Terms of Use
Plain terms for a free utility site.
Last updated: September 5, 2026
Using the service
The tools are provided free of charge for personal and commercial use. You may use the output — barcodes, QR codes, labels, converted files and calculations — however you like.
You may not use the site to process content you have no right to process, to attempt to break or overload the service, or to run automated traffic against it outside a documented API.
Accuracy
The calculators implement standard, documented formulas and the conversions follow the relevant specifications. Even so, results are provided for information only.
Carrier divisors, VAT rates and marketplace commissions change and vary by contract. Check the numbers against your own agreements before relying on them for pricing, invoicing or shipping decisions.
Availability
The service is offered as-is, with no uptime guarantee. Server-backed tools depend on an upstream rendering service and can be temporarily unavailable.
Subscriptions and billing
Paid plans (Starter, Pro, Advanced) are billed monthly or yearly in advance and renew automatically until you cancel. Prices are shown, and charged, in your local currency and tax where applicable.
Checkout and billing are handled by our reseller, Paddle.com Market Limited, who acts as the Merchant of Record for these purchases. Paddle handles payment collection, sales tax/VAT and refunds for your order — see the Refund Policy for how to request one.
You can cancel a subscription at any time from your account's billing page; cancelling stops the next renewal but does not itself refund the current billing period.
We may change plan prices or features with notice; a change takes effect at your next renewal, not mid-cycle.
Liability
To the extent permitted by law, we are not liable for losses arising from the use of the tools or from reliance on their output. If a result matters commercially, verify it.
Changes
Tools may be added, changed or retired, and these terms may be updated. The date above always reflects the current version.
