الأسئلة الشائعة
What's URL-safe Base64?
It replaces + with - and / with _ so the string can appear in URLs without percent-encoding. Padding = characters are sometimes stripped too.
Does it handle Unicode?
Yes. Text is UTF-8 encoded before Base64 conversion, so emoji and non-ASCII characters round-trip correctly.
Is my file uploaded?
Never. All encoding and decoding runs in your browser via native APIs. Neither text nor file bytes leave your device.
What's the file size limit?
Bound by your browser's memory. Files under 50 MB typically encode instantly; larger files may pause briefly.
