How to Get a JPEG Under 300 KB for Marketplace Ads
Hitting an exact size limit is easier with a target-size compressor. Classified and marketplace ads benefit from several quick-loading photos rather than one slow, heavy one.
Recommended settings for marketplace ads
| 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 Get a JPEG Under 300 KB
Type 300 into the target size box. The tool tries different quality levels and keeps the best one that fits. If even low quality cannot fit, it gradually reduces the dimensions until it does.
For very tight limits, crop first so the subject fills the frame. A tightly cropped image at 300 KB will look far better than a wide scene squeezed to the same size.
