Frequently asked questions

What is Base64?
Base64 encodes binary data into an ASCII string using 64 printable characters. It is widely used to embed binary data, like images or files, in text-based formats such as JSON, HTML, CSS, or email.
What is URL-safe Base64?
Standard Base64 uses + and / which are special in URLs. URL-safe Base64 replaces + with - and / with _, making it safe in URLs and HTTP headers without percent-encoding.
Is my data sent to a server?
No. Encoding and decoding uses the native browser btoa()/atob() functions. Nothing leaves your device.
Can I encode files?
Yes. Switch to the "File → Base64" tab, drop any file, and the tool outputs its full Base64 representation, useful for data URIs and embedding attachments.
