TinyJPG VS OptiPNG

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: 7 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.

Compress image using commandline tool (convert / jpegoptim) or online tool - https://tinyjpg.com/. - Source: dev.to / over 1 year ago

Did you compare to PNG crush and optipng? Those are what I used to use because they're easily installable Linux/brew packages. Source: about 1 year ago

Assuming your frames are PNG files, you could use a lossless optimizer like optipng to try if their size can be reduced. I prefer oxipng, which is faster and multithreaded, and seems to have more active development. Source: over 2 years ago
