A conversion service that does not need your upload.
Processing runs in the browser on your device. That means your image contents are not sent to MorphoThat just to make a new file. Some formats and very large images depend on the capabilities and available memory of your browser.
Prepare a copy for social media.
Start with a destination-shaped image, then review the result before you upload it yourself. Platform rules and acceptance can change, so these workflows are practical starting points rather than guarantees.
