FAQ
How do I convert in bulk?
Paste your text into the input box one item per line, then click Bulk Encode or Bulk Decode. The output shows each source line mapped to its result.
Does one failing line affect the others?
No. Each line is converted independently; failed lines show a clear error message in place while all other lines output normally, making problem lines easy to locate.
What content is supported?
Any UTF-8 text including Chinese and emoji. Encode mode converts each line to Base64; decode mode tolerates URL-Safe variants and missing padding.
