UTM Decoder

UTM Decoder is a free online tool that extracts, analyzes, and displays UTM tracking parameters from any URL. Paste a tagged link and instantly see each UTM parameter broken down in a clean table — plus get a stripped clean URL ready for sharing.

• Visual tag cards: Color-coded cards for each UTM parameter for quick scanning
• Batch decode: Process multiple URLs at once and compare UTM values side by side
• Export to CSV: Download batch results as a spreadsheet
• Copy clean URL: One-click copy of the stripped URL
• Edit in Builder: Send decoded parameters to the UTM Builder to modify and regenerate
• 100% private: No server processing, runs entirely in your browser

1. Paste a URL: Enter any URL with UTM parameters into the input field.
2. View the breakdown: UTM parameters appear as color-coded cards with the clean URL below.
3. Copy what you need: Copy the clean URL, individual parameter values, or the full breakdown.
4. Batch mode: Switch to Batch, paste multiple URLs, and compare their UTM parameters in a table.
5. Export: Download the batch results as CSV for reporting.

Input URL:

https://example.com/sale?utm_source=google&utm_medium=cpc&utm_campaign=summer%20sale&utm_content=banner_1&ref=abc

Decoded output:

utm_source: google | utm_medium: cpc | utm_campaign: summer sale | utm_content: banner_1

Clean URL: https://example.com/sale?ref=abc

Note how %20 was decoded to a space, and the non-UTM ref=abc parameter was preserved in the clean URL.
