URL Encoder & Decoder

Workflow & Usage

1. Pick your mode: Encode (raw text → percent-encoded) or Decode (percent-encoded → text).
2. Choose scope:

• Component for path segments or query values (safest).
• Full URL for an entire link (keeps URL separators intact).

3. Set options:

• Spaces as “+” (encode only) for form/query compatibility.
• Lowercase %hex to normalize encoding style.
• “+” as space (decode only) to interpret plus signs as spaces.

4. Single or Batch:

• Single: process the whole textarea.
• Batch: one item per line; enable Trim lines to ignore accidental spaces.

5. Paste/type input. Output updates live.
6. Copy the result with one click.

The badges on top show Mode, Input type, Items, Output lines, and Output chars so you can sanity-check results at a glance.

Use Cases

• Web Development & APIs Encode query parameters safely before building URLs, avoiding broken links or injection issues.

• Form Data Debugging Inspect or correct URL-encoded form submissions and query strings directly in the browser.

• Automation & Scripts Prepare encoded payloads for shell commands, curl requests, or API calls without external tools.

• CMS or Spreadsheet Cleanup Decode messy or double-encoded links copied from databases or exported CSVs.

• SEO & Redirect Management Check and normalize URL slugs, redirect targets, and tracking parameters for accuracy.

• Testing & QA Quickly test edge cases with emoji, special characters, or non-Latin text in URLs.

• Batch Transformations Convert entire lists of paths, keywords, or slugs - one per line - for import into CMS or routing systems.

Tips for Best Results

• When in doubt, use Component. It’s safer for values and path parts, especially with & and =.
• Don’t double-encode. If you see %252F, you encoded %2F again. Decode once, then re-encode correctly.
• Only wrap when required. Modern APIs rarely need line-wrapped or prettified URLs; keep them compact.
• Batch transforms for migrations. Paste one path/value per line to clean up old data quickly.

How It Works

All logic runs directly in your browser:

• Two precise modes. Component → encodeURIComponent (for path segments, query values). Full URL → encodeURI (for an entire URL; preserves reserved separators like :/?#[]@!$&'()*+,;=).

• Batch by newline. Process many lines at once. Optional Trim lines keeps your alignments tidy.

• Form quirks, handled. Spaces as “+” converts %20 → + during encode to match application/x-www-form-urlencoded. “+” as space converts + → space before decode (common for query strings).

• Cosmetic normalization. Lowercase %hex toggles %2F → %2f while leaving plain characters untouched.

• Resilient decoding. Tries decodeURIComponent (strict), falls back to decodeURI (lenient); surfaces a clear error if input is broken.

No uploads, no servers, no tracking - just instant URL transforms in memory.
