How to Compress Images for Amazon: Size, Format & Quality Guide

By Picovert Team2026-01-285 min read

Amazon has strict image requirements, and your main product image is the single most important asset in your listing. A poorly prepared image — wrong background, product too small in frame, or a bloated file that slows your upload workflow — can cost you sales or trigger an image suppression warning. This guide covers exactly what Amazon requires, why file size matters even when Amazon accepts large files, and how to compress product images without losing the detail that drives conversions.

Amazon Image Requirements

  • Accepted formats: JPEG, PNG, GIF, TIFF — JPEG is the standard for product photos
  • Maximum file size: 10 MB per image
  • Minimum dimensions: 1000 px on the shortest side (required to enable Amazon's zoom feature)
  • Recommended dimensions: 2000 px on the shortest side — this gives buyers the best zoom experience
  • Maximum dimensions: 10,000 px on any side
  • Recommended aspect ratio: 1:1 square — Amazon crops thumbnails to square in search results

Main Image Requirements: What Amazon Strictly Enforces

The main image (the one that appears in search results and at the top of the listing) has rules beyond general image guidelines. Amazon enforces these and will suppress listings that don't comply:

  • Pure white background only: the background must be exactly #FFFFFF. Off-white, light gray, cream, or any other near-white tone will trigger rejection. This is the most common reason for main image suppression
  • Product must fill 85% or more of the image frame: if the product appears small in a large white field, Amazon will flag it. The product should nearly fill the entire frame
  • No text, watermarks, logos, or borders: the main image must show only the product — no brand callouts, "new" badges, sale banners, or decorative borders
  • No accessories not included in the purchase: if a cable is not included with the product, do not show it in the main image
  • No mannequins, models, or props for most categories: clothing has specific rules; for most product categories the item should appear alone

Secondary and Variant Images: More Flexibility

Amazon gives you up to 9 additional image slots (for a total of 10 on most categories), and these have much looser rules:

  • Lifestyle shots: show the product in use. Colored backgrounds, natural environments, and people are all allowed
  • Infographics: callout text, feature highlights, dimensions, and comparison charts are permitted — and effective
  • Size charts and scale references: show the product next to a familiar object, or overlay actual dimensions
  • Packaging shots: show what arrives in the box, especially useful for gift-ready products
  • Multiple angles: front, back, side, close-up of key features

Secondary images can include text and colored backgrounds. Compress these to 500 KB–1.5 MB each — large enough for good detail, small enough for fast uploads.

Why File Size Matters Even Under 10 MB

Amazon accepts files up to 10 MB, and it does apply its own processing to images after upload. But uploading 5–10 MB images unnecessarily creates real problems:

  • Slow seller workflow: uploading 10 images at 8 MB each is 80 MB per listing. Multiply that across a catalog of hundreds of products, and bulk upload sessions become painful
  • Image Manager performance: Amazon's Image Manager works more smoothly with reasonably sized files
  • A+Content and brand imagery: A+ Content modules load from Amazon's CDN, but starting with properly sized source files gives you better control over final quality

The practical recommendation: compress main product images to 1–3 MB. This is well within Amazon's 10 MB limit, loads efficiently, and retains full zoom quality at 2000 px.

Compression Settings for Amazon Product Images

Amazon product photos require slightly higher JPEG quality than typical web images. This is because Amazon applies additional processing to your images — downscaling for thumbnails, generating zoom tiles, converting for mobile — and each pass slightly degrades quality. Starting with a higher-quality source compensates for this.

  • Main product image: JPEG quality 85–90. Target 1–3 MB at 2000×2000 px. This retains fine product detail through Amazon's processing pipeline
  • Secondary images (photos): JPEG quality 80–85. Target 500 KB–1.5 MB
  • Infographic and text-overlay images: PNG or JPEG quality 85. PNG is better when you have sharp text or hard edges that look bad at lower JPEG quality

Use image compression to reach these targets. Set JPEG quality to 85–90 for main images, check the preview at 100% zoom to verify no artifacts appear on product edges or textures, then download.

Getting the White Background Right

The pure white background requirement trips up many sellers. Here is how to get it right:

  • Verify the hex value: in any image editor, sample a background pixel. It must read R:255 G:255 B:255 (hex #FFFFFF). A value of R:250 G:250 B:250 looks white to the human eye but will fail Amazon's automated check
  • Use background removal tools: if your original photo was shot on a lightbox but the background reads as off-white, use a background removal tool to isolate the product, then place it on a new pure white canvas
  • Check with Amazon's ASIN image testing: in Seller Central, you can submit images through the Image Manager's image check tool before the listing goes live — use this to catch background issues before they suppress your listing
  • JPEG background creep: JPEG compression introduces subtle color variation near edges. If your background starts as pure white but the area near the product edge compresses to near-white, that is acceptable — Amazon checks the overall image, not individual edge pixels

Common Reasons Amazon Rejects or Suppresses Main Images

  • Gray or off-white background: the most frequent issue — a background that looks white on your monitor but measures off-white in Seller Central's validator
  • Product too small in frame: product fills less than 85% of the shortest side. Crop tighter or use image resizing to reframe the product
  • Watermarks or text overlays: any text visible in the main image leads to suppression, including subtle copyright marks in corners
  • Borders or vignettes: decorative borders around the image edge are not allowed in the main image
  • Accessories not included in purchase: batteries, cables, cases shown in the main image when they're not included in the order
  • Dimensions below 1000 px: images below the minimum dimension threshold disable zoom and may be flagged

File Naming for Bulk Upload via Image Manager

When uploading images in bulk through Amazon's Image Manager, file naming follows a specific convention that links the image to its ASIN and image variant:

  • Format: ASIN.VARIANT.jpg — for example, B08N5WRWNW.MAIN.jpg for the main image, or B08N5WRWNW.PT01.jpg for the first additional image
  • Common variant codes: MAIN (main image), PT01PT08 (additional images in order), SWCH (swatch), LTPT (lifestyle)
  • Case sensitivity: ASIN must be uppercase; variant codes must be uppercase. b08n5wrwnw.main.jpg will not match

Compress and rename your images before uploading via Image Manager. Keeping files at 1–3 MB means batch uploads of full catalogs complete in a fraction of the time.

Step-by-Step: Preparing Amazon Images

  1. Shoot at 2000×2000 px or larger: use a white seamless background or a lightbox. A consistent setup across all products creates a coherent listing gallery
  2. Verify the background is pure white: sample background pixels in your editor. If not #FFFFFF, use background replacement to correct it
  3. Crop so the product fills 85%+ of the frame: leave a small margin around the product — touching the edge looks wrong — but don't leave large areas of empty white space
  4. Resize if needed: if your image is larger than 3000 px, use image resizing to bring it to 2000–2500 px. This reduces file size before compression
  5. Compress to 1–3 MB: use image compression with JPEG quality 85–90. Verify the compressed image at 100% zoom — check product edges for artifacts
  6. Rename with ASIN convention: ASIN.MAIN.jpg for bulk uploads, or upload directly in Seller Central with any filename

Well-prepared Amazon images — pure white background, product filling the frame, compressed to a practical file size — improve your listing quality score, enable zoom, and speed up your upload workflow. Image compression gets you to the right file size without sacrificing the product detail that turns browsers into buyers.
