Frequently Asked Questions

Find Quick Answers

What is a blob and why would I need to convert it?

A blob (Binary Large Object) is a data type that stores binary data like images, audio, or any file content. Converting blobs between formats is useful for data encoding, transmission, or processing in different systems.

What formats can I convert blobs to?

You can convert blobs to Base64 (text encoding), Hexadecimal (hex string), ArrayBuffer (binary buffer), or download as a file with the original MIME type.

Is my data secure when using this tool?

Yes, all conversions happen entirely in your browser using JavaScript. No data is sent to any server unless you choose to use the optional server-side processing for large files.

What file types are supported?

The tool supports any binary file type including images (PNG, JPEG), documents (PDF, DOCX), audio (MP3, WAV), video (MP4), and any other binary data.

Is there a file size limit?

For client-side conversion, the limit depends on your browser's memory. For very large files (over 100MB), use the server-side processing option which handles files up to 500MB.
