FAQ

What is Base64?: A binary-to-text encoding that represents data as a string of ASCII characters. Commonly used for embedding images in HTML/CSS, email attachments, and API payloads.
What is the difference between Standard and URL-safe Base64?: URL-safe Base64 replaces + with - and / with _ so the output can be used in URLs and filenames without escaping.
Is my data uploaded anywhere?: No. All encoding and decoding happens locally in your browser.
