URL Encoder / Decoder Online

New

Encode special characters in a URL or query parameter using percent-encoding, or decode an encoded string back to readable text. Choose between a single component or a whole URL.

The interactive URL Encoder / Decoder workspace loads in your browser. Read the practical guide and processing details below.

How to Use URL Encoder / Decoder

Follow these steps, then review your result before using or sharing it.

1

Pick encode or decode

Choose what you want to do.

2

When to use URL Encoder / Decoder

Percent-encode characters that are unsafe in a URL, or decode an encoded address into readable text.

Developer utilities help inspect and transform data during development. Always distinguish readable output from validated or trusted output: formatting JSON does not validate a business schema, decoding a token does not verify a signature, and a generated snippet still needs to be tested in the receiving application.

Get a more useful result

Use component mode for one query value and whole-URL mode for a complete address so separators stay intact.

Use URL Encoder / Decoder on ToolBexa as one step in your workflow, then inspect the exported result before uploading or sharing it. If a receiving website gives a format, dimension or input rule, use that requirement rather than a convenient default.

Limits and common mistakes

Encoding does not make a link safe or working. Double-encoding is a common mistake, so decode first if a value already contains % sequences.

How your input is processed

The core operation runs in your browser. Downloaded results remain on your device, and page preferences may be saved in browser storage. Check the Privacy Policy for server logs, external resources and other site features.

Frequently Asked Questions

When should I use whole-URL mode?

When encoding a complete address, so its structure characters stay readable. For one query value, use component mode.

Is anything sent to a server?

No. It runs locally.
