Convert an Image to a Base64 Data URL for Free

Select an image to generate its Base64 Data URL for an embedding field or local test. Copy the entire result, including the data:image prefix, and compare the encoded length with your destination limit before using a large asset.

Encode PNG to Base64 Online for Free

Load a PNG image and copy its generated Base64 representation with the correct media type prefix. Check the full value after pasting it into your destination, because missing characters or a removed prefix can prevent the image from rendering.

Encode JPG to Base64 for Free

Choose a JPG file and generate the Data URL that represents its image bytes as text. Use a suitably small photo when embedding, since Base64 makes the data longer and does not compress the original JPEG file.
