What Metyris is

Metyris is a collection of focused browser utilities for documents, images, text, calculations and developer tasks. Each page is built around one job, with working controls near the top and enough explanation to understand the result. Tools are free and require no account.

Why browser-based processing matters

File and text tools work inside your browser instead of sending selected content to a processing server. That removes upload queues, avoids server-side file storage and often makes small tasks feel immediate. Results exist in the current tab until you download them or close the page. Calculators and developer transformations also run locally.

How tools are selected

Metyris adds utilities that solve a distinct, common task and can work responsibly in a modern browser. A new page must provide a real functional difference; small keyword or number changes are not enough. Shared engines power related experiences such as image compression targets, which keeps behavior consistent without creating thin duplicate tools.

Privacy and practical limits

No analytics, advertising or account system is enabled. Future measurement is limited by design to generic tool identifiers and cannot include filenames, file contents or entered text. Browser memory still matters: very large PDFs and images may exceed a phone or older computer’s available resources, so every file tool states its working limits.
