Work with files in your browser

This first version contains two focused workflows: structural metadata cleanup for PNG, JPEG and WebP images, and strict JSON validation, formatting and minification. Processing runs in a separate private workspace. Files and results are not sent to a conversion server.

Choose a workflow

Read the image metadata guide or read the strict JSON guide.

Before you begin

Keep the original file and inspect downloaded results before sharing them. These workflows have explicit size and feature limits. They do not establish that a file is anonymous, legally safe to share, or suitable for every receiving application.

The broader WebUT product remains in construction. These two workflows do not represent completion of its promised tools, countries or languages. This version uses English with GB presentation; it does not infer your residence or legal jurisdiction.
