A little less friction.
ERITHRA brings practical online tools together in one thoughtfully designed workspace.
Tools for the work between the work
A smaller image. A clean data file. A document in the right order. ERITHRA is built around these everyday tasks: useful tools with clear controls, straightforward results, and honest explanations.
Simple by design
The platform groups an expanding collection of utilities into ten categories. Most operations run entirely in your browser, so you can work without creating an account or installing a desktop application. Individual tools describe their formats, limits, and any external services.
Built to be useful
ERITHRA favors practical functionality over promises. File-size reductions vary. Reference exchange rates are dated. Browser features differ. The workspace explains these details so you can decide whether a tool fits your task.
Find your next useful tool
Browse a category when you know the kind of task, or search the full collection when you have a specific result in mind. Practical guides explain the details behind common workflows.
