About

A calmer way to handle everyday files.

MorphoThat is a collection of browser tools for image, document, PDF, data, text, archive, and media files. Choose a local workflow, see what it accepts and creates, and download the result without creating an account.

Our approach

We prefer useful defaults, clear trade-offs, and straightforward limits. Each tool explains what the browser can process, when a format may change in size or quality, and which details are not carried into the result.
