About Image Cosmos

Image Cosmos builds focused image utilities for people who need a quick result without creating an account or sending a personal file to an upload server.

What makes it different

Each tool runs with browser-native image processing. The selected image stays on the user's device, the result can be previewed before download and temporary download links disappear when the page is closed or reloaded.

How the tools are maintained

The site uses one tested processing library for its JPG, PNG and WebP tools. Automated checks cover image dimensions, output formats, file limits, page metadata, crawlability and the controls required for each task. Platform-size guides link to the primary platform guidance used for their dimensions and show when that guidance was last checked.

What Image Cosmos does not do

Image Cosmos is not cloud storage and does not keep a library of user images. It is also not a full photo editor. The service is deliberately limited to common single-image tasks that can be completed locally and explained clearly.

Accuracy and limitations

Browser format support and final file size can vary by device. Platform requirements also change. The tool pages explain these limits before processing, and the methodology page describes how results and size guidance are produced.
