Multiple problems with quality param about react-image-file-resizer HOT 2 OPEN

Part of the explanation is for PNG. According to the documentation on toDataURL, the second parameter is ignored for lossless encoding, such as when creating PNG. There appears to be no way to control the compression rate.

It only applies to lossy formats like JPEG and WebP. Which also means that lossless WebP will become lossy after resaving them to WebP.

The reason JPEG becomes bigger, might be in their very nature: re-encoding JPEG means the existing JPEG artefacts are now part of the "original" pixels that needs to go through encoding, which effectively means you'll be getting double JPEG artefacts. Re-encoding a JPEG as another JPEG is never a great idea, unless you're significantly reducing its dimensions.

I suppose resizing images through the browser is just as limited as it is. The only way around this, is to go full serverside. Or I suppose include a full custom library like Sharp on the clientside, which I would not recommend for regular websites, only for locally installed webapps (such as React Native, or Electron).
