TinyJPG VS ImageAlpha

Improve your website speed and mobile responsiveness. Google loves websites that load fast. Make sure your pictures aren't heavy. Use apps like TinyJPG. Use the right amount of animation because too much of anything is bad. Source: 8 months ago

Extract the scanned image and resize to make it a bit smaller, then compress the images on tinyjpg.com, merge them all into one pdf file using smallpdf, finally compress the pdf file again on the same website. Source: about 1 year ago

I'd say that a proper OR recommended approach towards optimizing images for the web is to manually compress them with compression tools like TinyJPG or Squoosh before uploading them to your favorite image CDN. Why? you'd ask me. - Source: dev.to / about 1 year ago

Oh and for the file size: compressing is usually better than resizing. And your image is a PNG which is much bigger in size than a JPG and you barely notice the difference. You can use https://tinyjpg.com/ or any proper image editor for good compression or even in Wonderdraft, you can (for sharing on Reddit) better export it as a JPG and at 80% or so.

If anyone wants a internet-free app on OSX, try ImageAlpha! It's great, lots of settings to try and optimize PNGs. https://pngmini.com/. - Source: Hacker News / almost 2 years ago

For non photographic images, I use a combination of ImageAlpha and ImageOptim and sometimes crop the image to 2x of the maximum expected display size (2x so that the image will stay sharp on high-DPI screen). Keep in mind that my method uses the lossy compression approach. Meaning that you wouldn't want to use my method on your master images. Source: almost 3 years ago

Try ImageAlpha by the same author as ImageOptim for transparent PNG optimization. Source: about 3 years ago
