It sounds like we want to lower the 'installable' icon requirement to the actual Chrome minimum of 144px.įor the 512x512 recommendation, it's worth pointing out that this isn't a manifest audit, it's a splash screen audit, specifically: if you install your PWA using mobile Chrome, will you get a good looking splash screen?įailing this audit does not imply an invalid manifest or PWA (and Lighthouse doesn't (and shouldn't) say this). I think there are three aspects to this issue that we should separate: svg thus saving Users Data and Speeding up the loading of a PWA. I would like to see both Google Chrome and Lighthouse work together to create a solution by allowing Developers to use 512px by 512px icon sizes and better image formats.

Please note I have filed an issue with the Google Chrome team found here: svg which would have the best quality displaying various icon sizes. webp (for even better reduced file size and quality) or a vector such as. jpg (for reduced file size) or the next gen image format.

Though I am not suggesting to not use 512px by 512px icons and maybe in the future we end up having 1024 x 1024 with Mobile devices getting better screen displays as time goes by. This seems to be a complete waste of file size space and will give a negative performance to PWA's and use up people's Data Plans on Mobile networks. You can see the following information recommendation by Lighthouse found here: png files for the icons in the manifest file. Lighthouse suggest to Developers to use 512px by 512px.
