Getting Graflio Images Into Amazon Seller Central

Graflio has no connection to Seller Central. It gives you files; you upload them. That is worth saying first because the rest of this page is about making that handoff boring: what Graflio exports and at what size, what Amazon actually requires as of August 2026, the file-naming rule that breaks most bulk uploads, how variation families take their images, and the six reasons an upload silently does nothing.

What comes out of Graflio

Every image in the studio is a square 1:1 canvas and exports three ways. PNG at 2,160 × 2,160 pixels, which is what you upload to Amazon. SVG at the same dimensions with the text still live, which Illustrator opens natively and Canva imports, for the last ten percent of a design. And a layered PSD at 2,160 × 2,160 where every object on the canvas becomes its own named layer above a background layer, which is what you hand a designer or keep as the archive copy.

Only the PNG is an upload candidate. Amazon accepts JPEG, PNG, TIFF and non-animated GIF, and neither SVG nor PSD is on that list. Keep those two as working files, not as deliverables. A+ modules are separate: Graflio emits five full-width modules at Amazon's Basic A+ dimensions, four at 970 × 600 and one at 970 × 300, so they go up without resizing.

2,160 pixels is not an arbitrary number. Amazon's minimum for a product image to display at all is 500 pixels on the longest side, but zoom only activates from 1,000 pixels, with 1,600 or more recommended, and zoom is where a shopper reads the stitching, the port or the ingredient panel. The practical sweet spot most photographers and agencies work to is 2,000 to 3,000 pixels; the ceiling is 10,000, and the file cap is 10 MB.

Amazon's requirements, in the form you need them

The main image is the one you cannot design your way out of. No badge, no "Best Seller" flash, no lifestyle scene, no second product in frame unless the second product is part of what you sell. The 85% rule and the pure-white rule are enforced by automated checks and, unevenly, by human review, which is why a listing can pass for eight months and then get suppressed after a routine sweep. Everything you actually want to say goes in slots two to nine, where text, callouts, comparison tables and lifestyle photography are all permitted.

One practical detail: flatten onto white rather than uploading transparency. A transparent PNG is not a white background, and Amazon judges the pixels it receives. Export the main image on an explicit 255,255,255 fill.

The naming rule that breaks bulk uploads

Three routes exist. The listing form in Add a Product, which is fine for one ASIN. Image Manager, which is fine for a handful. And bulk upload, which is the only sane option past about ten SKUs and the one with a rule people miss.

Bulk upload identifies the target slot from the file name alone: ASIN.MAIN.jpg for the main image, then ASIN.PT01.jpg, ASIN.PT02.jpg and so on for the gallery, in order. No spaces, no dashes, no extra words. A file called NEW-B0XXXXXXXX.jpg fails, and it fails quietly. The ASIN must also already be live in the catalogue, so a same-day launch that uploads images before the listing has propagated will look broken for reasons that have nothing to do with the images.

Variation families

A parent ASIN carries no images of its own that shoppers see. Each child holds its own main image, and the selected child's main image is what takes the parent's position on the detail page. Where swatch images are not supplied, Amazon renders shrunken child images in the variation selector instead, which is why an inconsistent family reads as sloppy at thumbnail size before anyone opens a single image.

Swatches are their own file type with their own spec: roughly 30 pixels on the longest side at 72 ppi, JPEG preferred. They are not scaled-down product photos. Graflio's URL import reads up to 24 colour variations from a listing, each with its own ASIN, which is the input a family-wide rebuild needs; a brand kit then holds the palette and type constant while each child's photo, colour name and callouts change.

Six reasons an upload does nothing

• File name. Wrong pattern, or spaces, dashes or extra characters in it.
• ASIN not live yet. The catalogue entry has to exist before images can attach to it.
• Main image shows a different product. Amazon rejects a MAIN contribution that does not match the product already on the ASIN. Either the image is wrong or the identifier is.
• Over 10 MB, or above 10,000 pixels, or a colour profile that is not sRGB and shifts on the way in.
• Contribution precedence. On a listing with several contributors, another party's image data can outrank yours. Brand Registry is the fix, not a resubmission.
• Propagation. Images can take hours to appear, and the old one caches. Check the next day before you conclude anything failed.

What to do before your next upload

If you have one or two SKUs, use Image Manager and check the main image against the two rules that get listings suppressed: pure white and 85% fill. If you have a variation family, build the children as a family in one pass and supply real swatches rather than letting Amazon shrink your product photos. If you have more than ten SKUs, rename to the ASIN.MAIN / ASIN.PT01 pattern and use bulk upload; the twenty minutes spent on a rename script is less than the time you will spend re-uploading one at a time.

And keep the layered file. The reason to care about PSD or SVG output is not craft, it is the day a regulator, a translation or a price change forces an edit. Flat raster with baked-in AI text means redoing the image; a layer means retyping a line. That is the whole argument, and it only becomes visible the second time you touch a set.

Common questions

Does Graflio upload to Seller Central for me?

No. There is no API connection in either direction. Graflio reads public Amazon product pages for research and produces downloadable files, and you upload those files through Seller Central yourself. Tools that publish directly save you a step; the tradeoff is that they need account access, which Graflio never asks for.

What size should I export for Amazon?

2,160 × 2,160 pixels, which is what Graflio's PNG export produces. That comfortably clears the 1,000-pixel threshold where Amazon enables zoom and the 1,600 pixels it recommends, sits inside the 2,000 to 3,000 range most professionals use, and stays well under both the 10,000-pixel and 10 MB ceilings. Square 1:1 is the right aspect ratio for both the main image and the gallery.

Can I put text on Amazon listing images?

Not on the main image, where text, logos, watermarks, graphics and inset images are all prohibited. In gallery slots two to nine you can put text, callouts, dimension diagrams and comparison charts, and you should, because that is where the selling argument lives. The same distinction applies to props and lifestyle backgrounds.

How many images can a listing have?

Up to nine image slots, of which roughly seven display on desktop by default, plus video where your account is eligible. Most categories do not reward filling every slot with something weak; a coherent set of six that each do one job beats nine that repeat each other.

Why did my image upload but not appear?

Usually propagation, which can take hours and is worsened by browser caching, so check again the following day in a private window. If it still has not changed, the likely causes are contribution precedence on a listing with multiple sellers, or a main image Amazon judged not to match the ASIN. Neither is fixed by uploading the same file again.
