Tips from how Base64 Encoder & Decoder actually works, and mistakes worth avoiding.
Pro tips
- Keep a working copy of your input before running a destructive operation — undo is a browser back-button, not a history stack.
- When something looks wrong, check the start of the input first — most parsing errors cascade from one early character.
- Bookmark this page. It is a static URL with no login, so it works the same way every time you need it.
Common mistakes
- Assuming a paid tool would give a more "official" result — the underlying parsing logic is the same either way.
- Not checking for trailing commas, smart quotes, or copy-pasted invisible characters — the most common source of a confusing error.
- Working directly on the only copy of an important file instead of a duplicate.
Frequently asked questions
About Base64 Encoder & Decoder and how Tarumak Studio works.
What can I encode with Base64?
Text strings, HTML, JavaScript, CSS and binary files such as images and PDFs. Base64-encoded images can be embedded directly in HTML or CSS.

It encodes binary data as ASCII text, making it safe to include inside JSON, HTML attributes, XML documents and email messages.
Does encoding increase file size?
Yes - Base64 encoding increases size by approximately 33%. It is a trade-off: inline convenience at the cost of larger file size.
