About Base64 to Image Converter
The Base64 to Image Converter is a free online tool that decodes Base64 encoded strings back into viewable and downloadable images. Base64 encoding is commonly used to embed images directly in HTML documents, CSS stylesheets, JSON data, and email attachments. This tool reverses that process, allowing you to extract and save the original image file.
When you paste a Base64 string, the tool automatically detects whether it includes a data URL prefix (like data:image/png;base64,) or is raw Base64 data. For data URLs, the image format is detected automatically from the MIME type. For raw Base64 input, you can manually select the correct format (PNG, JPEG, WebP, or GIF) to ensure proper decoding.
The live preview feature lets you verify the image before downloading. You can see the detected format, image dimensions in pixels, and estimated file size. The download feature allows you to save the image with a custom filename while preserving the correct file extension based on the format.
All processing happens entirely in your browser using JavaScript and the Canvas API. Your Base64 data never leaves your device, ensuring complete privacy and security. This makes the tool ideal for handling sensitive images or working with confidential data.
