URL Encoder Decoder: Instantly Encode and Decode URLs Online
Managing URLs often requires encoding special characters or decoding encoded links back to readable format. Our URL Encoder Decoder simplifies this process, allowing users to easily encode or decode any URL or text string in one click.
Whether you’re working on SEO optimization, web development, or data migration, this tool provides precise results instantly. It’s built for both developers and marketers, supporting text input as well as file upload.
You can choose whether to Encode (to make URLs web-safe) or Decode (to convert back to human-readable text). After that, simply click Generate, and your result will appear instantly.
The tool also includes an Upload File option that loads a .txt or .csv file of up to 2 MB into the input box, so you can convert its whole text in one go.
How to Use the URL Encoder Decoder
-
Enter or Paste Your Text or URL:
Copy-paste the URL or code snippet into the input box.
-
Select Mode:
-
Choose Encode to convert characters like spaces and symbols into URL-safe format.
-
Choose Decode to convert encoded strings (like
%20 or %3A) back to readable text.
-
Pick an Encoding style. Percent-encoding (a space becomes
%20) is the default and suits a single value such as a query parameter. Form encoding writes a space as +. Whole URL, available when encoding, keeps : / ? & = # as typed so a full address keeps its structure.
-
Click “Generate”:
Instantly view your encoded or decoded output.
-
(Optional) Upload File:
Upload a .txt or .csv file (up to 2 MB). Its text is loaded into the input box. Then click Generate.
