Why Amazon A+ Images Look Blurry After Upload and How to Fix It

If your Amazon A+ or Premium A+ images look sharp in Figma, Canva, Photoshop, or your export folder, but look blurry after upload, the problem is usually not one single export setting. Many sellers try every file size, format, scale, and output setting, then still see soft or fuzzy images on the live mobile product detail page.

That usually means the issue is deeper than PNG vs JPG. It is often a workflow problem across source-photo quality, module ratio, compression, mobile readability, and live product detail page QA.

The practical fix is to stop treating A+ as a set of beautiful banners and start treating it as product detail page content that has to survive resizing, mobile scanning, and shopper trust checks.

Quick Answer

Amazon A+ and Premium A+ images usually look blurry after upload because the asset is being resized into the wrong module shape, the design uses tiny text or icons that fail on mobile, the source image is already soft, or the team only checks Seller Central preview instead of the live product detail page. Fix the module fit first, simplify mobile text, use clean source files, and review the live PDP on desktop and mobile.

Most A+ blur issues come from a chain of small production decisions, not one magic export setting.

Why This Problem Matters

Blurry A+ content is not just a design annoyance. It can make the whole product detail page feel less trustworthy.

Amazon Ads recommends improving product detail pages with high-quality images and says sellers should use images at least 1000 pixels in height or width as a best practice for zoom support. It also recommends four or more high-quality images to help shoppers engage with the product page.

That lines up with buyer behavior. Salsify's 2025 Consumer Research reports that 77% of shoppers rate product images and videos as very or extremely important, and 70% have returned an item because of incorrect product content.

For A+ content, the implication is clear: clarity is not only about looking polished. It is part of how buyers decide whether the page is credible.

The First Question: Is It Actually Blurry or Just Unreadable?

Sellers often describe two different problems with the same word:

What you seeLikely issueWhat to check first
Product edges look softWeak source image, over-compression, or upscalingOriginal product photo at 100% zoom
Text looks fuzzyToo-small text, thin fonts, or mobile scalingPhone-width preview and live PDP
Icons look messyToo many small detailsRemove decorative icons or enlarge them
Banner looks croppedWrong module ratio or unsafe layoutA+ module size and crop area
Everything looked fine before uploadRepeated compression or wrong export sourceOriginal design file and upload asset
Image looks fine in Seller Central but worse liveBrowser/device rendering differenceLive desktop and mobile PDP

Before changing export settings, identify which problem you actually have. A text-heavy module can feel blurry even if the image file is technically sharp.

Why A+ Images Look Blurry After Upload

1. The asset is not built for the exact module shape

Amazon A+ and Premium A+ modules have different visual jobs. A wide image, a comparison chart image, a brand story tile, and a feature card should not all start from the same canvas.

When a design does not match the module shape, the final view may be forced into scaling, cropping, or awkward resizing. Use public pixel lists only as planning references. The final check should happen in A+ Content Manager.

2. The source image is already too weak

If the original product photo is soft, noisy, low-resolution, over-cropped, or over-sharpened, A+ design will amplify the problem.

This happens often when a seller uses a marketplace thumbnail, an old cropped listing image, a compressed file from chat apps, or a generated product image that changed label edges or material texture.

Fix this before you design the module. If the product label, edge, texture, or key feature is not clean in the source asset, it will not become trustworthy after upload.

3. The design is too dense for mobile

This is the most common hidden cause.

Many A+ modules are designed like desktop banners:

  • small comparison labels
  • tiny certification badges
  • long ingredient callouts
  • icons with thin strokes
  • text placed over product photography
  • multiple claims inside one image

That may look acceptable on a desktop preview. On a phone, the same module becomes a small compressed visual block. The shopper does not experience it as "too much information." They experience it as "blurry."

4. Thin typography fails after compression

Thin fonts, light gray text, tiny uppercase copy, and low-contrast labels are fragile in ecommerce images.

If a module has to survive upload compression and phone display, use:

  • heavier font weights
  • fewer words per line
  • strong contrast
  • larger spacing
  • fewer decorative lines
  • fewer icon-label combinations

The goal is not to make the design louder. The goal is to make the message remain clear after the marketplace has processed it.

5. The team reviews the wrong surface

Seller Central preview is useful, but the live PDP is the real surface. Review the final page on desktop, mobile browser, Amazon app if relevant, and the actual ASIN after the A+ content is live.

A Practical Fix Workflow

Use this workflow before redesigning everything.

Step 1: Confirm the module fit before changing export settings

If you have already tried different file sizes, formats, and scales without improvement, stop changing export settings for a moment.

First confirm:

  • the exact A+ or Premium A+ module being used
  • the upload requirement shown in A+ Content Manager
  • whether your canvas matches that module's shape
  • whether important text or product detail sits too close to the edge
  • whether the module becomes stacked or compressed on mobile

This catches the most common workflow problem: a technically sharp file being forced into the wrong display shape.

Step 2: Check the source at real size

Open the source product image at 100% zoom before placing it into an A+ module. Look for fuzzy label text, jagged edges, visible noise, color shift, over-smoothed texture, or inaccurate shape.

If the source is weak, run product-photo cleanup or reshoot before building the A+ module.

