Compressed image is bigger than the original about swift-png HOT 8 CLOSED

hi, can you share the smaller image?

from swift-png.

Thanks for replying, I gave up on this idea. The image was just a screenshot I took from my desktop using cmd + shift + 4 nothing special about it. Feel free to close the ticket, otherwise just leave it open as future reference for people trying to reduce file size.

okay, i'm still very interested in how the first image is half the size, so if you have time to attach a copy of it, that would be greatly appreciated :)

Sorry, I already deleted the file I was using for testing.

I can give you this image:

I ran it through pngquant which was the library I was looking to replace with swift-png. The image size is as small as it gets (tinyPNG produces an even smaller file, but they are closed source). I would have liked for swift-png to have produced such a small file size, or at least close to it, even if it required tweaking.

This is the original screenshot taken with cleanShotX

ah, that explains it! pngquant is a lossy image compressor, swift-png is a lossless image codec. lossy algorithms will of course produce smaller output files, but at the expense of information loss and ability to re-encode.

Makes sense 👍 thanks!
