By embedding images directly into HTML or CSS as Data URIs, you eliminate separate server requests for image files.
Base64 encoded images travel with your code, eliminating the need to manage separate image files and directories.
Email clients often block external images. Base64 encoded images are embedded directly in the email's HTML.
All modern browsers support Data URIs with Base64 encoded data. Use them in `img` src attributes or CSS backgrounds.
When images are embedded in your CSS or JavaScript files, they benefit from the same caching strategy as your code.
Your images remain accessible even if a CDN service is down. Base64 encoding ensures your web application is self-contained.
How to Use?
1.
Choose Mode: Select "Encode" to turn a file into text, or "Decode" to turn text back into a file.
2.
Provide Input:- For encoding, drag and drop your file(s) or click to select them. Pro users can encode multiple files at once.
- For decoding, paste the Base64 text into the text area and set a filename with the correct extension (e.g., `my-document.pdf`).
3.
Process Your Data: Click the "Encode" or "Decode" button. All operations are performed securely and instantly in your browser.
4.
Get Your Result: After encoding, you can preview, copy, or download the resulting Base64 string. After decoding, your file will be downloaded automatically.

Our Base64 encoder supports a wide range of file types, including images (JPG, PNG, GIF, WebP, SVG, BMP) and plain text files (TXT, HTML, CSS, JSON). Pro users can upload up to 20 files simultaneously. The tool is designed to handle everything from photos and graphics to code snippets and configuration files. Simply drag and drop your files or click to browse—the conversion happens instantly and safely in your browser.
Base64 is a standard method for encoding binary data (like images, documents, or any file) into a text-only format. This makes it possible to transmit data over channels that are designed to handle only plain text. A common use case is embedding images directly into HTML or CSS files as a "Data URI", which can sometimes improve loading performance for small images by reducing the number of server requests.
Yes. Your privacy is our priority. The entire encoding and decoding process happens locally on your own computer, right within your web browser. No files or data are ever sent to our or any third-party servers, ensuring your information remains completely private and secure.
A raw Base64 string contains only the file's data, not its metadata like name or type. You need to provide a filename with the correct file extension (e.g., `.jpg`, `.pdf`, `.txt`) so that your operating system and applications know how to open the decoded file correctly.
