Is Base64 the same as encryption?

No. Base64 is encoding, not encryption. Anyone can decode a Base64 string without any key. Never use it to secure sensitive data — use actual encryption for that purpose.

What is URL-safe Base64?

Standard Base64 uses the characters + and / which have special meaning in URLs. URL-safe Base64 replaces + with - and / with _ so the encoded string can be used safely in URLs and filenames.
