Base64 to File Converter

Base64 turns binary data into plain text so it can travel through systems that expect text. It is commonly used for inline images, email attachments, API payloads, and copying small files into code or JSON.

This tool supports both directions. You can encode any uploaded file into a Base64 data URL, or paste Base64 text to recover a downloadable file with the MIME type you choose.

• Useful for quick API testing when a service expects Base64 text instead of an uploaded file.
• Handy for embedding small images or text files into HTML, Markdown, or JSON snippets.
• Good for reconstructing a file from a Base64 payload you received from another tool or endpoint.

Base64 strings are larger than the original file, so they are not ideal for very large assets. If you are decoding data from outside this tool, make sure it is valid Base64 and pick the correct MIME type so the downloaded file opens correctly.
