How to Prepare Product Images for E-Commerce (Amazon, Shopify, Etsy)

How to Prepare Product Images for E-Commerce

Product images are the single most influential factor in online purchase decisions. Shoppers cannot touch, smell, or try your product — the image carries that entire sensory job. Research by Shopify consistently shows that image quality and variety directly impact conversion rates, with high-quality images increasing purchase intent by 30–40% compared to low-quality alternatives.

Getting images right also keeps your listings compliant. Amazon suppresses listings that violate image guidelines. Etsy can reduce search visibility for listings with low-resolution images. Investing in proper image preparation is not optional — it is table stakes.

Amazon Product Image Requirements

Amazon has the strictest image requirements of any major marketplace, and violations result in listing suppression.

Main image (hero) rules:

• Pure white background — RGB values must be 255, 255, 255 (not off-white or light gray)
• Product must fill at least 85% of the image frame
• Minimum 1000px on the longest side (for zoom functionality — go for 2000px)
• Maximum 10,000px on any side
• JPEG format strongly preferred; TIFF and PNG accepted but JPEG is standard
• No watermarks, text, borders, or additional graphics
• No mannequins for apparel — use flat lay or modeled shots

Additional image slots (up to 9 total):

• Can show lifestyle images, close-ups, size charts, and infographics
• White background not required for secondary images
• Same size minimums apply

File size: Amazon accepts up to 10 MB per image, but aim for under 2 MB for faster upload processing.

Shopify Product Image Requirements

Shopify is more flexible than Amazon but has strong recommendations that affect storefront performance.

Recommended specifications:

• Square aspect ratio (1:1) — 2048x2048px is the Shopify-recommended target
• JPEG for photographs (best balance of quality and file size)
• PNG for graphics, logos, and images requiring transparency
• Maximum file size: 20 MB (but keep under 1 MB for fast page loads — more on this below)
• sRGB color profile (not CMYK, which is for print)

Why square images? Shopify themes are designed around square product grids. Non-square images get letterboxed with white padding or cropped, often inconsistently across different themes and devices. Shooting or cropping to square from the start avoids this.

For a Shopify store, also upload WebP versions where possible — Shopify's CDN serves WebP automatically to supporting browsers, but uploading WebP directly gives you control over the source quality.

Etsy Listing Photo Requirements

Etsy has looser technical requirements but strong guidance that affects search performance.

Requirements and recommendations:

• Minimum 2000px on the shortest side
• Recommended aspect ratio: 5:4 (1500x1200px or 2500x2000px)
• JPEG or PNG accepted
• sRGB color profile
• Maximum file size: 1 MB per image (Etsy resizes larger files automatically, which can reduce quality)
• Up to 10 photos per listing — use all 10 for better search visibility

Etsy-specific tips: The first image is your thumbnail in search results. It needs to look great at small sizes — avoid cluttered compositions or text that becomes illegible when thumbnailed. Etsy's algorithm also favors listings where buyers engage with multiple photos, so varied angles and context shots genuinely improve rankings.

The Standard Product Image Workflow

Regardless of platform, the preparation workflow is the same:

Step 1: Shoot or source the raw image Shoot in good natural light or with a lightbox. Use the highest resolution your camera supports. Shoot on a white or neutral background if possible — it simplifies post-processing.

Step 2: Remove the background For product-only shots, remove the background to get a clean white or transparent version. PixConvert's background remover handles this in the browser — your product photos are processed locally and never uploaded to a server. For Amazon, replace transparency with pure white (255,255,255) after removal. For Shopify and design use, keep transparency in PNG format.

Step 3: Resize to platform specifications Resize to the target dimensions. Use PixConvert's image resizer to hit exact pixel dimensions. For Amazon: 2000px minimum on the long side. For Shopify: 2048x2048px square. For Etsy: 2500x2000px or similar 5:4 ratio.

Step 4: Compress for web delivery File size directly affects page load speed, which affects conversion rates. A 4 MB product image on a Shopify page is a performance problem. Target under 500 KB per image, ideally under 300 KB.

Use PixConvert's image compressor to reduce file size. For photos, 80–85% JPEG quality hits the sweet spot — visually identical to the original at roughly one-quarter the file size.

Step 5: Convert to the right format

• Amazon listings: JPEG
• Shopify: JPEG for photos, PNG for graphics; consider also exporting WebP for CDN optimization
• Etsy: JPEG for most images, PNG if you need transparency

Convert between formats using PixConvert's JPG to PNG converter when transparency is needed, or PNG to WebP for optimized web delivery.

File Naming for SEO

Rename your files before upload. File names are an SEO signal — especially on Google Images, where product discovery is significant for e-commerce.

Bad: IMG_2847.jpg, product_001.jpg, final_v3_FINAL.jpg

Good: handmade-leather-wallet-brown.jpg, ceramic-coffee-mug-12oz-white.jpg, womens-linen-trousers-navy-size-12.jpg

Use descriptive, hyphenated names that include the product name, key attributes (color, size, material), and optionally the brand. Keep names under 60 characters. Never use spaces or special characters.

Color Profile: sRGB Is Non-Negotiable

Images destined for the web must use the sRGB color profile. CMYK is a print color space — browsers cannot render it correctly and will display colors that look muddy or shifted. If your images are coming from a professional photographer or print studio, explicitly request sRGB exports.

Most smartphone cameras and consumer DSLRs capture in sRGB by default. Check in Photoshop (Edit > Convert to Profile > sRGB IEC61966-2.1) or in any image editor before upload.

Batch Processing Large Catalogs

If you are launching a store with hundreds or thousands of SKUs, manual image-by-image preparation is not practical. PixConvert handles batch processing: drag in multiple files, apply the same compression or conversion settings, and download the results as a ZIP.

For a catalog migration — say, moving 500 product images from PNG to compressed JPEG — batch conversion saves hours. Process groups of images by category or product type to keep the workflow organized.

The 1 MB Rule

Regardless of platform, no individual product image on a live storefront should exceed 1 MB. Most should be under 500 KB. Slow-loading images increase bounce rates, hurt Core Web Vitals scores, and reduce conversion rates. A properly compressed 2000px JPEG product photo at 80–85% quality should land between 150–400 KB — plenty of quality for zoom and retina displays, at a fraction of the raw file size.
