URL Encode and Decode - Online
Encode to URL-encoded format or decode from it with various advanced options. Our site has an easy to use online tool to convert your data.
Categories:
URLencoder.org is a free online tool that allows users to encode and decode data into URL-encoded (percent-encoded) format, supporting both text input and file uploads up to 100MB.
🚀 Overview
URLencoder.org provides a simple, web-based utility for percent-encoding and decoding strings or files, eliminating the need for local software installations.
It solves the problem of preparing data for use in URLs, query parameters, APIs, or web forms where special characters must be safely encoded according to URI standards. This is essential for avoiding errors in web development, testing, or data transmission.
Built for developers, web designers, testers, and anyone handling URI data, it offers quick access without sign-ups or downloads.
The tool was created by a small team of developers and engineers as part of a collection of online developer utilities to make coding and data tasks simpler and faster.
✨ Key Features
- Text-based encoding/decoding with real-time preview and copy-to-clipboard functionality (why it matters: instant usability for quick tasks)
- File upload support for encoding binaries like images or documents (up to 100MB; why: handles large or non-text data)
- Advanced options including character set selection (UTF-8 default), newline handling (Unix/Windows), encode each line separately, and MIME-compliant line splitting (max 76 chars/line)
- Live mode using client-side JavaScript for instant, no-upload encoding (UTF-8 only; why: privacy and speed for simple strings)
- Secure HTTPS transmission; files auto-deleted after download or 15min inactivity
🛠 Tech Stack
- Frontend: HTML, CSS, JavaScript (for live encoding)
- Backend: Server-side processing (language unspecified; handles file uploads and advanced options)
- Database: None mentioned
- Auth: None required
- Hosting: HTTPS/SSL-enabled web server (provider unknown)
