Base64 Strings Extractor & Decoder

Paste artifact text, a hex dump, or any log and every Base64 blob of 12+ characters is found and decoded in place - with its offset - so the readable strings buried in the dump surface immediately.

Why use Base64 Strings Extractor & Decoder?

Extracts every Base64 blob (12+ chars), standard and URL-safe variants

Shows each hit's offset, decodes it, and flags blobs that are binary, not text

Built for forensic string review - paste output from Cellebrite UFED / Physical Analyzer or any hex dump

100% local: pasted artifacts never leave your browser

How it works

  1. Export or copy text/strings from your artifact (UFED, Physical Analyzer, hexdump, log).
  2. Paste the text into the input box above.
  3. Read each decoded blob; binary-only blobs are labelled instead of dumped.

FAQ

What exactly does this do?

It scans what you paste for Base64-encoded data and decodes every hit. A full UFED extraction database is not parsed - paste the text, string list or hex dump you want to search.

Why are some blobs shown as '(binary, N bytes)'?

Those decode to bytes that aren't readable UTF-8 text (images, packed data, etc.). They are reported as binary instead of printing garbage.

Is my data sent anywhere?

No. Extraction and decoding happen locally in your browser.
