About this tool collection

Image utilities solve specialized tasks that sit outside ordinary editing: reading metadata, sampling colors, generating palettes and icons, comparing images, creating QR or barcodes, building collages and preparing passport photos.

The collection also includes Base64, ICO, contact-sheet, signature, ASCII and screenshot workflows. Each utility exposes only the controls required for its output.

How to choose the right tool

Choose by the output you need and verify the result in its real destination. Scan generated codes, inspect metadata, test icons at small sizes and confirm document or passport requirements with the receiving authority.

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.

Continue your workflow with another Vizua category. Every collection uses localized routes and links directly to its available tools.
