over 10MB when decoded) may cause browser performance issues. For best results, keep Base64 strings under 5MB when decoded.
