Hoe om te gebruik Base64 encoder decoder
Base64 encoder decoder converts text to Base64 using the exact UTF-8 bytes, or decodes Base64 back into UTF-8 text. A URL-safe option uses - and _ instead of + and / and omits padding. When decoding, a leading data: URI prefix is removed, and invalid characters, padding or non-UTF-8 bytes are reported as errors.
- Type or paste your source, or load an example.
- Change the basic settings or open Advanced mode to fine-tune the result.
- Review and copy or download your result. Pause Live results to run manually. Sources or individual settings above 20,000 characters require an explicit run.

Gereelde vrae
How do I decode a Base64 string?
Turn on Decode, paste the Base64 text and run the tool. Surrounding spaces and a data: URI prefix are removed first, and the result is shown as UTF-8 text.
What is URL-safe Base64?
URL-safe Base64 replaces + with - and / with _ and leaves out the = padding. Turn on the URL-safe option for both encoding and decoding when working with tokens or URL parameters.
Can I decode Base64 that contains an image or binary file?
No. Decoded bytes must form valid UTF-8 text, so binary data such as images is rejected. This tool also encodes typed text only, not uploaded files.
Where is my input processed?
