pngquant VS Online PDF Compressor

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 / 8 months ago

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: 12 months ago

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: 12 months ago

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 1 year ago

So I tried several online pdf compression tools, and of these pdfcompressor.com seemed best. It achieved 90%+ compression ratios on the files in question (vastly improving scrolling), allows batch processing (<= 20 files) & doesn't apply daily limits. IDK where its revenue stream comes from, but I hope it stays around! &/ publishes whatever methods are being applied; it's getting far better results than I've been... Source: about 2 years ago
