Google Page Speed-Like Image Optimization

Question

My website has about 20 thousand product images. Google Page Speed tells me they can be optimized, and it's correct - the difference is huge. Google is able to maintain identical quality and reduce the image size by 70-90%, and Page Speed even optimizes them for me and provides me with a link to the optimized image. This would be great if I only had a few images, but I can't manually update 20k images. I don't want to make any programmatic changes to handle optimization, I'd rather just run all of my images through a piece of software that can optimize them and replace the existing images. I would greatly appreciate it if someone who has been through this before can recommend a good program that can accomplish a job of this size while still maintaining quality. Thanks.

What kind of images? (ie: png, jpeg, ??) – NotMe Feb 16 '12 at 02:58 — NotMe, Feb 16 '12 at 02:58
these particular images are jpeg – StronglyTyped Feb 16 '12 at 02:59 — StronglyTyped, Feb 16 '12 at 02:59

If you're using a Mac I'd recommend http://imageoptim.com since you just drag and drop the files. It saves the files in its original location. For Windows on Adobe AIR some people seem to like Shrink O'Matic - http://toki-woki.net/p/Shrink-O-Matic/

Shrink-O-Matic does not optimize images (sometimes the saved image is even bigger) and seems to destroy animated GIFs (eg. loaders, only the first frame is saved). – Ronald Feb 20 '14 at 13:20
https://imageoptim.com works for me. Thanks Marcus. – Jonas T Dec 22 '16 at 00:20
I've tried using image optim and google still says it can be reduced by over 70% – Oliwol May 21 '17 at 08:43
@Oliwol, perhaps the images are not the right size, meaning the size they're displayed on the page? – Marcus Österberg May 28 '17 at 18:50

You can use this executable within a batch or automatically run it on all images in your IDE/build environment. It's also possible to add it to the Windows Explorer context-menu: http://www.integraxor.com/blog/using-pagespeedpngout-to-compress-jpgpng-with-mouse-clicks/. – Ronald Feb 20 '14 at 13:25

I ended up using a service from Yahoo, SmushIt: http://www.smushit.com/ysmush.it/. It can handle several hundred images at a time. I tried uploading 2,500 and it froze, but had no problem doing 400-500. The compression isn't quite as good as Google's, as Google Page Speed still says it can compress some of them an additional 3-8%, however, I've noticed that Google will sometimes reduce image quality, whereas SmushIt maintained exact quality 100% of the time.

Smush.it doesn't allow images of size more than 1MB – rahul286 Sep 10 '13 at 11:05

Also note that Smush.it changed in a way that you can't select multiple images at once anymore. You need to select single images for each upload form element now. Sorry, but __that sucks__. – kleinfreund Aug 05 '14 at 11:25

Yahoo! has shut down Smush.It API – OC2PS Apr 22 '15 at 18:02

Your best best is to use Google's own PageSpeed script. Just install it on your server and you are good to go!
On Apache: mod_pagespeed
On nginX: ngx_pagespeed

Never used it. Sounds like it's up your alley though: http://www.imageoptimizer.net/Pages/Home.aspx

Looks like it adds some "promo" text to the bottom of the images unless you pay for it though. Someone else might have a better option.

Almost forgot about this one: http://www.gimp.org/