Step 3: Decide the job of the module

Every A+ module should have one main job:

Module jobBetter content choiceWhat to avoid
Show brand trustLogo, proof point, simple positioningLong paragraph inside image
Explain product benefitOne claim plus one visual proofFive benefits in one banner
Compare variationsClear table or product lineupTiny thumbnails and dense labels
Explain use caseOne scene or one before/afterCollage with too many scenes
Reduce uncertaintySize, material, compatibility, ingredientsDecorative lifestyle-only visual

If the module has more than one job, split it.

Step 4: Simplify mobile text

Use this rule: if the shopper cannot understand the image in three seconds on a phone, the module is too dense.

Before upload, reduce tiny badges, long captions, multiple icons, thin dividers, decorative microcopy, and text over busy backgrounds. Replace them with one headline, one supporting line, one clear product visual, and one proof point or use case.

Step 5: Export clean, then test live

There is no universal export setting that fixes a bad A+ layout, but you can avoid avoidable damage: export from the original design file, keep the canvas matched to the module requirement, use high-resolution source product photos, avoid repeated compression, and check the live PDP after publishing.

If You Have Already Tried Every File Size

This is the point where many sellers get stuck. They export PNG, JPG, larger files, smaller files, different scales, and different compression settings, but the mobile PDP still looks blurry.

When that happens, run this test:

  1. Duplicate the module.
  2. Remove 50% of the text.
  3. Double the size of the remaining headline.
  4. Remove small icons and thin dividers.
  5. Keep the product visual and one core claim.
  6. Compare the live mobile PDP.

If the simplified version looks clearer, the real issue was readability and mobile scaling, not file format.

Fit the Module, Not the Design File

Do not design a generic hero banner and force it into every A+ placement.

Instead:

  1. Choose the A+ module first.
  2. Confirm the upload requirement in Seller Central.
  3. Build the image for that module ratio.
  4. Keep the important product detail away from edges.
  5. Preview what happens when the module is stacked on mobile.

This reduces resizing and crop surprises.

Common Mistakes Sellers Make

Mistake 1: Reusing one image for every placement

An image that works as a listing support image may not work as an A+ module. Reuse the idea, not the exact canvas.

Mistake 2: Designing A+ content like a brochure

A+ content is not a PDF brochure. It is part of a product detail page where shoppers scan quickly. Dense claims and crowded feature blocks often create visual fatigue.

Mistake 3: Fixing blur with more sharpening

Sharpening can make edges look harsher, but it does not fix poor layout, tiny text, or wrong module sizing. Fix the cause before sharpening the output.

Mistake 4: Ignoring mobile because desktop looks fine

Many A+ complaints are really mobile complaints. Review the mobile PDP before judging whether the design is done.

Mistake 5: Letting AI change the product

AI can help clean up product visuals and create lifestyle context. But if it changes the label, shape, material, or product color, the image may become less trustworthy even if it looks sharper.

Where LoomaDesign Fits

LoomaDesign is useful when the source product visual needs to become cleaner, more structured, and more reusable across ecommerce assets.

  1. Use AI Product Image Enhancer when the source photo is usable but too soft, dull, or inconsistent.
  2. Use Amazon Listing Image Generator when the product gallery needs clearer secondary images and structured listing visuals.
  3. Use Amazon A+ Content AI when the team needs a full A+ content structure, not only one cleaned-up image.
  4. Use the Amazon A+ Content Dimensions Checklist before building the final modules.

The key is not to generate more images blindly. The key is to create product visuals that stay clear, accurate, and useful after they land on the actual product detail page.

FAQ

Why do my Amazon A+ images look blurry after upload?

They usually look blurry because the source image is weak, the A+ module resizes the asset, the layout uses tiny text, or the live mobile PDP makes the design harder to read. Start by checking the original source image and the module ratio before changing export settings.

Does Amazon compress A+ images?

Marketplace platforms process uploaded images for delivery, performance, and display. You should assume your design needs to survive resizing and compression. That means using clean source images, matching the module ratio, and keeping text readable.

What size should I export Amazon A+ images?

The safest answer is to confirm the current requirement inside A+ Content Manager for the module you selected. Public size lists can help planning, but the upload interface is the final source of truth because module options and marketplace requirements can change.

Should I use PNG or JPG for Amazon A+ images?

Use the format accepted by the upload interface and best suited to the asset. Product photography often works well as JPG when exported cleanly. Graphic-heavy modules with text and flat shapes may benefit from PNG, but file handling and Amazon upload requirements should decide the final format.

Why does the image look sharp on desktop but blurry on mobile?

The file may be sharp, but the design may be unreadable after scaling down. Thin fonts, tiny labels, dense icons, and low-contrast copy often fail on phone screens. Treat mobile readability as a design requirement, not a final preview step.

Can AI fix blurry Amazon A+ images?

AI can help when the issue is source-image clarity, background cleanup, or product-photo enhancement. It cannot safely fix a module that has too much text, the wrong ratio, or an inaccurate product visual. Use AI to improve the asset, then still review the final A+ design on the live PDP.

Sources and Data Points

If you are building the next content asset, start with the Amazon A+ dimensions checklist, then use the AI product image enhancer when the source visual itself needs cleanup.
