Large, uncompressed product photos slow down page load times and can push you close to marketplace upload limits, while images that are too small or heavily compressed can fail Amazon’s zoom-quality requirements or simply look unprofessional to shoppers. The right balance is a file that loads fast but still looks sharp at full size and on zoom.
This tool lets you compress an existing image to reduce its file size, or resize it to specific pixel dimensions - useful for meeting a marketplace’s minimum resolution requirement or standardizing image dimensions across a catalog. Everything runs locally in your browser, so nothing is uploaded to a server.
What image size does Amazon require for product listings?
Amazon’s main product image typically needs to be at least 1000x1000 pixels on the longest side (to enable zoom) and file size limits vary by upload path, but staying under a few MB per image is a safe general target. Always check current requirements in Seller Central for your specific category, since exact rules can change.
Does compressing an image reduce its quality?
Some quality loss is possible with lossy compression (like standard JPEG compression), but at moderate compression levels the difference is usually invisible to the eye while cutting file size significantly. This tool lets you preview the result before downloading, so you can balance file size against visual quality.
What image formats does this tool support?
JPEG, PNG, and WebP - both for compressing existing images and for resizing them to specific dimensions.
Is anything I upload here stored or sent to a server?
No. Compression and resizing happen entirely in your browser - your images are never uploaded or stored anywhere.
Image size and quality requirements vary by marketplace and category - confirm the current specification for your listing before relying on any specific pixel dimension or file size.
