Supported Image Formats
PicPerf can optimize just about any image format used on the web. Specifically, that list includes:
- GIF (animated GIFs are cool too!)
For all of these formats, PicPerf will perform a basic optimization on the original format, and then attempt to reformat & optimize it to a modern format. No matter what, you’ll get a faster image at the other end of the request (unless an optimization has already occurred before PicPerf got a hold of it).
Resulting Image Formats
After an optimization has been performed, you could get one of two image formats back.
Original Format (PNG, JPEG, etc.)
Depending on the image (albeit in frequently), the original image format may be lighter than the “modern” formats it was converted into. In these cases, the resulting image will remain in the original format, but be stripped of unnecssary metadata, giving it at least a marginal boost in optimization.
WebP is an extremely well-supported, modern image format announced by Google back in 2010.
A relatively new format, AVIF compresses images with AV1 in the HEIF container format. Its specificiation was finalized in 2019, and has since achieved support in all major browsers.
