How to Compress Images for eBay Listings Without Losing Quality
Strictly speaking, JPEG compression always discards something, but you can make the loss invisible. Listings with clear, fast-loading photos make it easier for buyers to compare items quickly.
Recommended settings for eBay listings
| Setting | Starting point |
|---|---|
| Format | JPEG (WebP where accepted) |
| Width | about 1600 px on the long edge |
| Quality | 78 |
| File size | 300 KB or less |
These are practical defaults. If the platform or form you are using publishes its own limits, follow those instead.
How to Compress Images
The trick is to remove data the eye cannot see: extra pixels beyond display size and fine noise in flat areas. Resizing to 1600 pixels and using quality 78 does exactly that.
Compare before and after at 100 percent zoom. If you cannot spot a difference at the size people will see it for eBay listings, you have compressed without visible loss.
