How It Works
Our platform simplifies Base64 conversion into three straightforward steps. Everything is processed in your browser for maximum security and speed.
Upload Your File
Drag and drop your file into the designated area or click to browse your computer. We support a wide range of file types, including images (JPEG, PNG, GIF) and documents (PDF).
Edit & Customize (Optional)
For images, you can use our built-in editor to crop, resize, and adjust settings like brightness and contrast. For other files, you can proceed directly to conversion. This step is completely optional.
Copy or Download
Once the conversion is complete, you can copy the Base64 string to your clipboard with a single click. If you are decoding a Base64 string, a download link for the original file will be provided.
What is Base64 Encoding?
Base64 is a popular encoding method that converts binary data (like images, documents, or any computer file) into text format. Our Base64 converter tool makes it easy to encode and decode Base64 data online. This Base64 encoding process is essential when you need to transmit binary data through text-only protocols.
With our free Base64 encoder, you can embed Base64-encoded images directly into HTML or CSS files, reducing HTTP requests and improving performance. Our Base64 decoder lets you convert Base64 strings back to their original files. All Base64 conversion happens securely in your browser.
How Base64 Works
Understanding Base64 encoding in simple terms with visual examples
Try Interactive Demo →1The Problem
Computers store data as binary (1s and 0s), but some systems only handle text. How do you send a photo through email or embed an image in code?
2The Solution
Base64 converts binary data into text using only 64 "safe" characters that work everywhere: A-Z, a-z, 0-9, +, /
Simple Example: Converting "Hi!" to Base64
The process: Text → Numbers → Binary → Group into 6-bit chunks → Convert to Base64 characters

Base64 makes files about 1/3 larger, but ensures compatibility
Character Set
Uses A-Z, a-z, 0-9, +, / - safe for all text systems

Supported by every programming language and web browser
