Premium A+ Content is built around large, visual assets. When those images look sharp in Photoshop or Canva but appear soft, pixelated, or blurry after upload, changing random export settings is not the best way to troubleshoot the problem.
Amazon has specific technical requirements for A+ images, including file format, file size, resolution, color space, and module dimensions. Amazon also states that images larger than the allowed module dimensions may be resized by the A+ tool. Recent seller discussions show that blurry Premium A+ images continue to be reported, particularly on mobile.

First, check whether the file or Amazon’s rendering is the problem
Before redesigning the image, compare three versions:
- The original exported file on your computer.
- The image inside A+ Content Manager.
- The published product detail page.
This matters because a file can be technically correct before upload and still look different after Amazon processes it. Sellers have repeatedly reported images becoming blurry or pixelated after upload, including cases where the source files were created at the recommended dimensions.
Amazon also provides a Content quality analysis area in A+ Content Manager. Its current A+ documentation says Amazon evaluates visual presentation, readability, completeness, and other quality factors and can provide recommendations. Amazon has separately stated that blurry or low-quality images can be part of that assessment.
So the first diagnostic question should be:
Does the image look blurry before upload, during the A+ editing process, or only on the live page?
That tells you where to focus.
Use the correct Premium A+ dimensions
Amazon’s current A+ help page lists:
Premium A+ image size: 1464 × 600 pixels
Amazon also says Premium A+ contains 19 module types and that the Premium A+ format uses larger images than Basic A+.
However, this does not mean every Premium A+ module uses a 1464 × 600 file.
Amazon’s dedicated Premium A+ Module Guide states that there are specific requirements for each module type. The safest workflow is therefore to select the exact module in A+ Content Manager and use the dimensions shown for that module rather than forcing every asset into one canvas size.
The dimension rule that matters
Use the exact pixel dimensions required by the module you are creating.
For the Premium full-width format, Amazon’s published reference is:
1464 × 600 px
Do not confuse that with a universal size for every Premium A+ asset. Amazon’s own documentation distinguishes between the general Premium A+ image reference and module-specific requirements.
Do not assume 1200 × 900 is an Amazon requirement
You will find seller discussions recommending 1200 × 900 for mobile Premium A+ images. One long-running Amazon Seller Forums discussion contains exactly that recommendation from a seller.
That is useful as a seller workflow, but it is not the same thing as an Amazon-published current requirement.
Amazon’s current A+ documentation lists Premium A+ as mobile optimized and gives 1464 × 600 as the Premium A+ image-size reference. It does not, in the current documentation reviewed here, establish 1200 × 900 as a universal mobile Premium A+ requirement.
So do not redesign an entire catalog around 1200 × 900 simply because it appears in older seller advice.
Check Amazon’s file requirements before changing the design
Amazon’s Premium A+ Module Guide gives four technical requirements that should be checked before upload:
| Requirement | Amazon’s specification |
|---|---|
| File type | JPG, BMP or PNG |
| Maximum file size | 2 MB per image |
| Resolution | At least 72 dpi |
| Color space | RGB |
| Animated GIF | Not supported |
Amazon also states that images exceeding the maximum dimensions for a module may be resized to fit, while images smaller than the module limits will not be resized upward to meet them.
That last point is particularly important when diagnosing blurry images.
Oversized files can be resized by Amazon
Suppose a Premium module calls for a particular maximum dimension and you upload a substantially larger image.
Amazon’s guide explicitly says that images that are too large will be resized to fit the maximum sizes listed for each module. It also says that images smaller than the module limits will not be resized to meet those limits.
That means you should not treat “bigger is always better” as an Amazon rule.
A common workflow is:
Design → export → resize to the required pixel dimensions → verify file size → upload
rather than:
Design → export an enormous file → let Amazon resize it
The second workflow gives Amazon’s processing system more work to do and makes it harder to know exactly what version of the asset you are evaluating.
Amazon does not state that every instance of image blur is caused by resizing, so it would be wrong to claim that resizing is always the reason an image becomes blurry. It is, however, a documented processing step for oversized Premium A+ images.
Don’t confuse DPI with image sharpness
Amazon specifies a minimum of 72 dpi.
But changing a file from 72 dpi to 300 dpi does not automatically create more pixels.
For web-based content, the actual pixel dimensions are what determine how much image information is available to display. A 1464 × 600 image remains 1464 × 600 pixels whether its metadata says 72 dpi or 300 dpi.
