About File to Base64 Encoder
Convert any type of file to Base64 format instantly with our free online encoder. This versatile tool supports documents, images, audio, video, archives, and all other file types, converting them to Base64 encoded strings for use in web development, data transmission, and storage systems. Perfect for developers who need to embed files in HTML, CSS, JSON, XML, or transmit binary data through text-only protocols like email or HTTP.
Our file to Base64 encoder processes files entirely in your browser using client-side JavaScript, ensuring your sensitive data remains completely private and secure. No files are uploaded to any server - your data never leaves your device, making it ideal for confidential documents, personal photos, proprietary code, and sensitive business information. The encoder handles large files efficiently with progress tracking and provides instant Base64 output with copy-to-clipboard functionality.
Simply drag and drop any file or click to select it from your device, and the tool will automatically convert the entire file to a Base64 encoded string. Use the encoded result as data URIs in web applications, embed files in JSON or XML documents, or transfer binary data through text-based systems that only support ASCII characters. Supports unlimited file sizes (limited only by your browser's memory) and preserves the complete binary data of your original file.

Frequently Asked Questions
What file types can I convert?
You can convert any file type to Base64, including documents (PDF, DOC, XLS), images (PNG, JPG, GIF), audio (MP3, WAV), video (MP4, AVI), archives (ZIP, RAR), and any other binary or text file.
Why would I use Base64 encoding?
Base64 encoding is widely used to embed files in web development (data URIs in CSS/HTML), API responses (JSON/XML), email attachments, and data transmission over protocols that only support text. It converts binary data to ASCII text format.
Is there a file size limit?
Since encoding runs in your browser, the limit depends on your device's available memory. Very large files (hundreds of MBs) may cause the browser to slow down or run out of memory. For most files under 50MB, performance is excellent.
Is my data private?
Completely. All file processing happens client-side in your browser using JavaScript. Your files are never sent to any server, ensuring 100% privacy and security.
