What is Base64?
Base64 represents binary image data as text so it can be embedded in HTML, CSS, JSON, or API requests.
When to use it
It is useful for small icons, email templates, prototypes, and self-contained documents.
Keep it practical
Base64 usually makes data larger than the original file, so regular image URLs are better for large assets.

What Is a Base64 Image Viewer?

A data URL includes a media type and encoding prefix such as data:image/png;base64, followed by the encoded image data. Paste the complete value to preview it. If you only have raw Base64, choose the matching image type in the viewer.

Frequently Asked Questions
What is a Base64 image viewer?
A Base64 image viewer decodes supported Base64 image data and displays the resulting image as a preview.
How do I view a Base64 image online?
Paste a supported Base64 string or image data URL into the viewer. The image preview and available image details appear in the browser.
What is the difference between a Base64 image string and a data URL?
A Base64 string contains encoded image data. A data URL also includes the media type and encoding prefix, for example data:image/png;base64,.
Can I preview a Base64 image from an API response?
Yes, if the response contains valid image data in a supported format. You may need to extract the Base64 string or data URL from the JSON response first.
Which Base64 image formats can I preview?
The viewer supports PNG, JPG, WebP, GIF, and SVG. The encoded data and MIME type must be valid for the image to display.
Why is my Base64 image not displaying?
Common causes include incomplete or invalid data, an incorrect MIME type, an unsupported format, or whitespace or other characters that do not belong in the encoded value.
Does Base64 encoding make images smaller?
No. Base64 encoding usually increases data size by roughly one-third. It changes how data is represented, not how much image information it contains.
Is my Base64 image data uploaded to a server?
No. The viewer decodes and previews the data in your browser; the Base64 content stays on your device.
