Output and limitations
Encode Unicode text as Base64 or decode Base64 back to text.
Text only, up to 12,000 characters. Decoding requires valid UTF-8. Base64 is an encoding, not encryption.
Where are my files processed?
Selected files are processed in your browser. Importing a URL uses the download service to retrieve the remote file.
What if processing fails?
Check the supported formats and file limits, then try a smaller file. Keep an original copy. A clear error message will explain an unsupported input or an unavailable processing service.
