ImageSEO
Automatic alt text, filenames and captions for WordPress
ImageSEO is an image optimization stack for WordPress that removes the per-image copywriting job. Once installed it generates alt text, filenames and captions automatically, and delivers optimized images including WebP, so a media library full of blank alt attributes and IMG_4273.jpg filenames becomes described and indexable without anyone writing the text by hand. That matters in two places at once: image search is still a significant share of organic traffic, and AI assistants now read alt text to understand what a page is about before citing it. The plugin has more than 94,000 downloads on WordPress.org and has processed over 17.5 million images. There is a free tier with a monthly image allowance and no credit card required, and paid plans start at 4.99 euros a month, rising through tiers that add larger monthly image quotas, multiple projects, a bulk processing queue and priority support. Every paid plan carries a 14-day money-back guarantee, and plans can be upgraded, downgraded or cancelled at any time.

Comments
ImageSEO started from a boring problem: WordPress media libraries full of IMG_4273.jpg and empty alt attributes, and nobody willing to write alt text for four thousand images by hand. The plugin does that part automatically, including WebP delivery, so a library becomes described and indexable without a copywriting session. It has passed 94,000 downloads on WordPress.org and 17.5 million images processed. There is a free tier if you want to point it at a real library and see what it produces. Happy to answer questions about how it behaves on large bulk runs.
