Optimage VS Oxipng

I use the one https://optimage.app/. Source: 11 months ago

Optimage is a batch image compression/resize app that I use to standardise images sent to me by clients for their website. Source: over 1 year ago

I’ve found Optimage to work better, at least for me. Source: over 1 year ago

I have something like this myself setup to automatically optimize new screenshots using Optimage ($15), but I should be able to walk you through the steps, as everything you need is built into Mac. Source: almost 2 years ago

I personally swear by Optimage. Although its primary function is images, it also does video. It is fast and it has a very generous free offering (24 files per day). It doesn't have many options, but to me, that's a feature, not a bug. Source: almost 3 years ago

I have had good experiences with https://github.com/shssoichiro/oxipng . Although, I suspect this wouldn't give you nearly enough space savings as jpg. Source: about 1 year ago

If you do want the file as a PNG (for transparency and a common format that's well supported), but don't want it so huge, consider something like oxipng. https://github.com/shssoichiro/oxipng. Source: over 1 year ago

Oxipng, pngquant and svgcleaner — optimizing images. Source: over 1 year ago

I wonder how `pngcrush` compares to `oxipng` (https://github.com/shssoichiro/oxipng). Personally, I use `oxipng` if I want lossless compression. However, most of the time, I use `pngquant` instead, since it gives significant size reduction even at `99%` (I can't even distinguish between the original and reduced image).

    pngquant --quality=99 --ext=.png --force file.png

Depending on your workflow it might make sense to export PNGs directly from Affinity and then reduce their size with a utility like Oxipng, which uses all your cores to find the best algorithm for each particular image. Source: almost 2 years ago
