About Image to Base64 Converter – Data URL Generator
Convert raster and vector images into RFC 2397 Data URLs or raw Base64 character strings directly inside your browser.
The image is decoded and processed locally in your browser; it is not uploaded to Navorika.
How to use this tool
- 1Select or drag and drop a JPG, PNG, WebP, GIF, or SVG image file.
- 2Choose between full Data URL format or raw Base64 string output.
- 3Optionally toggle RFC 2045 76-character line wrapping for email or documentation embedding.
- 4Copy the generated Base64 payload or download it as a .txt file.
Understanding the result
Base64 encoding expands raw binary data by approximately 33% due to 6-bit chunk mapping.
Data URLs can be embedded directly into HTML <img> tags or CSS background-image rules without additional HTTP requests.
Important limitations
- Base64 strings for large photos can reach several megabytes, which may bloat HTML or CSS payloads.
- Browser memory limits input file uploads to 25 MB.

Frequently asked questions
What is the difference between Base64 and Data URL?
A raw Base64 string contains only the encoded binary characters. A Data URL includes the MIME prefix (e.g. data:image/png;base64,) allowing browsers to render it directly as an image source.
Are my images uploaded to any server?
No. All encoding runs 100% locally in your web browser memory. Your files never leave your computer.
Can I use the Base64 output in HTML and CSS?
Yes. You can paste Data URLs into <img src="data:image/..."> or in CSS as background-image: url("data:image/...").
