An F on GTMetrix for “optimise images”?

The GTMetrix scoring system can be misleading. The report identified 8 images, which, if optimized better, can give you a 2% improvement (only), yet it scores the page as just 5 out of 100.

Of the 8 flagged images, 6 are served from your server and 2 are served from Google Maps.

The reason those 6 images are not served by Sirv is that Sirv can auto-detect most but not all images. If you manually embed an image in a page, Sirv won’t detect it. Those 6 images are background images in your theme. You can serve them from Sirv by going to the page template and changing the image URLs to use the URLs from your Sirv account instead.

More importantly, one of those images is an enormous 5760 × 3840 pixels and 8MB in file size:

It’s much bigger than needed. You can upload it to your server again, at about 2000px width. Or upload it to Sirv and update your WordPress template to reference it on Sirv instead.

If you’re not comfortable with editing the code of your WordPress theme files, you can leave them as they are and the files will be served from your server. The Sirv plugin for WordPress is always being improved, so one day it may be able to sync your background images too.

Fair enough.

Perhaps an easier option would be a way to manually submit them to Sirv?

Was assuming you’d have a bulk resize option like smush, any plans?

Other plugins like Smush work differently. They compress an image and overwrite the original on your server. Your server then serves a single smaller image.

Sirv is more intelligent. It doesn’t constantly serve just one image – it serves the most optimal image for each user depending on their browser, their viewport, screen their resolution. One image could be processed and cached into lots of different sizes. The images are stored on Sirv, so they don’t take up space on your server. They are served by Sirv CDN, so load on your server is lower and the image is served from the closest edge location around the world.

To optimize those 6 images, you can upload them to your Sirv account, then update the image location in the appropriate template in your WordPress site.

Ok, got all that.

Thanks, will have a twiddle ?? .

Re: Smush – being able to replace/mirror my WP media gallery with yr optimised images was my meaning, appreciate your approach (why I installed!), yet leaving unoptimised files in WP kinda defeats the purpose/leads to confusion. At the least make it an option.
As it is I installed Smush, smushed everything, then resized manually with Imsanity (coz Smush also missed the same files, maybe something to explore there).

EDIT: really could do with a sort by filesize in yr online interface, kinda makes finding the oversized files downright implausible.

And that concludes my feedback ??

Useful feedback, thank you! Using our plugin to resize/compress files on the users server is something we’re a little uncomfortable with because it results in irrevocable loss of resolution and quality. Our approach is to preserve the master and use it to generate the optimized image on-the-fly, though there’s certainly a place for a service that downwsizes images on the users WP server forever. It would blur the lines a little if the Sirv plugin could do that and there are already other plugins that can do that, so as it stands, resizing master images on WordPress is unlikely to be a capability added to the Sirv plugin.

However, sort and search by filesize in the Sirv web app is absolutely going to be added. It’ll be a useful feature for many Sirv users and we’ll release this as part of the advanced search options that’s on our roadmap.

Thanks again ??
