FAQ
Frequently asked questions.
How does client-side compression work without third-party API keys?
CompressPrivacy runs modern WebAssembly and Canvas encoding routines directly inside your browser tab on your computer. Your computer’s CPU compresses the images before sending the resulting WebP/AVIF files to WordPress, so no cloud API keys or external server dependencies are required.
Is there any limit on how many images I can compress?
No. Because compression runs locally on your machine rather than through a metered cloud SaaS, you can optimize an unlimited number of images completely free of charge with zero monthly caps.
Where do I access the compression tool in WordPress?
All optimization takes place on a dedicated screen: Media → Bulk Optimizer. You can drop batches of images, configure your target quality and output format, and upload them directly into your Media Library.
Will this slow down or crash my WordPress hosting server during large batch uploads?
No. Traditional image optimizer plugins cause server CPU spikes and timeouts when processing large image batches on shared hosting. CompressPrivacy does all the heavy lifting on the client side, sending only pre-compressed, lightweight files to your server.
