About this tool collection

Image compression reduces file size so pages load faster, attachments are easier to send and storage lasts longer. The goal is not simply the smallest file, but a useful balance between size and visible quality.

This collection covers JPEG, PNG, WebP, GIF and PDF compression. Each format behaves differently: photos tolerate adjustable lossy compression, transparency often needs PNG or WebP, animation needs GIF-aware processing and documents need a PDF-specific workflow.

How to choose the right tool

Choose the compressor that matches the source format. Start with a moderate quality setting, compare the preview with the original and lower the quality only while the result still looks right for its intended use.

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.
