Efficient-Compression-Tool VS ImageOptim

Would be interesting to see how all those jpegs fared if run though ECT (https://github.com/fhanau/Efficient-Compression-Tool). I’ve found it can save a surprising amount of space sometimes.

Ah, I misunderstood you there, yes you can build it from source but there are also Windows binaries available on https://github.com/fhanau/Efficient-Compression-Tool/releases/

Did you think about adding support for newer image formats? Video shouldn't be a problem because you already support .mkv and AV1 works within it. How would implementation work? Does ES-DE use libraries from the OS and makes this support easier for that? My biggest gripe are those big .png files. I optimized them with ect but it won't be as good as newer formats can be.

If png size is a concert of yours: Efficient Compression Tool

There are a myriad of PNG (and in general DEFLATE) optimizers and pingo hosts its own benchmark [1]. I believe ECT [2] is the only tool comparable to pingo in terms of compression ratio and speed. But pingo still lacks a license statement and it's even unclear whether you can use this for any purpose at all, probably because it is still "experimental", so if you don't like that you can try ECT instead.

> One thing I didn't check is that you might pay that in decoding time, I've never seen anybody talking about that though.

PNG and in general DEFLATE-based formats are mostly free from this concern because they are comparably simple. The maximum "overhead" you can intentionally trigger is a very large LZ77 window and a very deep Huffman tree; the former is however capped to 32 KB in DEFLATE, and the latter will mostly result in an inferior compression (a long prefix code means a larger file).

I personally prefer ECT, since that gave me the best results when I tested it several years ago.

ECT is the new stuff that is much faster and more efficient than zofpli

Efficient Compression Tool Basically the best FOSS for lossless compression for .png and .jpeg, although not the quickest.

I get the same issue. However, it seems that using ECT on the images fixes the issue: https://github.com/fhanau/Efficient-Compression-Tool

Compressing images: This technique reduces image size without compromising quality. You can achieve this using various image compression tools like TinyPNG or ImageOptim. These tools are specifically designed to manage multiple image formats and compression methods. They help reduce image files, resulting in less data transfer from the server to the user's device. It is advisable to compress images before uploading them to the web server.

ImageOptim: ImageOptim is a free and open-source tool that can be used to compress JPEG, PNG, and GIF images.

ImageOptim - file resizing and optimising images, even on the command line (free)

ImageOptim - Price: Free Image optimizer for Mac that allows you to reduce the file size of your images without losing quality, and strip the metadata.

If you're on a Mac, use ImageOptim to optimize your images: https://imageoptim.com/mac If you're on Windows, I imagine there's a similar app

Bonus points: before you re-import them drop the exports folder into imageoptimfor the most efficient lossless compression imaginable.

ImageOptim — shrink those file sizes!
