How to use Image to Base64
- Choose a JPG, PNG, or WebP up to 8 MB.
- Select a complete data URL or just the Base64 characters.
- Copy the generated text or download it as a text file.
A closer look
Base64 represents the bytes of an image using text characters. A data URL adds the image type and a prefix so the string can be used in compatible documents or code. It does not improve quality or encrypt the image. Base64 is roughly one third larger than the original binary data, so embedding many large pictures can make documents or web pages slow.
A practical example
Convert a small PNG icon into a data URL for a test HTML document. The encoded text is larger than the original bytes, so a normal file is usually better for large images.
A useful tip
Choose Data URL when your destination asks for a value beginning with data:image/. Choose Base64 only when it specifically asks for raw Base64.
Good questions. Simple answers.
Does this change the image?
No. The original supported image bytes are encoded without recompression.
Is Base64 private or encrypted?
No. Anyone with the text can decode the image. Treat it like the original file.
