make it faster.

Here at 300FeetOut, we’re always working on making your sites faster.  Images on your site are often the largest portion of the total site load. The quality should be high as possible while minimizing their size as much as possible.  This is an ever-evolving landscape, and it’s not as simple as just uploading your favorite JPEG anymore.  But we’re doing some processing to make it easier for you.

make it easier.

To facilitate this with minimal effort we have created some useful tools for generating a large variety of image sizes so there will be an appropriately sized image for any display size. We also automatically generate WebP versions of your more standard formats like JPEG or PMG. WebP has superior compression and also makes Google happy on their Pagespeed tool.
