A focused tool for each image task

Vizua organizes its catalog into eight collections: compression, conversion, editing, effects, social-media sizing, GIF workflows, assisted image tasks and specialized utilities. The links above cover every available tool, not just a featured selection.

Each page concentrates on one job and provides localized names, instructions, controls and practical guidance in 16 languages. Start with a collection when you are exploring, or choose the exact tool when you already know the output you need.

How to use the catalog

Choose the task that matches your source and intended output, review the supported input and settings on its page, process a representative file and inspect the result before continuing with a batch or replacing an original.

Browser processing and practical limits

The selected file or entered content is processed in your browser and is not sent to Vizua image-processing servers. The page may still use the network for required code, site features, analytics, error monitoring and, in some tools, models or language data.

Vizua does not require an account or impose a daily product quota. Practical limits still depend on the tool, input format, file size, browser memory and device. Preview the result before downloading or sharing it.
