What is a 1000×1000 image?
A 1000×1000 pixel image is a perfect 1:1 square holding exactly one megapixel. It is the sweet spot for online selling: 1000 pixels is the minimum Amazon needs to switch on its hover-to-zoom, and it is large enough for eBay and Etsy listings while staying a light, fast-loading file. Learning how to resize an image to 1000x1000 once means a photo that fits every marketplace slot.
- 1:1 square ratio — no awkward cropping in a product grid
- 1 megapixel — sharp on screen yet light enough to load fast
- ≈ 3.33 × 3.33 in (8.5 × 8.5 cm) at 300 DPI for small prints

Frequently Asked
A 1000×1000 pixel image is a perfect 1:1 square with exactly one million pixels (1 megapixel). It is the go-to square size for online marketplaces — 1000 pixels is the minimum Amazon needs to enable its zoom feature, and it displays crisply as an Instagram or eBay listing thumbnail without any cropping.
Upload your image above and the width and height are set to 1000×1000 automatically. That is all it takes to resize an image to 1000x1000 — pick your output format (JPG, PNG or WebP) and click Download. Everything runs in your browser, so there is no software to install and no account to create.
Square 1000×1000 images are the standard for e-commerce product photos (Amazon, eBay and Etsy all accept or recommend a 1000px square main image), Instagram square feed posts, marketplace and catalog thumbnails, and square profile pictures. The 1:1 shape means the same file drops cleanly into a product grid, a social feed and an avatar slot.
This tool is preset to 1000×1000, so both the width and the height become 1000 pixels. If you only need to resize an image to 1000 pixels on one side while keeping the original proportions, use the full Image Resizer on the homepage: turn on the aspect-ratio lock, type 1000 into the width, and the height updates automatically.
Enlarging always adds some softness because the browser has to interpolate new pixels. Going from a small thumbnail up to 1000×1000 can look a little blurry, but because 1 megapixel is a modest target, most phone and camera photos are already larger than 1000px and will downscale to a sharp, clean square.
