UTM Builder: UTM links in seconds, in your team's standard

When everyone builds UTMs their own way, GA4 sees “Facebook”, “facebook” and “FB” as three different sources, non-standard mediums fall into “Unassigned” and nobody can say for sure which campaign brought in each sale. Building links one by one by hand is also slow and error-prone.

We built a builder that runs entirely in the browser and outputs links that already follow the standard: shortcuts that fill in source, medium and each platform's macros, automatic value standardization and real-time warnings before the link goes into an ad.

• Shortcuts for Meta, Google, TikTok and LinkedIn Ads with each platform's dynamic macros ({{campaign.name}}, {keyword}), plus email, WhatsApp and organic social.
• Automatic standardization: strips accents and surrounding spaces, swaps spaces for _ or - and optionally forces lowercase, without touching the macros.
• Real-time validation: required fields, invalid URL, uppercase, special characters, duplicate UTMs in the link and a preview of the GA4 channel the visit will land in.
• Bulk links pasted straight from a spreadsheet, with CSV export.
• A QR code for each link and a copy of just the part after the ?, for Meta's URL Parameters field.
• History saved in the browser itself, with editing and CSV export, plus editing any existing link by pasting the URL with its UTMs.

• UTM links in seconds, always in the same standard, so GA4 groups each channel and campaign without duplicates.
• Nothing leaves the browser: a static site with no server and no infrastructure costs.
• A free tool with no sign-up.
