Veelgestelde Vragen

Wat is Base64 encoding?

Base64 is a binary-to-tekst encoding scheme that represents binary data in ASCII tekenreeks formaat. It is veelvoorkomendly used for transmitting data over media designed for tekst, such as embedding images in HTML or emAIl attachments.

Wanneer moet ik Gebruik Base64?

Use Base64 when u need to embed binary data (images, files) in tekst-based formaats like JSON, HTML, CSS, XML, or emAIl. It is also used for basic data obfuscation and API authentication headers.

Comprimeert Base64 gegevens?

No, Base64 actually increases data size by approximately 33%. It coderens 3 bytes of data into 4 ASCII characters. Use compression before Base64 if file size matters.
