How It Works

Choose Encode or Decode mode.

Paste text or drop a file.

Copy the Base64 result or download output.

Unlike cloud converters, zero bytes of your document or image are sent over the network.

No upload queue, no download wait times. Processing is powered by your own CPU & GPU.

No 50MB file size ceiling or hourly usage caps. Handle heavy files right on your hardware.

Does this support UTF-8 special characters?

Yes, standard TextEncoder and TextDecoder APIs are used to handle emoji and multi-byte characters accurately.

Decode JSON Web Tokens (JWT) to inspect header, payload, and expiry dates.

Encode or decode strings to URI-safe percent-encoded format.

Generate customizable placeholder text by paragraphs, sentences, or words.

Deduplicate lists, remove empty lines, and sort alphabetically.
