Automatically add and optimize all your product image alt texts. Customize your alt text template with various variables. Schedule an update when you need it.

Gets the job done fast and efficiently, Ease to use, highly recommended.

Superb little app. It's very handy, I use it all the time and it works very well.
— Little Ones Preloved
Great app and easy to use!
— Maxxteknik
Very effective application. Deserves 5* +. To recommend!
— Xios Store SNC
Wonderful. It works! Wish I googled this sooner.
— P.A.M. (Perks And Mini)
Great service at a reasonable price
— Kpughdesigns
Works as advertised. I asked for a new feature to distinguish multiple images for a single product so they don't all have the same alt text. This way, Google would know they are different. They added the feature in less than 24 hours. Great.
— CALI Strong
Très bon travail, surtout pour ce prix, ajouter a leurs application pour compresser les images, c'est nickel
— Designix
Would recommend them will save you lots of time so you can run your business.
— Nvrift Adventures
For a cost of $1.99 I've managed to rewrite detailed alt-tags for over 9,000 images. You simply can't get better than that - highly recommended app, thank you!

Does what it's supposed to do - I heard Shopify's Director of Product discussing the functionality of this app as something they would like to offer in the future on the "Shopify Masters" podcast, but this app offers auto-generated Alt text already. Too bad it can't also pick up on images added to the description. Other than that a great app and a great price.

For now everything is perfeckt! Saved me tons of time, optimized around 3 000 images in less than hour.. All in 3 clicks. Great work
— ImaginVibes
I installed this app and it was loading for over 24hours and it created the same alt tag for all of my unique products. No one responded to my message either. waste of time Not good for women's boutique with different products

Je n'ai pas vu le résultat encore

It’s great to get images quickly optimised. But BEWARE. After days of work optimising all the alt descriptions manually, this app wiped out all my hard work and rest it. So although it was great in the beginning, it’s actually ended up costing me days of lost work and effort. Totally gutted. I would suggest only loading this app if you are intending never to optimise the images yourself. OR im...

This app saved me hours of time! My shop has over 200 products, and alt text was added to every photo within minutes.
— The Note House
All images optimized with customizable wording. Really happy for the money. Although 100 words is a lot to write!
— Essential CBD
Super easy to use, just install, play around with the parameters you want to use for your alt text then all your images are updated within around 30-60 mins! So good to know it runs daily so if we add new images it's not ever something we need to worry about.
— Duncan Stewart 1978
What a great service, especially for accessibility. I can not even imagine how long it would have taken us to do this ourselves. And the best part is it does not touch our themes.
— LOOK OPTIC
Great App, this is a must-have for all Shopify sellers out there! your images will get optimized in seconds!
