Image to Base64
Encode an image file as a Base64 data URI for an HTML or CSS asset. Copy the complete media-type prefix and encoded bytes, or download the text.
- Encode the selected image’s original bytes
- Include the image data-URI prefix
- Copy or download the encoded asset
Embed a small image asset
Choose the image and copy the resulting data URI. A compatible HTML image source or CSS image value can then contain the asset inline.
Keep the original encoding
This tool encodes the selected file rather than resizing or recompressing it. Convert the image first if you need a different format.
Account for the size increase
Base64 generally adds about one third to the byte representation, plus the prefix. Large photographs are usually better served as separate files.
Check the destination’s policy
Some editors and content-security policies reject data URIs. Confirm support where the asset will be used before embedding it.

No. The original bytes can be recovered from the encoded text.
No. Use Image Format Converter first; this tool changes representation, not the image format.
Usually a separate image file is more practical. Base64 adds roughly one third to the byte representation and makes the containing document larger. Reserve data URIs for small assets or self-contained examples, and resize or compress the source first when appropriate.
