For the details that make a difference.

Our purpose

A print project often gets stuck on a small question: will this picture be sharp enough, what will the frame cut off, or how many labels fit on a sheet? Swetter brings those calculations into focused, approachable tools with explanations you can check.

The site serves people preparing photos, cards, labels and small business materials. You can use the tools without an account. Your chosen images are processed in your browser, and exported files are created on your device.

How the tools are checked

The calculations use explicit dimensions and unit conversions. The source includes automated checks for print density, cropping, page scaling, invalid inputs and label geometry. Our guides show worked numerical examples so you can inspect the reasoning as well as the answer.

A calculation is not a physical print test. The tools do not measure printer calibration, image sharpness, color accuracy or paper behavior. For an important job, check your print provider's specifications and make a proof.

How we approach content

Guides are written for the tasks the tools support. We distinguish numerical examples from real print results, link to relevant technical references, and avoid claims of guaranteed print quality. Each guide includes an update date. If you find an error, send the measurements and the page URL so we can investigate.
