URL Query String Editor

URL Query String Editor

Query strings are powerful — and annoying to edit by hand.

This tool lets you edit URL parameters visually without breaking encoding:

• Add / remove parameters safely
• Edit values without worrying about escaping
• Reorder parameters (useful for debugging + consistent URLs)
• Copy the full rebuilt URL or just the ?query part

Everything updates live, right in your browser.

What you can do

• Paste any input style
  • Full URL: https://site.com/page?utm_source=google
  • Relative URL: /page?x=1
  • Query-only: ?a=1&b=2 or a=1&b=2
• Edit parameters as a table
  • One row per key/value
  • Duplicate keys supported
• Reorder, duplicate, and remove rows
• Copy outputs
  • Full URL output
  • Query-only output (?a=1&b=2)

Workflow & Usage

1. Paste a URL (or query string) into the input box.
2. The tool parses parameters into the Query parameters table.
3. Edit keys and values:
   • Change utm_source, add utm_campaign, delete fbclid, etc.
4. Reorder parameters if you want stable, predictable URLs.
5. Use the output panel to Copy URL or Copy ?query.

Tip: If you’re building UTMs, keep the output panel visible and tweak values until the URL is exactly what you want.

Common examples

Build UTMs for marketing links

Input:

https://example.com/pricing

Add rows:

• utm_source = newsletter
• utm_medium = email
• utm_campaign = jan_launch

Output becomes:

https://example.com/pricing?utm_source=newsletter&utm_medium=email&utm_campaign=jan_launch

Remove tracking parameters

Delete common tracking keys like:

• fbclid
• gclid
• utm_*
• ref

This is useful when you want a clean canonical URL for sharing or documentation.

Keep duplicate keys

Some systems use duplicate keys:

/search?tag=shoes&tag=sale&tag=summer

This tool preserves duplicates as separate rows so you can reorder or delete them individually.

Options explained

Spaces as “+”

Replaces encoded spaces (%20) with + (often used in query strings and form encoding).

Lowercase %hex

Normalizes percent-encoding to lowercase (for example, %2F becomes %2f) for consistency.

Sort by key

Alphabetically sorts parameters by key, which can help keep URLs stable across edits and reduce diff noise in configs.

Use cases

Marketing & analytics (UTM building)

Create consistent tracked links for:

• newsletters
• paid ads
• influencer campaigns
• social posts

Debugging APIs and web apps

Quickly modify:

• page, limit, cursor
• feature flags like debug=true
• toggles like mode=compact

SEO housekeeping

• remove unnecessary trackers before sharing links
• generate clean URLs for docs
• keep consistent parameter ordering when testing canonical behavior

Tips for clean URLs

• Avoid leaving empty keys/values unless your system requires them.
• Prefer consistent parameter order (Sort by key) when you’re generating URLs programmatically.
• If you’re sharing publicly, consider stripping tracking params to reduce noise.
