This tool supports all common web image formats: JPEG, PNG, GIF, WebP, SVG, BMP, ICO, TIFF, AVIF, and HEIC/HEIF. Each format can be compressed before encoding to reduce the base64 output size. You can also resize images or convert between formats using the options above. Have questions? Check our FAQ or read the tutorial for step-by-step instructions and code examples.

Enable the Optimize image toggle and we will automatically optimize the image before encoding it. Base64 is an encoding algorithm that converts any characters, binary data, and even images or sound files into a readable string, which can be saved or transported over the network without data loss.

3 weeks ago - This Base64 string represents the entire image, which can now be viewed directly on your webpage without relying on an external file. Data Type: Specifies the MIME type of the file. For example, for PNG images, it’s data:image/png.

It's stuffed with goodies of all sorts and descriptions, but I guess that you'll be most interested in the libraries that read/write the image file format. The (current) link is https://github.com/digitickets/star-web-print/blob/master/Sample/js/StarWebPrintBuilder.js — from a very brief glimpse of the appropriate functions, my guess is that it's a simple 'raw' format with no encoding. Another hint comes from GitHub repository — there are plenty of examples there — where there is a rather large collection of BMP images.

Batch Processing: You can upload up to 20 files at once! You can use the base64 encoded string directly in your HTML <img> tag's src attribute using the data:image/... format.

July 30, 2026 - Base64 encoding is prevalent on ... digital image in text such as HTML and CSS. ... Base64 is widely used for sending e-mail attachments, because SMTP – in its original form – was designed to transport 7-bit ASCII characters only. Encoding an attachment as Base64 before sending, and then decoding when received, assures older SMTP servers correctly transmit messages with attached binary information. ...

January 15, 2024 - To manually convert an image, use a site like http://base64online.org/encode. Upload your image to the site and copy the text it returns. Here’s an HTML example using a tiny image from Wikipedia that was converted to Base64:

A conversion program for creating base64 encodings is available on our lesson page. With an ordinary image element, we set the src attribute value to the name of a file on the local file system or at a remote URL. This example uses a local image file of a small red "X" in a 9 by 9 pixel image.

<img src="data:image/png;base64, <copy string here>" alt="Cat"> Back to main.

Reach for this to cut an HTTP request for a small, rarely-changing image — an icon, a logo, a placeholder — by inlining it straight into HTML, CSS, or a JSON config, instead of linking a separate file. The trade-off is size: base64 turns every 3 bytes into 4 characters, so the encoded string runs about 33% larger than the original, and an inlined image can no longer be cached independently of the page around it.

May 18, 2026 - API payloads that must carry image data as text (e.g. sending a logo in a REST API response) ... Base64 encodes every 3 bytes of binary data into 4 ASCII characters.

October 23, 2017 - An image embedded directly into an HTML image tag As a programmer, it is easy to accept this random-looking ASCII string as the “Base64 encoded” abstraction and move on. To go from raw bytes to the Base64 encoding, however, is a straightforward process, and this post illustrates how we get there.
