Frequently Asked Questions

What happens if an error occurs during the optimization process? Will my images not load?

Don’t worry, it’ll still load. If optimization fails, PicPerf will simply fall back to serving the actual image, preventing broken links. Your visitors always get a working image.

What happens if I suspend my subscription while my site is still using PicPerf links?

We’ll just serve the original image. No optimizations will occur, no cache headers will be applied, and no network-level caching will be implemented. There will be no value added to anything, but you’ll still get images rendered to your page while you migrate links. We’ll keep those links active for at least 30 days. If you need an extension, just ask.

I changed the source image. Why is the new version not appearing on my site?

PicPerf aggressively caches images, which means any particular file name (including query parameters) is locked to a specific version of the image. Even if the image were purged from all remote caching layers, it’s also configured to be cached on a user’s personal device for up to a year. For this reason, if you’d like to change the image, change the name of the file. For example, instead of https://picperf.io/https://my-image.jpg, use https://picperf.io/https://my-image-2.jpg.

Why am I not getting a .webp or .avif version of my image back?

If the converted format is a larger size than the original format, PicPerf will always serve the smaller one. This shouldn’t happen for most images, but may be the case for some.

Are animated GIFs supported?

Yes. Animated GIFs will be converted to a .webp format (assuming that format is lighter than the original for the given image), and still be animated when you load it onto a page. It’ll just be much lighter. Even if it doesn’t come back in a different format, all unnecessary metadata will be removed, making it lighter. For more information on supported image formats, see here.

What’s the maximum image size I can use?

Anything over a couple megabytes may result in optimization errors, causing the original image to be returned. That said, you’ve got other problems if you’re trying to display an image of that magnitude on a page.
