AltText.ai vs TinySEO (2026): which should you pick?

Pick AltText.ai if

• Fits if your store or blog has hundreds of images with no alt text
• Works for multilingual sites that need alt text in several languages

Look elsewhere if

• Tight if you're just looking, as the 25 free credits are one-off and packs cost $3 for 50
• Pricey if you have lots of images, as 2,000 a month is $59 and 10,000 is $229
• Watch out: AVIF, HEIC, SVG and TIFF cost 2 credits and need a paid plan, and each extra language is 1 more
• Watch out: changing plans forfeits that period's unused credits, and used credits are usually not refunded
• Too light for your whole SEO setup, as it only writes alt text

Pick TinySEO if

• Fits if heavy product images are slowing your Shopify store down
• Works for merchants wanting image, speed and SEO fixes in one app

Look elsewhere if

• Tight if you stay free, as it stops at 50 images and 10 AI credits a month
• Pricey if you go past your allowance, as extra images are billed one by one
• Watch out: redirects, minification, IndexNow and llms.txt start at Advanced, $23, and Search Console insights at Expert, $49
• Watch out: it was renamed from TinyIMG in July 2026, and the Shopify listing is now Tiny SEO Speed Image Optimizer
• Skip it if your store isn't on Shopify, as it runs nowhere else
