Images: alt text, compression and file names
How Whittle writes alt text for your whole Shopify Files library, compresses photos while keeping the originals for undo, and renames files with SEO file names.
In short: The Images page covers every photo in your Files library, not just product photos. Whittle writes alt text, compresses photos while keeping the originals so any change can be undone, and gives files SEO-friendly names.
Alt text
Alt text is a short written description of a photo. Google Images and screen readers rely on it because they can't see the picture. Whittle writes it for products, collections, posts and the rest of your Files library. Each photo description counts as one AI fix.
Compression
Smaller photos load faster. Whittle compresses them and keeps the originals for undo. Free includes 50 a month, Pro 1,000, Growth 3,000 and Scale 10,000.
SEO file names
Renames files like IMG_2041.jpg to names that describe the product. Whittle checks first that no post links straight to the file, so renaming doesn't break anything.