This is why increasing the DPI number alone is not a solution to a blurry Premium A+ image.
Focus first on:
pixel dimensions → image quality → compression/file size → rendering
rather than changing DPI repeatedly.
Keep the color space in RGB
Amazon’s Premium A+ guide specifies RGB and says CMYK is not supported.
So check the document’s color mode before exporting.
This is particularly important when a designer receives artwork prepared for print. A print-focused CMYK workflow should not simply be uploaded to Premium A+ without converting the working file to an Amazon-supported RGB workflow.
Amazon does not require “sRGB” specifically in the Premium A+ guide cited here. It requires RGB. So claims that Amazon mandates a particular sRGB export setting should not be presented as an Amazon rule.
Choose JPG or PNG based on the asset
Amazon accepts both JPG and PNG for Premium A+ images.
There is no Amazon instruction in the cited Premium A+ guide saying that PNG is always sharper than JPG or that JPG is always preferable.
A sensible production approach is to choose the format according to the artwork:
Photography: JPG is generally efficient.
Graphics with large flat areas, sharp text, or transparency: PNG can preserve those elements without JPEG-style lossy compression.
But the final file still has to meet Amazon’s file-size limit.
Amazon’s documented requirement is 2 MB maximum per image, not a particular JPEG quality percentage.
So claims such as “Amazon requires JPEG quality 85%” are not supported by the Amazon documentation reviewed here.
What to do when a file is larger than 2 MB
Do not immediately reduce the physical dimensions below Amazon’s module requirement just to make the file smaller.
Instead:
- Keep the required pixel dimensions.
- Export in an Amazon-supported format.
- Reduce unnecessary metadata or other file overhead.
- Adjust compression until the file is below 2 MB.
- Inspect the resulting file at 100% before uploading.
The objective is to stay within Amazon’s file-size requirement without unnecessarily reducing the pixel dimensions needed by the module.
Avoid repeated resizing
One of the easiest ways to lose quality is to resize the same image repeatedly.
For example:
4000 px → 2500 px → 1800 px → 1464 px
is less controlled than creating the final 1464 × 600 asset directly from the high-resolution source.
Keep the original master file untouched and create the Amazon upload file separately.
For a professional workflow, maintain:
Master artwork → Amazon export → uploaded asset
rather than editing the already-compressed Amazon version every time.
Text is often the first thing to look blurry
A Premium A+ image can look acceptable as a photograph but still appear poor because the text embedded inside the graphic becomes soft.
This is especially noticeable when:
- thin fonts are used
- text is very small
- fine lines are used
- there is low contrast between text and background
- several compression/resizing steps have already occurred
Amazon’s current A+ quality guidance specifically considers readability and visual presentation when assessing content quality.
Amazon does not publish a universal font-size rule for text that is baked into A+ graphics in the sources reviewed here. So there is no evidence-based reason to claim that a specific number of points is an Amazon requirement.
The practical test is whether the text remains clearly readable in the actual published module, especially on a phone.
Mobile needs its own QA check
Do not judge Premium A+ only from your desktop design application.
Recent Amazon seller discussions show repeated reports of images appearing significantly softer on mobile than expected, including sellers who had already tested multiple dimensions and export formats.
Amazon itself currently identifies Premium A+ as mobile optimized, but mobile optimization does not guarantee that every design will look equally sharp on every screen.
Your QA should therefore include:
Desktop: Check the live product page at normal browser zoom.
Mobile: Open the actual product detail page on a phone.
Text: Check small copy and fine graphical details.
Images: Look for softness, pixelation, unexpected cropping, or stretching.
Comparison: Compare the published result with the original export.
This is more useful than repeatedly changing Photoshop settings without checking the actual customer-facing page.
Be careful with browser zoom and display scaling
Not every apparent blur problem is caused by Amazon.
A recent Reddit discussion about blurry Premium A+ images included a seller who discovered that operating-system display scaling was affecting how the page appeared on their monitor.
That does not prove that browser scaling is responsible for most A+ quality issues. It does show why testing the live page on more than one device is important.
When investigating a problem, test at normal browser zoom and, where practical, on an actual mobile device.
Check the live page before changing everything
Another recurring point in seller discussions is that the A+ preview can look worse than the published version.
Because this is seller-reported rather than an Amazon technical specification, it should not be treated as a guaranteed behavior.
