Frequently Asked Questions

Privacy, transparency, quality, and batch ZIP.

Do my photos get uploaded?

No. This page runs in your browser. Your photo files are not sent to a NixRey server. The page may load normal app/runtime code like any website. That is app/runtime code, not an upload of your image.

How do I convert PNG to WebP?

Drop or paste a PNG. WebP is already selected. Pick High, Medium, or Low, then press Convert. Download under Preview.

Does WebP keep transparency?

Yes. WebP can keep a clear area from the PNG.

Can I convert more than one PNG?

Yes. Add several PNG files and leave the ones you want checked. Press Convert included. Download All ZIP packs those files.

Will the file get smaller?

WebP is often smaller than PNG. The savings depend on the photo and the quality you pick.
