About the Handiwork Base64 Encoder
The Base64 Encoder converts text and files to and from Base64. Encode data into a safe ASCII string for embedding in URLs, JSON, or data URIs, or decode Base64 back to readable text — handled locally in your browser with full UTF-8 support.
How to use the Handiwork Base64 Encoder
- Choose encode or decode.
- Paste your text (or upload a file) into the input.
- Copy the Base64 or decoded result.
What is Base64 encoding?
Base64 represents binary data using 64 printable ASCII characters. It is not encryption — it simply makes arbitrary data safe to transmit through channels that only reliably handle text, such as email bodies, JSON payloads, and data URIs embedded in HTML or CSS.
When to use Base64
Common uses include embedding small images directly in HTML/CSS as data URIs, encoding credentials for HTTP Basic Auth, and storing binary blobs in text-only fields. Note that Base64 increases size by roughly 33%, so it suits small payloads rather than large files.
Frequently asked questions
Is Base64 a form of encryption?
No. Base64 is reversible encoding, not encryption. Anyone can decode it, so never use it to protect secrets.
Does Base64 support Unicode text?
Yes. This tool handles UTF-8, so emoji and non-Latin characters encode and decode correctly.
