Free Shopify Tools: Generators & Calculators

Products & catalog

Make UPC, EAN and Code 128 barcodes with correct check digits, and print label sheets from a list or a Shopify product CSV.

Build a SKU for every variant from your own pattern, then import them by CSV or fill the blanks in a Shopify product export.

Build a size chart in centimetres, inches or both, then copy accessible HTML for Shopify or download a PNG or CSV.

Work out profit, net margin and markup per order after fees, shipping, ads and refunds, or the price you need for a target margin.

Estimate Shopify’s subscription, card processing and third-party transaction fees, and see which plan costs least at your sales.

Work out ROAS, break-even ROAS and target ROAS from your margin, plus max cost per acquisition and per click.

Create up to 10,000 unique, hard-to-guess discount codes with your own prefix, then copy them or download a .txt or .csv file.

Resize, pad or crop images to the sizes Shopify and its themes work with, and save them as JPEG, WebP or PNG, in your browser.

Find which theme a Shopify store uses: its name as installed, the original theme and version, and its Theme Store listing.

See which apps a Shopify store loads on its storefront, grouped by category, with the code that revealed each one.
