## Frequently asked questions

What does the Image Optimiser actually change?

It compresses oversized images and writes missing alt text. Optimised versions are only re-uploaded to your CMS after you approve them.

Will compression make my images look worse?

No. Compression is tuned to reduce file size while keeping images looking the way they should.

Why does alt text matter?

It helps Google understand your images and makes your site accessible to people using screen readers.

Does it upload changes automatically?

Only after approval. You review the proposed changes first, then the agent re-uploads the optimised versions to your CMS.

How much faster will my pages be?

It depends on how heavy your images are now, but oversized images are one of the most common causes of slow pages, so there is usually plenty to gain.
