Optimage

3.2.1

Image optimization using advanced algorithms.

Overview

Optimage is an advanced image-optimization tool to minimize images in a visually lossless way for websites, apps, storage, and sharing. It uses advanced metrics to automatically adjust image quality for up to 10x smaller image files that are visually perceived as originals. Maximum compression ratio is achieved by exhaustively trying various compression parameters and image-data structures, using novel and traditional heuristics. Simple native GUI and universal CLI clients are built to work efficiently across many different platforms on desktops and servers.

Features
  • Lossy (visually lossless) and lossless optimizations
  • Referenceless image-quality assessment
  • Negligible degradation on subsequent runs
  • Nearly optimal compression
  • Fast parallel processing on modern multi-core CPUs
  • Advanced-quality metrics based on human perception
  • Full color management with ICC v4 profile support
  • Smart Convert-to-sRGB option
  • Integration with system file managers
  • Extremely simple optimization settings
  • Strips excessive metadata (Exif, XMP, IPTC, comments, etc.)
  • Losslessly auto-rotates JPEG photographs according to Exif Orientation tag
  • Preserves useful metadata (Android 9-patches, aPNG, etc.)
  • Handles most popular image formats: JPEG and PNG, GIF, and SVG
  • Cross-platform CLI and GUI
  • Minifies Windows icons/favicons (ICO) and Apple icons (ICNS)

Supported file types:

  • JPEG
  • PNG
  • GIF
  • SVG
  • ICNS
  • ICO

What's new in Optimage

Version 3.2.1:
  • Skip broken PDF files
  • Fixed disappearing text in PDF files with missing CID fonts
  • Fixed wrong color conversion in some PDF files created for print
  • Try harder not to become the default app for supported file types

hm, there is the long established free and open source imageoptim.app... but ofc we wont draw any conclusions here .)

I don't know about the former versions but this one excels in optimizing the size of jpegs... to zero! :-o I've just tried it with one jpeg of mine (exported from Photoshop or Graphic Converter, so nothing strange) and it says "100%" optimization with the resulting file being O byte... :-( Even supposing this is a temporary bug, I think it's not a good idea to replace the original without offering the choice in the prefs to keep it intact and save a modified copy near to it.

Hopefully just a temporary bug. I've processed a few thousand images without running into this issue myself.

There's certainly a setting in the prefs to not overwrite the original, and every time you run an optimization that would overwrite the original, you get a warning making sure that's what you want (although there's a checkbox to prevent that warning in the future). Screenshot: https://d.pr/i/9PlDSi

I've just tried it once again and It looks like amongst all the jpegs I have I've managed to pick the only one that gives that issue! :-o
I still can't figure out why and what makes it different, but I must admit that a bunch of other files I've tried just now are processed correctly...
I still think it would be nice to have a pref or a choice in the menu to switch from "overwrite" to "duplicate & optimize" instead of having no choice.

I've tested a LOT of image optimization tools on my large collection of comics totaling 550 GB (412k pages). Most optimization tools are just wrappers around open-source libraries such as PNGCrush, PNGOUT, AdvPNG, etc. ImageOptim is one such tool, and it's very useful. What Optimage brings to the party is a proprietary PNG compression algorithm which consistently gives me 10-20% more compression (losslessly) compared to the suite of open-source tools I already use. That's a very impressive feat. While 10% might not seem like much, that's roughly 55GB in my current comic collection. Optimage does have some bugs in the UI, but the developer has been very responsive and rolled out 3 new releases within a couple weeks with my feedback.

Just wanted to follow up with some concrete numbers from losslessly optimizing "Battle Angel Alita Mars Chronicle Vol 1", which contains 212 PNGs with a mix of color, grayscale, and black&white:

Original Size: 592MB
ImageOptim: 512MB (13% smaller)
Optimage: 447MB (24% smaller!)

I made sure to compare the images using Kaleidoscope to make sure they are indeed identical.

The original and long-time favorite ImageOptim app (available for free) is used by many pro photographers and web designers. This appears to be somewhat of a knock-off with a similar title.
