Fix every product image
in your store, in bulk
SEOPix scans your Shopify catalog, finds the images hurting your SEO and page speed, and fixes them: AI alt text, SEO filenames, compression, WebP. Originals backed up for 30 days.
15 free credits for new accounts · No API token to copy · Billed through Shopify
What the scan finds
One click on Scan store and every product image is checked. Read-only — nothing changes until you approve.
Missing alt text
Invisible in Google Images and to screen readers. AI writes a descriptive alt text in the language you choose.
Generic filenames
IMG_4523.jpg says nothing to search engines. Renamed to 5-10 descriptive English keywords.
Oversized images
Resized to your max dimension and recompressed. Lighter pages, better Core Web Vitals.
Outdated formats
JPEG and PNG converted to WebP — the format Shopify themes and Google both prefer.
Every original backed up
Each replaced image is stored for 30 days. One-click Restore per image from the Products page.
1 credit per image
Compression + WebP + alt text + SEO filename, all included. Failed images are refunded automatically.
From install to a fixed catalog
Install from the App Store
Install SEOPix and approve the permissions. The app runs inside your Shopify admin — you never leave it.
Your SEOPix account is created and linked automatically from your store email, with 15 free credits. No token to copy anywhere.
Choose your settings
In Settings, set output format, max dimension, quality and alt-text language (details below), then Save settings.
Scan your store
Dashboard → Scan store. You get the real numbers: how many images need attention, broken down by issue type, and how many are already fine.
Fix all — or one by one
Fix all N images processes the whole backlog, up to 50 images per run (click again to continue). Or open Products, filter by issue, and optimize image by image.
A confirmation is shown before the first bulk run so you know exactly what will change.
Restore anything, for 30 days
Not happy with a result? Products → Restore puts the original image back, with its original alt text, at its original position in the gallery.
The settings, explained
Four settings, applied to every Optimize and Fix all run. Change them anytime — they only affect future runs.
Output format
WebP · JPEG · PNG · Keep originalWebP is the default and the right answer for almost every store: same visual quality, much smaller files. Pick JPEG only if you need maximum compatibility with an old theme, PNG if the image needs transparency, or Keep original to compress without converting.
Max dimension
1024 · 1600 · 2048 · 2700 · 4096 pxApplies to the longest side. 2048 px is Shopify's recommendation and the default — it stays sharp on retina screens without weighing pages down. Drop to 1600 or 1024 px if page speed is your priority, go to 2700 or 4096 px only if customers zoom deeply into product details.
Quality
50 to 95 (default 85)85 is the sweet spot: no visible loss, big size reduction. Below 70 artifacts start showing on flat backgrounds and gradients. Above 90 you pay in kilobytes for a difference nobody sees.
Alt text language
EN · FR · ES · DE · IT · PT · NL · ZHPick the language your customers browse in — alt text is read by them and by Google in that market. Filenames always stay in English: that's what performs in image search worldwide.
