Tool Factory at ateamkit.com is a free collection of browser tools for finance, SEO, developers, file conversion, math and home projects. There is no signup, no account and no upload.

For marketers and site owners, the SEO tools include a UTM builder that can also generate links in bulk from a CSV, a robots.txt builder, a schema markup validator, a domain age checker and a CPM calculator.

Developers get quick utilities they reach for every day: a JSON formatter, a JWT decoder, a SQL formatter, a UUID generator and a cron expression generator.

The convert section handles common file jobs without sending anything to a server: HEIC to PNG and HEIC to PDF, PNG to JPG, CSV to Excel, Excel to PDF and JSON to CSV, plus unit tools like millimeters to inches and a cubic yard calculator.
