How to use it
Drop an image here to get it as base64 text and a data URI, ready to copy — or paste base64 to turn it back into an image.
Base64 turns an image into plain text, so you can paste it straight into code — HTML, CSS, JSON, or an email — instead of linking to a separate file. Great for small icons.
To convert an image: drop it onto the Image → Base64 tab. You get a data URI (ready to use in HTML or CSS) and the plain base64 text, each with a copy button. Your image isn’t changed in any way.
To go back: paste base64 into the Base64 → Image tab and download the picture. If your text doesn’t start with “data:”, just tell it the image type.
Expect the text to be about a third bigger than the original file — that’s normal for base64.
FAQ
Does it change the image quality?
No. The image is copied exactly, byte for byte.
Why is the base64 text so long?
Base64 is about a third bigger than the original file. That’s the price of turning it into plain text.
My base64 doesn’t start with “data:”. Will it work?
Yes. Paste it into Base64 → Image and choose the image type from the menu.
How it worksFor the curious
Image → Base64 reads the file with the browser’s FileReader API directly into a data URI. There is no canvas re-encoding step, so the bytes are identical to the original.
Base64 represents binary data with 64 printable characters: every 3 bytes become 4 characters, which is the roughly 33% size increase.
Base64 → Image decodes the payload back into bytes and builds a downloadable file. A full data URI carries its MIME type; raw base64 has none, so the type must be chosen.
