Free seller tools

Five practical tools for merch and print-on-demand work.

Calculate profit and target prices, convert pixels to print dimensions, inspect image resolution, and generate clean product SKUs. Every core tool works without account creation.

Pick the right calculator

Which tool should I use?

The two pricing calculators intentionally answer different questions, while the print tools separate manual dimension math from checking a real image file.

What do I earn at my current selling price?

Use the POD Profit Calculator to subtract product costs, shipping, and percentage fees from a known sale price.

What price do I need for a target margin?

Use the Margin & Break-even Calculator to work backward from fixed costs, fees, and the profit margin you want.

How large can these pixels print at a chosen DPI?

Use the Print Size Calculator when you already know the pixel dimensions and want inches or centimeters.

Is this actual image file large enough for print?

Use the Image Resolution Checker to read a JPG, PNG, or WebP locally in your browser and compare print sizes.

How can I create consistent variant SKUs?

Use the SKU Generator to build readable identifiers across colors, sizes, and other variants in one batch.

How the toolkit is organized

Focused by seller workflow.

Each utility stays narrow enough to explain its assumptions and return a useful answer without a dashboard or setup flow.

Profit & Pricing

Make faster pricing decisions with calculators built around cost, margin, and break-even points.

Print & Design

Check dimensions and print-readiness before a design reaches a production workflow.

Seller Utilities

Small, practical tools for the repetitive operational work behind a merch catalog.
