Base64 Encoder / Decoder

Encode plain text to Base64 format or decode Base64 strings safely inside your browser.

À Propos de Base64 Encoder / Decoder

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. Toolerk allows you to encode and decode Base64 data with full Unicode (UTF-8) support, ensuring accented characters, emojis, and symbols translate properly.

All Base64 encoding and decoding operations take place on your local CPU. Credentials, authorization headers, or sensitive text are never transmitted over the internet.

Foire Aux Questions

Does Base64 encrypt my text?

No, Base64 is an encoding scheme, not encryption. Anyone can decode a Base64 string back to its original form.

Does this tool support emojis and non-ASCII characters?

Yes, our implementation uses UTF-8 byte serialization to handle all Unicode symbols, characters, and emojis cleanly.

Is there a character limit?

Because processing happens on your local device, you can encode and decode very large strings without server size restrictions.
