Compress images for BigCommerce.
Drop your photos and download them under 8 MB, the file-size limit in BigCommerce's image rules. The quality is lowered first and the pixel dimensions only when needed; the photo is never cropped. It runs in your browser; nothing is uploaded.
Under 8 MB per image, saved as JPG
Limits come from each platform's own help pages, summarised in the guides (checked 24 September 2026).

- Limit used
- Under 8 MB per image, saved as JPG
- Pixels kept
- The rules checked here state no minimum pixel size, so the tool stops before the photo falls under a quarter of its original width.
- Recommended
- 1,280 × 1,280 pixels is the optimal size for product images, though a theme's documentation may suggest a different size
- Formats
- JPEG/JPG, GIF, WebP and PNG; TIFF and PDF are not supported, and CSV imports also exclude BMP
- File size
- 8 MB maximum for each product and variant image
- Zoom
- The theme's Image sizes setting controls the zoomed image shown on hover; the API documentation says to provide an image smaller than 1,280 × 1,280 pixels for the zoom image, otherwise a resized image is returned
- Aspect ratio
- Product images used as thumbnails are best kept at the same aspect ratio; an image whose ratio does not match the theme's settings is stretched or shrunk
