Paste raw Base64 or a data URI, preview safe image MIME types and download the decoded image from a local Blob.
निजी स्थानीय प्रसंस्करण
The browser does the work. Convertr does not receive image files, Base64 strings, filenames or decoded previews.
अक्सर पूछे जाने वाले प्रश्न
Are my images uploaded when I convert them to Base64?
No. The converter uses FileReader, Blob, and object URLs in your browser. Image files and Base64 strings are not uploaded to Convertr servers.
Can I decode Base64 back to an image?
Yes. Paste a raw Base64 string or a data URI, choose the MIME type if needed, preview the decoded image, and download it locally.
Should I use Base64 for large images?
Usually no. Base64 makes files larger and can slow pages down. It is best for small icons, placeholders, test fixtures, and quick developer snippets.
