What you'll find on this site
A set of converters and engineering calculators that run on your own device, with nothing uploaded.
Everything on this site runs in your browser. Files are read and written on your own device using the browser's file and canvas APIs, and none of them are sent to a server.
The tools
An image converter for JPEG, PNG and WebP; an image-to-PDF builder; an engineering unit converter; a tank and vessel calculator; and a plate calculator for the steel a rolled vessel consumes.
What that design buys you
No upload queue, no file size cap beyond your device's available memory, and nothing for us to store or lose. Once a page has loaded, the conversion itself needs no connection.
What it costs
Speed depends on your hardware rather than ours, so a large batch on an older phone will take longer than it would on a server. Processing fewer files at once is the usual fix when a conversion stalls.
