What Image Optimizer by DMB actually does
The app covers the three image-SEO jobs in one pass. Compression shrinks file sizes to speed up product and collection pages, the listing’s pitch is smaller files without visible quality loss. Alt-text generation writes descriptive tags for each image, which serve accessibility and give Google context it can’t get from pixels. File renaming replaces camera-dump names like IMG_4382.jpg with keyword-relevant filenames built from custom templates and dynamic variables (product title, vendor, and so on).
The workflow has two modes that match how the problem actually shows up. Bulk mode processes your existing catalog, the accumulated years of unoptimized uploads, in one run. Auto-pilot then watches for new uploads and optimizes them as they land, so you fix the backlog once instead of re-fixing it every quarter. Every plan includes all features; tiers only change the image quota: free covers 500 images, Silver ($8.99/month) covers 5,000 and adds dedicated support with a free onboarding call, Gold ($19.99/month) covers 15,000.

Pros & cons
- All three image-SEO jobs in one app: compression, alt-text generation, and template-based file renaming
- Bulk-fixes the existing catalog, then auto-optimizes new uploads so the backlog never rebuilds
- Every feature is on every tier, plans only differ by image quota
- Free plan covers 500 images, a genuine test; $8.99/month for 5,000 undercuts most of the category
- Narrow, appropriate data access for the job (products, store pages, files)
- Launched January 26, 2026 with zero public reviews, no merchant evidence yet on compression quality or support
- No Built for Shopify badge, against category leaders with thousands of reviews
- Auto-generated alt-text needs spot-checking; generic machine descriptions don’t help rankings or accessibility
- Bulk-modifying every image in your store is exactly the kind of operation you want proof of reversibility on, test small first
- No image CDN or next-gen format serving mentioned on the listing; this optimizes your files, not your delivery stack

Before you spend trial time
- Start with a small batch (one collection), not the full catalog, verify compressed images look right on your theme at full display size, on desktop and mobile.
- Spot-check a sample of the generated alt-text and edit anything generic; alt-text only helps if it actually describes the image.
- Check whether renaming changes image URLs and how the app handles the old references, confirm product pages, theme sections, and blog posts still render every image.
- Measure a product page’s weight and load time before and after (PageSpeed Insights or WebPageTest) so the benefit is a number, not a feeling.
- Confirm the auto-pilot catches a fresh upload and applies your filename template correctly.
- Stay under the free 500-image cap until all of the above passes, then decide if the $8.99 tier earns itself.

Closing take
Image Optimizer by DMB bundles compression, alt-text, and SEO renaming with a bulk-then-autopilot workflow and pricing that makes the test nearly free, all features on every tier, 500 images at $0.
Bottom line: the job is real, the price is right, and the app is unproven. Run the free tier on one collection, check the images with your own eyes, measure the page-weight change, and scale up only on evidence.

Frequently asked questions
What does Image Optimizer by DMB actually do to my images?
Three things: compresses files to reduce size without visible quality loss, generates descriptive alt-text for SEO and accessibility, and renames files (IMG_4382.jpg becomes something keyword-relevant) using templates with dynamic variables. It can bulk-process your existing catalog and then automatically optimize new uploads.
Is there a free plan?
Yes, all features on up to 500 images. Paid tiers only raise the quota: Silver is $8.99/month for 5,000 images and adds dedicated support with an onboarding call; Gold is $19.99/month for 15,000 images.
Does image compression really affect SEO?
Indirectly but measurably: smaller images speed up pages, and page speed feeds Core Web Vitals, which Google uses. Alt-text and descriptive filenames are more direct, they’re image-ranking signals you control, and they also improve accessibility.
Is it safe to let an app rename all my image files?
Test before you trust. Renaming can change image URLs, so the thing to verify on a small batch is that every product page, theme section, and blog post still shows its images afterward. Start with one collection, confirm nothing breaks, then scale.
How good is the auto-generated alt-text?
Treat it as a first draft. Machine-written alt-text is fast and better than empty tags, but generic descriptions help neither rankings nor screen-reader users, spot-check a sample and edit where it matters, starting with your best-selling products.
How established is the app?
Early: launched January 26, 2026 by DiscoverMyBusiness, a New York agency, with no public reviews yet and no Built for Shopify badge. The data access is appropriately narrow (products, store pages, files), and the free 500-image tier exists so you can gather your own evidence.
