About Omnia Toolbox
Omnia Toolbox is a growing collection of small, free tools for everyday jobs, starting with tools for online resellers and people who ship packages from home.
How the tools work
Every tool runs entirely in your web browser. Your files, photos and shipping labels are processed on your own device and are never uploaded to our servers. That keeps them private, and it means the tools work fast with no waiting in a queue.
Why it's free
There are no accounts, subscriptions, credits or watermarks. The site is supported by the ads you see on the pages. We try to keep them out of the way of the tools themselves.
Accuracy
Calculators use published standard rates and fees, which platforms and carriers change from time to time. Results are estimates; always check the platform or carrier for the final figure.
Independence
Omnia Toolbox is independent. It is not affiliated with or endorsed by Vinted, eBay, Poshmark, Depop, Etsy, Mercari, USPS, UPS, FedEx or any other company mentioned on this site. All trademarks belong to their owners.
