About 2BASE64.ORG
2BASE64.ORG is a professional, high-performance web utility designed to convert files and documents into Base64 format directly inside your browser. By utilizing local HTML5 Web Workers, all binary-to-text conversion is executed client-side on your computer. This means your private files never leave your system during local conversion, guaranteeing maximum privacy and speed.
Why Convert Files to Base64?
Base64 encoding is widely used to represent binary data in an ASCII string format. This is extremely useful for embedding images directly inside HTML or CSS files, transferring data via JSON or XML web APIs without encoding issues, and sending file attachments in emails using MIME protocols.
Key Features:
High Performance: Convert files up to 200MB smoothly using asynchronous Web Workers that prevent browser freezing.
Secure & Private: 100% client-side conversion ensures that sensitive data is processed entirely in your web browser.
Dual Download Methods: Download text representations locally or request a server-assisted stream for validation.
All Formats Supported: Easily convert images (PNG, JPEG, SVG, WebP), PDFs, audio files, videos, archives, and spreadsheets.
Privacy Policy
Last updated: June 6, 2026
At 2BASE64.ORG, accessible from https://2base64.org, one of our main priorities is the privacy of our visitors. This Privacy Policy document contains types of information that is collected and recorded by 2BASE64.ORG and how we use it.
1. Client-Side Data Processing
Our core utility operates client-side inside your web browser using HTML5 Web Workers. When converting files directly to Base64 on your device, the file contents never leave your local system. Your files are processed in-browser, ensuring maximum privacy and security.
2. Server-Side Temporary Storage
If you choose to use the "Upload to Server" feature, the file is sent temporarily to our secure server to allow server-side processing or alternative download options. Files are stored in non-indexed, private folders and are completely deleted automatically after one (1) hour of upload time (TTL = 3600s).
3. Log Files
2BASE64.ORG follows a standard procedure of using log files. These files log visitors when they visit websites. All hosting companies do this and a part of hosting services' analytics. The information collected by log files includes internet protocol (IP) addresses, browser type, Internet Service Provider (ISP), date and time stamp, referring/exit pages, and possibly the number of clicks. These are not linked to any information that is personally identifiable. The purpose of the information is for analyzing trends, administering the site, tracking users' movement on the website, and gathering demographic information.
