How to Use the PDF to Base64 Converter
This tool allows you to convert PDF files to Base64 strings entirely in your browser. Your files are never uploaded to any server - all processing happens locally on your device.
Step-by-Step Guide:
- Click the "Select PDF" button or drag and drop a PDF file onto the upload area
- Wait a moment while your file is processed (larger files take more time)
- Once converted, your Base64 string will appear in the text area
- Use the "Copy" button to copy the string to your clipboard
- Use the "Download" button to save the Base64 as a text file
- Click "Reset" to clear the current file and start over
Common Use Cases:
- Web Development: Embed PDFs directly in HTML or CSS as data URIs
- API Integration: Send PDF files as Base64 strings in API requests
- Data Storage: Store PDFs as text in databases or JSON files
- Email Attachments: Include PDFs in emails as encoded text
- Document Processing: Prepare files for encryption or encoding workflows
Technical Information:
Base64 encoding converts binary data into a string of ASCII characters. This makes it possible to transmit binary data over text-based protocols. Our converter uses JavaScript's FileReader API to process your PDF files directly in your browser without any server interaction.
