About this tool collection

Image effects change color, texture, focus or style. This collection ranges from grayscale, sepia and vignette to duotone, gradient mapping, noise, background blur, face blur and red-eye correction.

Some effects apply to every pixel, while others detect or isolate a region. A strong result depends on the source resolution and on settings that fit the subject rather than simply using the maximum intensity.

How to choose the right tool

Duplicate or retain the original before experimenting. Apply one main effect at a time, compare subtle and strong versions and inspect faces, text, edges and skin tones at full size before exporting.

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.
