File to Base64 Converter & Decoder
Convert any file to Base64 encoding or decode Base64 strings back to downloadable files. Support for images, PDFs, documents, and all file types. Secure browser-based conversion with no server uploads - your files never leave your device.
Encode and decode files to/from Base64 format.
Why Convert Files to Base64? Base64 encoding transforms binary files (images, PDFs, videos, etc.) into plain text strings that can be safely embedded in JSON, XML, HTML, or transmitted through text-based protocols. This is particularly useful when working with REST APIs that don't support multipart file uploads, embedding small images directly in CSS/HTML to reduce HTTP requests, or storing file data in databases that primarily handle text.
Common uses: File upload, drag & drop, data URL generation, download support.
Supported File Types: All file types are supported including images (JPG, PNG, GIF, SVG, WebP), documents (PDF, DOC, DOCX, TXT), archives (ZIP, RAR), audio (MP3, WAV), video (MP4, AVI), and more. The tool automatically handles the binary-to-text conversion regardless of file format.
Privacy & Security: Your files are processed entirely in your browser using the HTML5 FileReader API. No files are uploaded to our servers or any third-party services. All encoding and decoding operations happen locally on your device, ensuring complete privacy and security for your sensitive documents and images.
