What is Amazon's maximum product image file size?

Amazon allows up to 10MB per image. But most sellers upload RAW photos straight from their camera at 15-30MB, which gets rejected. Compress to under 4MB for best results.

What resolution do Amazon images need to be?

2000×2000px minimum for zoom to work. 1000×1000px is the absolute minimum. Anything smaller and Amazon turns off the zoom feature, which drops conversion by 20%.

Does Amazon accept WebP images?

No. Amazon only accepts JPEG, PNG, TIFF, and GIF. Always upload JPG compressed files for Amazon listings.

Bulk Compress Amazon Product Photos (Meet Amazon's File Limits)

Published: August 28, 2026 · 5 min read

Every Amazon seller has been there: you've got 50 product listings, 20 photos each, all straight from your camera at 20MB per file. When you try to upload them to Seller Central, Amazon rejects half of them for being over 10MB. You could open Photoshop 1000 times and compress each one manually, but that takes an afternoon. Our bulk image compressor compresses 50 photos at once, right in your browser, no upload, no Photoshop.

Amazon's Exact Image Requirements

Format: JPEG (preferred), PNG, TIFF, GIF. No WebP.
File size: Max 10MB per image. We recommend targeting 1-4MB for fastest upload.
Resolution: Minimum 1000×1000px for zoom, recommended 2000×2000px for best quality. Max 10,000×10,000px.
Color mode: sRGB. Don't upload Adobe RGB photos — Amazon converts them and the colors look washed out.
Background: Pure white for main images (Amazon's strict requirement).

The most common rejection reason is file size over 10MB. A raw JPG from a modern phone is 8-15MB, which is already over the limit for most cameras.

Step-by-Step Bulk Compression Workflow

Select all your product photos in our bulk compressor. You can upload up to 100 at a time.
Set compression quality to 75% — that's the sweet spot for Amazon: file size drops by 70% with no visible quality loss on product photos.
Check "resize to 2000×2000px" — this automatically resizes any larger images down to the recommended Amazon size, which makes the files even smaller.
Click compress. All files process locally in your browser, then download as a ZIP.
Upload the compressed JPGs directly to Amazon Seller Central — every file will be under 4MB, 2000×2000px, and meet all Amazon requirements.

Your original product photos never get uploaded to any server. This is especially important if you have unreleased products — no one else can access your shots.

Why Compress Locally Instead of Using Amazon's Built-In Compression?

Amazon does compress images after you upload them, but:

If your original file is over 10MB, Amazon rejects it outright before it can compress it.
Amazon's compression is inconsistent — sometimes it leaves files at 8MB, sometimes it squashes them too much and they look blurry.
Uploading 20MB files takes forever. At 4MB per file, uploads are 5x faster. If you have 100 listings, that's hours saved.

Compressing before you upload also means you control the quality — you can make sure your product photos look sharp, not whatever Amazon's compression decides to do.

Common Mistakes

Compressing too much: If you set quality below 60%, your product photos will look pixelated when customers zoom in. Stick to 70-80% quality for Amazon.
Not resizing before compressing: A 4000×4000 photo compressed to 2MB is still 4000×4000px, which is way bigger than Amazon needs. Resize to 2000×2000 first, then compress — that cuts file size by another 50%.
Uploading PNGs for product photos: PNG files are 5-10x bigger than JPGs for the same product photo. Use JPG for regular product shots, only use PNG if you need a transparent background.
Forgetting sRGB color mode: If you shoot in RAW and export in Adobe RGB, the colors will look off on Amazon. Export as sRGB JPG.

How file size impacts your Amazon conversion rate

It's easy to think image compression is just a technical step to avoid upload rejections, but the size of your product photos directly impacts how fast your listing page loads, and how well it converts. Amazon's mobile shoppers make up 70% of all Amazon traffic, and most of them are browsing on 4G or public wifi connections. If your product images are uncompressed 8MB files, your listing page takes 5-6 seconds to load on mobile, and every second of delay drops your conversion rate by roughly 7%. Compressing your images down to 1-2MB each cuts that load time to under 2 seconds, and you'll see a measurable lift in sales without changing your price, your copy, or your reviews. Most sellers never think to optimize their image file sizes, which means it's one of the easiest, lowest-effort ways to get a conversion boost against your competitors.

Another hidden benefit of pre-compressing your images is that Amazon's search algorithm actually favors faster-loading listings. When Amazon compares two products with identical reviews, prices, and sales history, the listing that loads faster will get ranked higher, because Amazon cares about the customer experience — they don't want to send shoppers to slow, clunky pages. A lot of sellers spend hundreds of dollars on PPC ads trying to climb search rankings, but they never stop to realize that simply compressing their product photos could give them an organic ranking boost for free. The zoom feature that Amazon offers on 1000px+ images is also a huge conversion driver: internal Amazon data shows listings with zoom-enabled images convert 15-20% better than those without, because shoppers can zoom in to see product details before they buy. Resizing all your photos to exactly 2000x2000px before compressing ensures that zoom feature is enabled on every single listing, which is another free conversion lift you get just by doing this one small step.

For sellers who manage hundreds of SKUs, doing this bulk compression once and building it into your standard product upload workflow saves dozens of hours every quarter. Instead of dealing with rejected uploads, slow page loads, and blurry zoom images, you just run all your new product photos through the compressor before you upload them, and you never have to think about image issues again. It's a 2-minute step per batch of photos, but it eliminates a whole category of listing errors that can cause suppressed listings, lost sales, and bad customer reviews from blurry product photos. A lot of new sellers spend weeks troubleshooting why their listings aren't converting, never realizing the problem is just that their product photos are too big and too slow to load on mobile.

One last thing: when you're compressing product photos, make sure you keep a master copy of the original uncompressed files on your own hard drive. The compressed JPGs are optimized for Amazon's requirements, but if you ever need to re-shoot, edit, or use those photos for your own website, social media, or marketing materials, you'll want the full-resolution original. The compressor runs entirely in your browser, so your original files never get modified — it just creates compressed copies that you upload to Amazon, and your originals stay untouched on your computer. That way you get the fast-loading, Amazon-compliant images you need for your listings, without losing the high-resolution files you need for everything else. It's a small habit, but it saves you from having to re-shoot products six months later when you need a high-res version for a marketing campaign.
