FAQ
Frequently Asked Questions
What is Base64 encoding used for?
It converts binary data (like images) into text so it can be safely sent in emails, embedded in HTML, or stored in text-based systems like JSON or XML.
Can I encode both text and files?
Yes – enter any text to encode, or upload a small file. The output is a Base64 string you can copy and use anywhere.
Can I decode Base64 back to the original?
Yes, our tool works both ways – paste a Base64 string and decode it back to readable text.
Is Base64 the same as encryption?
No – Base64 is encoding, not encryption. Anyone can decode it back. Do not use it to protect sensitive data.
Are my files uploaded to a server?
No – everything is processed right inside your browser. Your data never leaves your device.
