FAQ

Questions about Convert to WebP

Clear answers for privacy, formats, batch processing, and output quality.

Are my images uploaded to a server?

Core tools run in your browser. For the MVP flow, Kompresio processes previews, compression, conversion, resizing, metadata cleaning, and ZIP export locally on your device.

Can I process multiple images?

Yes. You can add multiple files to the queue, process them together, and download the results individually or as a ZIP archive.

Does compression reduce quality?

Lossy formats can reduce quality if the quality value is too low. The balanced presets use practical values for smaller files while keeping the image visually clean.