Still, it is a useful QA rule:
Do not make a final judgment from the editor preview alone.
Publish a controlled test and inspect the live product detail page.
If the live page is sharp, the problem may have been limited to the preview environment.
If the live page is also blurry, continue troubleshooting the actual asset and module.
A useful troubleshooting sequence
Do not change five variables at once.
Use this sequence instead.
Step 1: Check the module
Confirm which Premium A+ module is displaying the blurry image.
Record the exact dimensions Amazon shows for that module.
Step 2: Check the file dimensions
Open the exported file and confirm its actual pixel dimensions.
Do not rely on the dimensions of the Photoshop or Canva canvas if the exported file may have been resized during export.
Step 3: Check the file size
Confirm that the final file is no larger than 2 MB.
Step 4: Check the color mode
Confirm that the file is RGB, not CMYK.
Step 5: Check the format
Confirm that the file is JPG, BMP or PNG.
Step 6: Check the source
Open the exported file outside Amazon.
If it is already blurry there, the upload is not the original problem.
If it is sharp locally but becomes blurry after upload, continue testing the Amazon-side result.
Step 7: Test the live page
Check the published ASIN rather than relying exclusively on the A+ Content Manager preview.
Step 8: Check mobile
Open the live listing on a phone and compare it with desktop.
Step 9: Check Amazon’s Content Quality analysis
Open A+ Content Manager and review any quality recommendations Amazon provides. Amazon says its quality system evaluates visual presentation and readability among other factors.
Step 10: Escalate only after the basics are verified
If the file meets Amazon’s documented requirements, looks sharp locally, and is still materially degraded on the published listing, document the issue before opening a Seller Support case.
Include:
- ASIN
- A+ project
- module type
- original file
- final uploaded file
- exact pixel dimensions
- file format
- file size
- desktop screenshot
- mobile screenshot
- description of where the quality changes
That gives support a reproducible problem instead of a general complaint that the A+ image “looks blurry.”
What not to use as a troubleshooting rule
Several popular recommendations are not supported strongly enough to treat as Amazon requirements.
“Use 300 DPI.”
Amazon requires at least 72 dpi. Increasing DPI by itself does not add pixels.
“Always upload at 2× or 3×.”
Seller discussions contain recommendations for larger files, including 2× and 3× workflows, but Amazon’s documentation explicitly says oversized images can be resized to fit module limits. There is no universal Amazon rule in the cited documentation requiring 2× or 3× Premium A+ artwork.
“PNG is always better.”
Amazon accepts both JPG and PNG. It does not state that one is universally superior.
“1200 × 900 is the required mobile size.”
That figure appears in an older seller discussion, but it should not be presented as a current universal Amazon requirement without current Amazon documentation supporting it.
“Amazon compression is always the cause.”
Sellers frequently report post-upload quality loss, but Amazon’s documentation reviewed here specifically confirms resizing of oversized files; it does not establish that every blurry image results from compression.
The Premium A+ image QA checklist
Before publishing, verify:
Dimensions: Match the Amazon requirement for the specific module.
Premium reference: Use 1464 × 600 where the applicable Premium A+ module calls for that size.
File size: 2 MB or less.
Format: JPG, BMP or PNG.
Resolution: At least 72 dpi.
Color: RGB.
Source quality: Sharp before upload.
Preview: Check inside A+ Content Manager.
Live page: Check after publishing.
Mobile: Check on an actual phone.
Text: Confirm that small text and fine details remain readable.
Content quality: Review Amazon’s Content quality analysis recommendations.
Final takeaway
Fixing blurry Premium A+ Content is not about finding one magical Photoshop export setting.
Start with Amazon’s documented requirements.
Use the correct dimensions for the module. Keep the file at or below 2 MB. Use JPG, BMP or PNG. Keep the file in RGB and meet the 72 dpi minimum. Most importantly, do not confuse a seller-recommended workaround with an Amazon requirement.
For Premium A+, Amazon currently identifies 1464 × 600 as the image-size reference, while its dedicated module guide makes clear that specific modules can have their own requirements.
Once the technical specifications are correct, compare the original file, Amazon’s preview, and the live product page. Then test both desktop and mobile.
If the local file is sharp, the asset meets Amazon’s requirements, and the published version is still visibly degraded, document the exact module and ASIN and escalate the issue rather than repeatedly changing export settings.
