Product image and video quality for mobile buyers

The file itself: how heavy, how big, which format, and the one-click fix for a phone photo.

Conversion

Your photos can be perfect and still lose the sale. If the gallery takes six seconds to appear on a shaky 4G signal, many buyers never see it.

Most Egyptian shoppers arrive on a mid-range Android. Speed is conversion here, so image quality means weight as much as sharpness. This checklist covers the file itself: how big, how heavy, which format, and the one-click fix for a phone photo.

Know what your storefront can and cannot do

Two of these change what you shoot.

No zoom on the product page. One hero image and a row of thumbnails. A buyer cannot pinch to inspect a seam, so your detail shots must do that job.
You cannot reorder the gallery. The Media card shows only the first 4 photos; the rest appear as a count, such as "+2 more". Your one control is Set primary, so choose that photo carefully.
Video is a YouTube link only. The Product videos card takes a YouTube link or an 11-character video ID plus an optional caption. You never upload or compress a video file.
Lazy loading is automatic. Images below the first screen load as the buyer scrolls; the hero loads first on purpose.

Hit these numbers at upload

These are the exact thresholds Storix measures against.

Under 500 KB per image. Anything larger is flagged Too heavy.
Longest side between 800 and 2560 pixels. Below 800 is Too small, above 2560 is Too large.
WebP format. Anything else is flagged Not WebP.
Upload limit 5 MB, in JPG, PNG, WEBP or GIF.
Alt text on every photo. Without it a gallery image is flagged Missing alt text. It helps search, and buyers using a screen reader.

A master shot around 2000 by 2000 pixels sits inside these limits. Shoot square where you can: a 1:1 crop sits cleanly in product grids, on Instagram and in WhatsApp previews.

A whole-catalogue scan is coming soon

Checking every image by hand does not scale once your catalogue grows. Storix is building Catalog image health, under Products → Image health, but it is not available in the pilot yet — the page carries a "Coming soon" badge. Once it ships, it will scan your catalogue in batches, flag images that are too heavy, too small, too large, not WebP or missing alt text, and rewrite the fixable ones as a WebP copy with the longest side at most 2560 pixels — planned for the Growth and Pro plans.

Until it ships, apply the numbers above by hand: check a photo's size and dimensions before you upload it, save it as WebP, and type the alt text yourself. Too small and missing alt text will never be fixed automatically, even once the scan goes live.

Rescue a phone photo before you upload it

Most merchants shoot on a phone, and Storix has a one-click fix.

Click Improve next to an uploaded photo in the Media card.
Storix brightens it, balances the colour and sharpens it, always from your original upload.
Tick Trim background & square-frame when the edges are one plain colour.
Drag the slider to compare After and Before, then click Use improved photo.
Your original is kept — click Improved ↺ to go back.

This works on Starter, Growth and Pro, but not on Pay as you go.

Video, and the test that settles it

Keep a product video to ten or twenty seconds, readable with the sound off, and use it only where it changes the decision: how a fabric drapes, a gadget in action, the true size of a fragile item.

Then test on the device your buyers hold. Open a product page on a mid-tier Android over mobile data, not office Wi-Fi, and count the seconds until the main image is sharp. A gallery that paints in under two seconds is what keeps the click.

Storix already fixes brightness, colour and background in one click on Starter, Growth and Pro, and a whole-catalogue image scan is coming soon to Growth and Pro — compare plans.
