FAQ

What is Base64 encoding?

Base64 is an encoding scheme that converts binary data into ASCII text, commonly used for transmitting binary data in text protocols such as email attachments, URL parameters, and CSS image embedding.

Does Base64 encoding increase data size?

Yes, Base64 encoding increases data size by approximately 33%. This is because every 3 bytes of binary data is encoded as 4 ASCII characters. Despite the size increase, it ensures safe data transmission in text environments.

What file types are supported?

Supports Base64 encoding for all file types including images (PNG, JPG, GIF, SVG), documents (PDF, DOC), audio, video and more. File size limit is 10MB.

What is URL-safe Base64?

URL-safe Base64 (Base64url) is a variant that replaces '+' with '-', '/' with '_', and removes padding '=' characters, making it safe to use in URL parameters.

Can encoded data be restored?

Absolutely. Base64 is a reversible encoding method, not encryption. Using this tool's decode function can restore 100% of the original data without any loss.
