Is pngquant good?

• Lazy Loading, Code Splitting, and Image Optimization for SaaS Applications

  Optimize images at every step: Compress with mozjpeg/ pngquant, resize to actual display dimensions, serve progressive JPEGs, and use CDNs with on-the-fly optimization (Cloudinary, imgix). - Source: dev.to / 3 months ago

• Chromium Has Merged JpegXL

  No I meant lossy. This is the library I use; https://pngquant.org/. - Source: Hacker News / 6 months ago

• Chrome Jpegxl Issue Reopened

  Fair point, though not entirely true: you can run an image through lossy compression and store the result in a PNG, using tools like pngquant [1]. Likely not as efficient for many kinds of images, but totally doable. [1] https://pngquant.org/. - Source: Hacker News / 8 months ago

• Building an Enhanced Squoosh: High-Performance Local Image Compression with libimagequant-wasm

  The cornerstone of our enhancement is libimagequant-wasm, a WebAssembly port of the industry-standard pngquant library. This library uses a sophisticated color quantization algorithm that produces visually superior results compared to simple palette reduction. - Source: dev.to / 9 months ago

• Scripts I wrote that I use all the time

  Nice. I have a command similar to the one listed "removeexif" called prep_for_web which takes any image file (PNG, BMP, JPG, WebP), scrubs EXIF data, checks for transparency and then compresses it to either JPG using MozJPEG or to PNG using PNGQuant.

• Random Code Inspiration Volume 2

  Image-shrinker is a simple, easy to use open source tool for shrinking images. Under the hood it uses pngquant, mozjpg, SVGO, and gifsicle. You can also install these tools individually if you need to compress some images. I often use pngquantafter exporting PNGs for web projects from Figma or similar tools. I literally run it like this:. - Source: dev.to / almost 3 years ago

• keeping collection size down (for ankiweb) when needing lots of image cards/notes

  Searching more I found https://pngquant.org/ which I could add to my bulk workflow to make most png's approach the jpeg size. Source: about 3 years ago

• screen capture/snapshot utility with image optimization support/configurability

  But this did prompt me to do some searching, and I see https://pngquant.org/ which seems to achieve jpeg like size reduction while maintaining the file as a png. One difference they note is that this method will typically preserve sharp edges better than jpeg (which is probably a strong plus for my type of use case). Source: about 3 years ago

• Exported png image with color-to-alpha edit is huge

  Pngquant is also great for shaving filesizes down, but unlike oxipng, it's explicitly lossy. It'll reduce colors and even dither, but it will try to keep an image visually similar. Https://pngquant.org/. Source: over 3 years ago

• So, anyone else wants GIF export?

  Gif's uses a limited palette of 256 colors. How do you make that palette. There are many options just here. A user defined palette, a palette based on the average use of colors (perceptually based on the human eye or just based on raw image data), create it using the pngquant library or maybe some machine learning voodoo? And these are just the one I could think of right now:) Following that, should you be able... Source: over 3 years ago

• What’s the best lossless image format?

  If your dataset allows it, I would look at pngquant for "lossy" compression of PNG images by means of color quantization: https://pngquant.org/ This works absolute wonders if you are talking about images with a limited amount of colors and without many gradients. I use it to compress screenshots of websites, which, if you think about it, are mostly large blobs of uniform colors with hard edges. I also use it every... - Source: Hacker News / about 4 years ago

• Colors distorted after PNG > AVIF Photo conversion

  Except that you don't know that with PNG either, other than for images you've transcoded yourself. Plenty of PNG optimization programs use lossy methods (AFAIK mostly color quantization, see pngquant), and you can't know if an image you got off the internet has been run through such a processor. And besides, you never know what's been done to the image prior to it being converted to PNG, making it non-lossless. Source: about 4 years ago

• 3 idiots fighting while a gigachad teaches a life lesson to his student

  Generally speaking, absolutely. In this case, no. These were core contributors to AV1, JPG XL, and so on. For example, one of them was Kornelski, the guy who wrote https://gif.ski/ and https://pngquant.org/. They know more about this shit than you and me, and between also explained to me how bad a choice APNG was. Source: over 4 years ago

• Best quality .png?

  While full PNG is lossless, you can still do lossy 8-bit PNG with pngquant, using a custom palette - and it is an excellent way to optimize a PNG for size while minimizing quality loss. It is not going to win you any awards for medical photography, but if you are producing graphics for the web, pngquant is awesome. It is kinda-like mozjpeg for PNGs. Source: over 4 years ago
