Frequently Asked Questions
What is Base64?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format, often used to encode data embedded in HTML, CSS, or JSON.
Can I encode images or other binary files?
Yes. Our tool fully supports uploading binary files up to 50MB and converting them into Base64 format.
Are my files uploaded to the server?
Files are sent to our lightweight, rate-limited local Go service, processed in memory, and immediately sent back to you. We never save your files.
