Best way to optimise images?

I am trying to speed up my website by optimising images.

Its a slow process and I am using webpagetest to optimise my images.

Whats the best way to do this in bulk? Is there any online or software that you recommend?

Thanks

Does site speed effect your SEO on Google?

I don't know of any way to do this in bulk unfortunately. Each image is it's own case anyways so it would be ill advised. You may reduce an image to piss poor quality and upload it for a while without knowing it because you did it in bulk. It takes some time but I normally just reduce the size of images in photoshop. If you do some research, I'm sure you'll find some posts with guidelines on how to reduce them/how far to reduce them (ex. 72 dpi should be fine, you don't need 300dpi for an image unless it's a photographers portfolio).

There is no concrete evidence yet that site speed affects your ranking (which is what I assume you mean by SEO on Google) but there is a correlation with site speed and rank. This article on moz.com shows a correlation between the time to first byte and ranking. This is only correlation though, not causation. I believe this could be because brands who show up higher in a SERP likely are investing in SEO.

Another study shows that, on average, 7% of your visitors drop off for ever extra second after 2 it takes your site to load. This, again, is across many sites and should be taken on a case by case basis but Amazon famously reduced their page load time by 1ms and earned themselves an additional millions and millions of dollars (I forget the exact number but it was an obscene amount). So site speed is worth it for more viewers (which I assume is the point of your site).

TL;DR
No way to reduce images in bulk
Site speed won't improve your rankings but totally worth the effort

Thanks for your reply CredibleZephyre.

I use Imageoptim to optimize my images just drag and drop. But it's only for macs.

Site speed definitely effects your SEO rankings and image optimization can play a huge role in this. We recently did a blog post where we looked at the best way to optimize your images. http://www.aseohosting.com/blog/2014/03/the-dos-and-donts-of-image-optimization/ Hope this helps.

As above, don't try and reduce the file sizes in bulk.

Individually, if using Photoshop to create your images use the Save For Web & Devices option instead of plain old Save As.

If you are using wordpress; I use this plugin: EWWW Image Optimizer

Why don't you host your images on some other server, like flickr or imgur.

This will minimise the pressure on your own server and will increase the speed.

Try kraken.io
It helps me to cut image size by 30-40% without sacrificing quality.

Once you save them in Photoshop, open the saved jpg, png, or gif in Photoshop again, I think it's under image > adjustments > posterize. Slide it back and fourth until it you find an acceptable setting. To low makes it look like crap, to high increases file size. It slowly removes colors since the human eye can't see all the colors the image contains (some BS like this). Save it again via Save for web. Google "reducing image size with posterize" there is a video tutorial that goes in depth. I have been able to cut images in half using just this.

To do it in mass go to yahoo smush.it. You can upload a bunch at a time and it strips the files of meta data that isn't needed for seeing the image.

The other thing you could look for is a JavaScript lazy loader. This will load images after page load like pinterest.

Load speed most definitely affects SEO. Anyone who says differently is missing a huge opportunity.

I will suggest you the image script, Its a best idea...
Do research on that..
