Generate Alt Text for a Batch of Images

In this tutorial, we’ll create an image project, upload a few images, review the alt text our tool writes for each one, edit one description, and export everything as a CSV. By the end, you’ll have a spreadsheet of alt text ready to use.

You’ll need a Content Studio account. If you don’t have one yet, start with Create your account.

In the sidebar, select Image alt text. (The same button sits at the top of your My Projects page.) It carries a Beta badge, and a lock icon if your plan doesn’t include image work — Free accounts can’t create one yet.

Drag a handful of images into the upload area, or click to browse — three or four is enough to see the whole flow quickly.

You can also drop a ZIP of images, or a CSV listing image URLs. The type is detected automatically, so there’s no mode to pick first. Use the CSV route when you have more images than you’d want to upload by hand.

Give the project a name and set the Description language.

Expand Branding & context to name your brand, products, partners, website, and tone. These help our tool describe your images the way you’d describe them — skip them for this first run and fill them in later.

Select Generate descriptions.

4. Wait for our tool to describe your images

Section titled “4. Wait for our tool to describe your images”

Our tool looks at each image and writes alt text for it. For a handful of images, this is quick.

Open your project to see the review screen: one row per image, each showing the image itself, a category our tool assigned, and its written alt text.

  1. Read through a couple of them. Notice how the wording changes based on what’s actually in each image.
  2. Pick one and click its alt text to edit it.
  3. Change a word or two, then save.

Notice your edit replaces our tool’s version — the export in the next step uses exactly what you typed.

Click Export, then choose CSV.

A CSV file downloads to your computer, with one row per image and its final alt text — your edited version included.

That’s your visible result: a spreadsheet of alt text, ready to hand to a developer or paste into a CMS.

A JSON export is also available if that suits your workflow better — see the how-to guide on generating image alt text in bulk for both formats and the CSV/ZIP/URL-list upload options.

You’ve created an image project, generated AI alt text for a batch of images, edited one by hand, and exported the results as a CSV.
