FAQ

What file types are suitable for Base64 conversion?

Images, audio, video, text attachments and many local files are common scenarios, especially useful during API uploads and resource embedding.

Why convert files to Base64?

Because Base64 can encapsulate file content as plain strings, making it easy to put into JSON, configs, Data URLs or test data for transmission.

Is it suitable for API attachment uploads and frontend embedding?

Absolutely. Many APIs directly require Base64 file content, and frontend commonly uses it to generate Data URLs or inline resources.

Can output be pure Base64 or Data URL?

These scenarios are common, making it easy to select the more suitable output format according to API requirements or frontend usage.
