Technical Details
Edge Cases & Tricky Inputs
- •UTF-8 multi-byte characters (emoji, CJK) are encoded correctly — each byte is mapped independently.
- •URL-safe Base64 replaces + with - and / with _ to avoid URL encoding issues.
- •Padding characters (=) can be omitted in some implementations but are included by default here.
Performance & Processing
- •Encoding/decoding runs via the browser's built-in btoa()/atob() for ASCII, with a TextEncoder fallback for UTF-8.
- •Files up to 5 MB can be encoded without issues on modern browsers.
Developer Notes
- •Base64 increases data size by approximately 33% — consider this for bandwidth-sensitive applications.
- •Data URIs using Base64 are supported in all modern browsers for images, fonts, and CSS.
Known Limitations
- •Not encryption — Base64 is trivially reversible and provides zero security.
- •Very large files may cause browser memory pressure during encoding.
