Image to Base64 Converter

Encode a PNG, JPEG, WebP, or GIF image as a Base64 data URI entirely in your browser. A data URI can embed a small image directly in HTML, CSS, or a JSON fixture. Choose a supported local file to encode its bytes and MIME type together. Copy the result for development or testing, and keep in mind that Base64 text is larger than the original binary file. Select a supported image from your device, review the preview, and process a separate copy in your browser. Tool Fly does not upload the selected source file. Input is limited to 10 MB to avoid excessive browser memory use. Base64 is an encoding, not encryption or compression. Keep the original until you have checked the downloaded result at its intended size and in the applications where it will be used.
