01
Turn an opaque value back into readable data
Paste Base64 from a log, API response, or clipboard and see the decoded JSON immediately, without uploading the value to a web converter.
Encode / DecodeDeveloper & Data
Read or prepare encoded text without handing it to a website.
Encode / Decode keeps Base64, Hex, URL encoding, HTML entities, and backslash escaping in one local workspace. Paste a value from a request, response, log, or clipboard, switch direction, inspect the live result, and run it back through the opposite direction when you need to verify the round trip.

What it does
Encode, decode, and verify the text formats that appear in everyday technical work.
Encode or decode Base64, Hex, URL encoding, HTML entities, and escaped text.
See the transformed result live while the original input stays available.
Detect text that already looks encoded and switch to decoding quickly.
Use the output as the next input for a fast round-trip check.
Keep tokens, payloads, and internal values on your Mac.
From opaque to readable
Keep the original, format, and result in one reversible local loop.
A real Base64 payload and a percent-encoded URL prove decoding, automatic format detection, encoding, copying, and the path back through the opposite direction.
02
Recognize encoded text before choosing a direction
Foldout identifies text that looks like Base64, Hex, URL encoding, HTML entities, or backslash escaping and offers the matching decode path without hiding the source.
03
Turn a complete link into percent-encoded text
Encode spaces, separators, and query values into one copyable string, then use the same workspace to decode it again when you need to inspect the original.
Why it belongs
Why Encode / Decode earns a place in the toolbox.
The practical details that make this job faster, clearer, or safer than doing it by hand.
Five formats, both directions
Use the same workflow for Base64, Hex, percent encoding, HTML entities, and backslash escaping instead of opening a different converter for each format.
The source and result stay connected
The input remains visible above a selectable output, making it easy to verify what changed and copy only the value you need.
Round trips take one click
Promote the current result back to the input and automatically reverse direction when an integration needs an encode-decode sanity check.
How to use it
