Image Resizer for Amazon Sellers
Resize Amazon product images to the right dimensions, compress file size and batch-process your catalog — free and in your browser.
Amazon Image Requirements at a Glance
Amazon's main product image must be at least 1000x1000 px (for zoom) on a white background. File sizes above 10 MB are rejected, and images should be JPG, PNG, TIFF or GIF.
For most sellers, resizing to 1000-2000 px on the longest side and compressing to under 1 MB keeps listings fast and compliant.
Batch Resizing Your Entire Catalog
The image resizer supports batch processing: upload multiple product photos, apply the same dimensions and quality settings to all of them, and download a single ZIP of optimized images.
This turns a catalog-wide image refresh from hours of manual work into a couple of minutes.
Choosing the Right Dimensions
Square 1500x1500 px images are the safest default for Amazon product pages. If your images are already larger, scale down to reduce file size without hurting zoom quality.
Lock the aspect ratio so products are never stretched or squashed during resizing.
Compress Without Losing Quality
JPG quality between 75-90% usually looks identical on screen while cutting file size dramatically. Keep the original files as backups so you can always re-export at higher quality later.
Frequently Asked Questions
What size should Amazon product images be?+
At least 1000x1000 pixels so Amazon enables zoom. 1500x1500 pixels is a comfortable standard that leaves room for Amazon's compression.
Can I resize multiple Amazon images at once?+
Yes. The batch image resizer lets you process multiple images together and download them as a ZIP.
Will resizing reduce my image quality?+
Not visibly. Resizing to standard sizes and using JPG quality of 75-90% keeps images sharp while making files much smaller.
Does Amazon reject large image files?+
Yes. Images over about 10 MB are rejected. Compressing your product photos keeps every image within Amazon's limits.
