Frequently Asked Questions
Is Base64 the same as encryption?
No. Base64 is an encoding method, not encryption. It is easily reversible and provides no security for sensitive data.
Can I encode large files?
This tool is optimized for text and small data chunks. For large images, we recommend a dedicated Base64 image converter.
