PNG to WebP FAQ
- Does PNG to WebP upload my file?
- No. Conversion runs in your browser with WebAssembly and the canvas. imissfiles servers never receive the document. Closing the tab discards the working copy.

- How do I convert png to webp without an account?

- Image and page conversions keep the pixels you dropped. PDF compression redraws pages as JPEGs so size drops — pick a higher quality if you need sharper type.
